William Llewellyn's ANABOLICS, 10th ed.
ANABOLICS is a reference manual of drug compounds used to enhance body composition, strength, and/or athleticperformance. This book includes an extensive review of the history, global availability, and application ofanabolic/androgenic steroids, as well as related performance-enhancing drugs such as human growth hormone, insulin,anti-estrogens, diuretics, reductase inhibitors, and fat loss agents. The core focus of ANABOLICS is to provide a nonbiasedand comprehensive review of the current science surrounding these drugs, as well as their medical and non-medical use.
The effort of this book is always to help readers understand the potential risks of these drugs, in addition to their benefits.
ANABOLICS is not intended to promote steroid or other drug use, but is designed to help readers, may they be physicians,patients, or illicit users, better understand these drugs, and make well-informed decisions about them.
Regular readers will notice the latest edition includes updates and new additions in the following sections: Anabolic Overview (Part I):
Part I was extensively updated in the 9th Edition of ANABOLICS, though the 10th Edition has seen some minor edits, andthe addition of a section on AAS-linked tendon injury.
Practical Application (Part II):
A new chapter of Counterfeit Steroid Detection has been added. It discloses techniques for identifying deviant productswith a handheld microscope.
The Harm Reduction section has been modified, along with a follow-up chapter on Sterilizing Injectable AAS preparations.
The Post-Cycle Therapy section has been updated to include a modified PCT program, and Start of PCT timing calculations.
An Off-Cycle Therapy (OCT) section has been added, which discusses ways to better retain muscle mass between cycles,and make follow up programs more productive.
A chapter on Obtaining AAS has been added, which covers the popular ways these medications are obtained. This sectionincludes advice about reducing risks.
Drug Profiles (Part III):
Updates concerning drug manufacture and global availability have been made in most of the commonAnabolic/Androgenic Steroid Profiles.
New or extensively re-written profiles have been added for Catapres (clonidine), Geref (sermorelin), Glucophage(metformin), and BP Stabil.
Steroid Availability Tables (Appendix A):
Global steroid manufacturing status has been extensively updated. Many dozens of new steroid preparations have beenadded, and numerous out of commerce steroids have been removed.
Photographic Database (Appendix B):
The photographic database has been extensively expanded, and includes approximately 3,000 pictures ofanabolic/androgenic steroids and other drugs. Legitimate pharmaceuticals are labeled and grouped by their country ofmanufacture. The following terms are used to identify the origin of individual drug products.
Real (or no specification other than country): These legitimate pharmaceutical products are distributed in
pharmacies or veterinary clinics in the labeled country of origin. Real drugs offer the greatest assurance of product
purity and safety, although production standards may vary by country or market (veterinary/human).
Counterfeit (CF): This is an illicit duplicate of a real drug product and/or manufacturer. These items are of
unknown quality and safety, and often contain substitute or no steroid ingredients.
Export (EX): These are drugs made by registered pharmaceutical companies, but are not licensed for sale in their
William Llewellyn's ANABOLICS, 10th ed.
country of origin. They must be exported. Export products should be made in legitimate pharmaceutical manufacturing facilities, but depending on the region may not be made under the same close government supervision as locally distributed products.
Underground (UG): These products are made from unlicensed illegal manufacturers specifically for sale on the
black market. Due to the completely unregulated nature of these drugs, they offer little assurance of quality, and
are generally not recommended.
Fake: This is an illicitly manufactured drug that purports to be a real pharmaceutical, but bears no relation to an
actual product. Fake is a distinction that suggests all forms of the photographed steroid should be considered
NLM: Indicates a drug that is No Longer Manufactured. This distinction is important because when NLM drugs are
still found in active black market commerce they usually turn out to be illegitimate.
New Service (HRT-Rx):
As longtime advocates of the legitimate medical use of anabolic/androgenic steroids, we have launched HRT-Rx, a national
referral service to help patients find progressive HRT/Anti-Aging physicians. Network doctors are the type that regularly
work with testosterone medications, and understand the value of hormone replacement and optimization therapies. You
can find a physician near you at Note that most offices require you are at least 30 years of age to make
an appointment.
New Service (HRT-Labs):
We have also partnered with a laboratory that can run extensive blood tests including hormone levels, liver/kidneyenzymes, and general health markers. The service is available in all 50 states and can be accessed at

There are some concerns with initiating testosterone Blood testosterone levels below 350ng/dL are usually replacement therapy when the individual is in poor regarded as clinically significant, although some health. One study examined the safety of HRT in men physicians will use a level as low as 200ng/dL as the aged 65 and older with limited mobility and various threshold for normal. Hypogonadism is, unfortunately, still health conditions such as obesity, hypertension, diabetes, widely under-diagnosed.

Patient compliance Transdermal: Transdermal application is the most and comfort are high with this form of therapy, as there commonly prescribed method for supplementing are no special routines or requirements aside from taking testosterone in the United States and Canada, and is a few capsules each day with meals. Oral testosterone generally the first course of therapy initiated with undecanoate is usually given at an initial dosage of 120 to androgen replacement therapy patients. This method of 160 mg per day, which equates to three to four 40 mg drug delivery offers a number of advantages to the capsules. This dosage may be reduced in subsequent patient when compared to injection. Since the weeks to 120 mg per day.

While this form of therapy is highly application also provides stable day-to-day hormone convenient, serum hormone levels can fluctuate greatly levels, and does not produce the broad fluctuations on a day-to-day basis. The amount of fat consumption has usually noticed with injectable testosterone esters. The a particularly strong impact on hormone bioavailability, most common protocol among hormone replacement and meals providing at least 20 grams of fat are doctors is to prescribe a dosage of 2.5-10 mg of recommended when taking the capsules for maximum testosterone per day (approximate absorbed dose). This is absorption. Note that as with transdermal testosterone, applied as a rub-on gel or adhesive transdermal patch oral testosterone undecanoate tends to increase serum that is replaced daily. Note that due to metabolism in the dihydrotestosterone (DHT) levels more profoundly than skin, transdermal application of testosterone tends to increase serum dihydrotestosterone (DHT) levels moreprofoundly than testosterone injection.

This shows very clearly that it is far more rare toabuse these drugs and not notice side effects than it is toendure them.90 In addition to the side effects thatanabolic/androgenic steroids can have on various internalsystems, there are others which may not be immediatelyapparent to the user. The following is a summary of thebiological systems and reactions effected by AAS use.
The use of anabolic/androgenic steroids insupratherapeutic (and often therapeutic) doses can havea number of adverse effects on the cardiovascular system.

This adverse effect is mediated periods, however, their adverse effects on the through the androgenic stimulation of hepatic lipase, a cardiovascular system are given time to accumulate. An liver enzyme responsible for the breakdown of HDL increased chance of early death due to heart attack or (good) cholesterol.91 With more hepatic lipase activity in stroke is, likewise, a valid risk with long-term steroid abuse.

This is an effect that seems to be very the cardiovascular system in several key ways.

For example, studies with testosterone cypionate noted a 21% drop in HDL cholesterol with a dosage of 300mg per week.92 Increasing this dosage to 600 mg did not Anabolic/androgenic steroids use can adversely affect have any significant additional effect, suggesting that the both HDL (good) and LDL (bad) cholesterol values.

Sample Steroid Cycles
The following cycles are presented as examples of common steroid administration protocols. These programs have notbeen evaluated in a clinical setting for safety and efficacy, and are provided for informational purposes only. These are notrecommendations for anabolic/androgenic steroid use. As with any supplemental drug program, it is important to examineyour own individual health status, health risks, and performance goals before deciding to engage in anyanabolic/androgenic steroid use. For those who have made the decision, it is important to emphasize again that therecommended approach to AAS use is to limit drug intake to the lowest levels necessary to achieve the next rational goal.
More aggressive cycles should not be attempted unless one is sure they cannot achieve the results needed on a moremoderate program. Note that given the difficulty in predicting androgenic threshold and dosages for female users, thebelow cycles are examples of programs for men only.
Single Agent Cycles
Dianabol Cycle #1 (Mass)
100 tablets 5 mg Methandrostenolone All Weeks:
Liver Support: Liver Stabil, Liv-52, or Essentiale Forte (label recommended dosage).
Cholesterol Support: Lipid Stabil (3 caps/day) and Fish Oil (4 g/day).
Estrogen Support: tamoxifen (10-20 mg/day).
This is a very common first cycle for building muscle mass, and utilizes a single standard bottle ofmethandrostenolone. This cycle is likely to produce very noticeable muscle growth in a first-timesteroid user, often in excess of 8-10lbs of weight gain. This is usually not accompanied by significantvisible side effects such as gynecomastia and water retention. Although this is considered a beginner'scycle, methandrostenolone is a c-17 alpha alkylated oral steroid, and presents significant cardiovascularand liver toxicity. The repeated use of such drugs should be limited.
William Llewellyn's ANABOLICS, 10th ed.
Stack Cycles
Deca/Dianabol Cycle #1 (Mass)
10 mL 200 mg/mL nandrolone decanoate 100 tablets 5 mg methandrostenolone All Weeks:
Liver Support: Liver Stabil, Liv-52, or Essentiale Forte (label recommended dosage).
Cholesterol Support: Lipid Stabil (3 caps/day) and Fish Oil (4g/day).
Estrogen Support: tamoxifen (20-40 mg/day).
This is an extremely old and widely repeated steroid combination, based on the predominantly anabolic steroid nandrolone decanoate. Methandrostenolone serves as the androgenic component of this stack, and is added during week 3, which is a time that side effects of reduced androgenicity (with the exclusive use of nandrolone decanoate) are commonly noticed, such as loss of libido and sexual dysfunction. The doses used in this cycle are not high by most bodybuilding standards, but are sufficient to impart a noticeable increase in muscle size and strength.
William Llewellyn's ANABOLICS, 10th ed.
Deca/Dianabol Cycle #2 (Mass)
20 mL 200 mg/mL nandrolone decanoate 200 tablets 5 mg methandrostenolone All Weeks:
Liver Support: Liver Stabil, Liv-52, or Essentiale Forte (label recommended dosage).
Cholesterol Support: Lipid Stabil (3 caps/day) and Fish Oil (4g/day).
Estrogen Support: tamoxifen (20-40 mg/day).
A more popular manifestation of the Deca/Dianabol Cycle, with more commonly accepted dosages for a moderately experienced steroid user. Incidences of side effects are expected to be higher at these dosages, although overall this stack is likely to be less problematic than a combination of testosterone and oxymetholone.
William Llewellyn's ANABOLICS, 10th ed.
Testosterone/Anadrol Cycle (Mass)
20 mL 200 mg/mL testosterone (enanthate or cypionate) 100 tablets 50 mg oxymetholone All Weeks:
Liver Support: Liver Stabil, Liv-52, or Essentiale Forte (label recommended dosage).
Cholesterol Support: Lipid Stabil (3 caps/day) and Fish Oil (4g/day).
Estrogen Support: tamoxifen (20-40 mg/day).
A combination of testosterone and oxymetholone is generally regarded as the most potent 2-drug stack for gaining raw muscle mass. Both drugs will present significant estrogenicity, and will be likely to induce gynecomastia quickly unless an estrogen maintenance drug such as tamoxifen is used.
Inexperienced steroid users have been known to gain over 25-30 pounds on a cycle such as this. Water retention will be very high with this stack, however, and a rapid loss of water weight (possibly up to 10 pounds or more) is expected soon after the cycle is discontinued.

Real ampules, vials, and tablets are between legitimate pharmaceutical products and sometimes smuggled loose, but let someone else take the illegitimate copies (counterfeits). Before we begin, I need risk. The box for a pharmaceutical product should be to remind you that counterfeiting anabolic steroids is a structurally sound, closing tightly and evenly. Some very lucrative business these days. Counterfeiters are counterfeiters seal their own boxes by hand, and they may investing a lot of money in printing and packaging be uneven or poorly glued. Real boxes should be printed equipment so that you'll have a hard time picking out (ink directly on cardboard). Some counterfeiters cover their products. Furthermore, there are now many large plain white boxes with stickers. If the vial, ampule, or bottle "commercial scale" counterfeiting operations, with the has a label, machines should have put it on straight.

Some counterfeiters use ampules, but blank strips. Given this high level of sophistication, steroids laboratory samples.

The mistakes made by counterfeiters are often ampule, and somewhat unusual in appearance. A good minor, and noticed in the fine (not obvious) detail.
rule of thumb is to avoid any steroid that does not comein a professional looking package.
Step #1: Eliminate the Obvious
When counterfeit steroids first appeared decades ago,they were often very easy to spot. The manufacturersoperated on a small scale, and made small-scale mistakes.
For example, the printing might be sloppy, or the The ampule [right] is a

Still, that is not tosay that obvious counterfeits aren't available. Indeed, theycan be found on the black market from time to time. Thisfirst set of instructions, therefore, seeks to eliminate onlythe most obvious fakes. For the rest, we will need a moredetailed analysis.

The characters on a real pharmaceuticalproduct should stand out from the rest of the printing,which will consist of tiny dots blended together to createa solid image (see Step #3 for more information on theink). When the lot/expiration information is added with amechanical stamp, the ink will be much more solid undermagnification (note that it may appear blotchy underdeep magnification).

Step #2: Examine Lot Number/Expiration
A more formal analysis should always begin with the lotnumber/expiration date. Pharmaceutical companies havetheir boxes and labels manufactured in bulk, usually at anoffsite printing facility. They are not serialized; lotnumbers/expiration dates have not yet been applied to them. This information is added with a mechanicalstamping machine or computer/inkjet printer at the timethe drug is packaged. Counterfeiters often don't wait, and Example #1. A real box of Proviron.

In addition to this, however, there are also have already been discussed, and unfortunately concentrated forms of insulin available for patients that consuming more carbohydrates during sleep will not be require higher doses and a more economical or an option. Those experimenting with insulin would, comfortable option to U-100 preparations. In the U.S., therefore, be wise to always stay awake for the duration of products containing as much as 5 times the normal the drug's effect, and also avoid using insulin in the early concentration, or 500 IU per milliliter, are also sold. These evening to ensure the drug will not be inadvertently are identified as "U-500" preparations, and are available by active when retiring for the night. It is also important to prescription only.

This information can concentration. Given the general difficulty in accurately spare valuable (perhaps life saving) time in helping measuring athletic doses (2-15 IU) with a drug of such medical professionals establish a diagnosis and provide high concentration, U-100 preparations are used almost exclusively for physique- and performance-enhancing Side Effects (Lipodystrophy):

It is, therefore, critical to insulin may cause a localized allergy. This may include understand the warning signs of hypoglycemia. The irritation, swelling, itching, and/or redness at the site of following is a list of symptoms that may indicate mild to injection. This often subsides as therapy continues. In moderate hypoglycemia: hunger, drowsiness, blurred some instances it may be due to an allergy to an vision, depressive mood, dizziness, sweating, palpitation, ingredient, or in the case of animal insulin, a protein tremor, restlessness, tingling in the hands, feet, lips, or contaminant. Less common, but potentially more serious, tongue, lightheadedness, inability to concentrate, is a systemic allergic reaction to insulin administration.

There is always a possibility of severe Given that there are varying forms of insulin available for hypoglycemia, which is very serious and requires medical use with differing pharmacokinetic patterns, as immediate emergency medical attention. Symptoms of well as products with different drug concentrations, it is this include disorientation, seizure, unconsciousness, and extremely important that the user be familiar with the William Llewellyn's ANABOLICS, 10th ed.

Rapid-acting insulin preparations (Novolog, slightly higher insulin requirements, as HGH therapy is Humalog, and Humulin-R) are the most popular choices shown to both lower secretion of, and induce cellular for physique- or performance-enhancing purposes, and resistance to, insulin.
the subject of the dosing information presented in this One must also remember that it is very important to book. It is also important to stress that before one consume carbohydrates for several hours following considers using insulin they should also become very insulin use. One should generally follow the rule-of-thumb familiar with using a glucometer. This is a medical device of ingesting at least 10-15 grams of simple carbohydrates that can give you a quick and accurate reading of your per IU of insulin injected (with a minimum immediate blood glucose level. This device can be indispensable in intake of 100 grams regardless of dose).This is timed 10 to helping one manage and optimize their 30 minutes after subcutaneous injection of Humulin-R, or immediately after using Novolog or Humalog.The use of a carbohydrate replacement drink is often used as a fastcarbohydrate source. Properly cautious insulin users will Short acting forms of insulin (Novolog, Humalog, always have a source for simple sugars on-hand in case an Humulin-R) are designed for subcutaneous injection.

Many Following subcutaneous injection, the injection site athletes will also take creatine monohydrate with their should be left alone and not rubbed, to prevent the drug carbohydrate drink, since the insulin may help force more from releasing into circulation too quickly. It is also creatine into the muscles. 30-60 minutes after injecting advised to rotate subcutaneous injection sites regularly to insulin, one should also eat a good meal and consume a avoid the localized buildup of subcutaneous fat that may protein shake. The carbohydrate drink and meal/protein develop due to the lipogenic properties of this hormone shake are absolutely necessary, as without them blood (see Adverse Reactions: Lipodystrophy). The medical sugar levels may drop dangerously low and the athlete dosage will vary depending on the individual may enter a state of hypoglycemia (see Adverse requirements of the patient. Furthermore, changes in such Reactions: Hypoglycemia).

Among bodybuilders, dosages of regular alone and not rubbed, to prevent the drug from releasing insulin (Humulin-R) used are usually in the range of 1IU into circulation too quickly. It is also advised to rotate per 15-20 pounds of lean bodyweight; 10IU is perhaps the subcutaneous injection sites regularly to avoid the most common dosage. This amount may be adjusted localized buildup of subcutaneous fat due to the downward slightly for users of the more rapid-acting lipogenic properties of this hormone (see Adverse Humalog and Novolog preparations, which provide a Reactions: Lipodystrophy).
