Anabolic Steroids & Performance-Enhancing Drugs

MESO-Rx is the authoritative source for information about anabolic steroids and performance-enhancing drugs. Learn about the history of steroids, how anabolic steroids work, how to use steroids for enhanced muscle size, strength and performance, how to prevent steroid side effects, how steroids are used in testosterone replacement therapy and reviews of steroid sources. The website advocates an intelligent and rational discussion of the medical and non-medical uses of steroids and performance-enhancing drugs.

Use of Boldenone Undeclyenate for “Enhanced” Hormone Replacement Therapy (HRT)

The Use of a Single Anabolic Steroid for “Enhanced” Hormone Replacement Therapy (HRT)

Q: “I want to use the minimum number of drugs for an “enhanced” hormone replacement therapy (HRT) protocol. I’d prefer really to use only one drug. I could use testosterone, but if I do that, then I can’t use very much without putting my estradiol higher than I want to. Letrozole won’t work for me, […]

Use of Insulin Without Getting Fat

The Use of Insulin Without Getting Fat During a “Cutting” Steroid Cycle

Q: “I’ve tried insulin use on and off and though I think it helped my muscle gain in steroid cycles, it also got me fat. How might I use insulin when doing a cutting cycle, or even harder, a body-recomposition cycle?” A: One of the most interesting and creative ergogenic ideas ever published, I think, […]

Long-Term Use of Melanotan II for Tanning

The Long-Term Use of Melanotan II for Tanning

Q: “I’ve found a fair bit of information on short-term use of Melanotan II (MT-II) but nothing on long-term use. I’ve never been able to stay out in the sun as long as I’d like, and have never been able to get a really good tan. But I’m not interested in a temporary fix. How […]

Stacking Deca Durabolin With Peptides TB-500 and/or GHRP-6 to Promote Healing

Stacking Deca Durabolin With Peptides TB-500 and/or GHRP-6 to Promote Healing

Q: “I’m planning to use TB-500 and/or GHRP-6 in a cycle which I hope will heal some of my injuries. Ideally would I do this only as a peptide cycle, or would I include one or more anabolic steroids?” A: As much as I’m generally not a fan of nandrolone (Deca Durabolin) because of frequently seen […]

The Stacking of GHRH (CJC-1295) and GHRP Peptides to Stimulate Growth Hormone Release

The Stacking of CJC-1295 and GHRP Peptides to Stimulate Growth Hormone Release

Q: “If using peptides instead of hGH, can I combine a growth hormone releasing hormone (GHRH) like CJC-1295 with a GHRP? When might it be better to use just the GHRP, versus using the combination?” A: Growth hormone releasing hormone (GHRH) is a natural hormone which works synergistically with ghrelin to stimulate pulses of GH […]

hGH plus GHRP-6 or TB-500 for a Healing Cycle

The Stacking of TB-500 with GHRP-6 or hGH for a Healing Cycle

Q: “For a healing cycle, can I combine TB-500 with GHRP-6, or with hGH? Can I just use the same doses of each as I normally would, or should doses be reduced because they are being combined? And can I use anabolic steroids concurrently with TB-500?” A: Absolutely TB-500 can be combined with GHRP-6 or GH. […]

Human growth hormone (hGH) stacked with GHRP-6 for healing

The Stacking of GHRP with hGH for a Healing Cycle

Q: “For a healing cycle, should I combine a growth-hormone releasing peptide (GHRP) with hGH?” A: Usually, no. The exception would be if your preference is for high-dose GH use and you personally can tolerate such doses, which most cannot. A GHRP, for example GHRP-6 at 150-200 mcg 3x/day, often already provides about as much GH […]

GHRP-6 with TB-500 and Deca Durabolin

hGH vs. GHRP: Which is Better for Muscle Growth and/or Healing?

Q: “I can afford to do either a moderate cycle of human growth hormone (hGH) or of a growth hormone releasing peptide (GHRP). I like the idea of using a GHRP to stimulate my own growth hormone production, rather than getting hGH out of a needle. I’m mostly trying to keep my body functioning well, […]

TB-500 (thymosin beta-4)

The Use of TB-500 to Treat Injuries and Improve Healing Rate

Q: “I’m interested in TB-500. A few times I’ve used GH to treat injuries, and it seemed like healing rate was improved. But now I have chronic forearm tendinitis which isn’t going away. It’s interfering with my lifting. If GH is helping this time, it’s not helping enough. Also, my dad has chronic muscle tightness […]

“Clean Bulk” versus “Dirty Bulk” Diet During Steroid Cycle

“Clean Bulk” versus “Dirty Bulk” Diet During Steroid Cycle

Q: “What dietary changes should I make for a ‘clean-bulking’ steroid cycle? Or should I just go for a ‘dirty bulk’ and diet the blubber off later?” A: While a caloric excess definitely is needed for fastest gains, there’s no need to pack on fat rapidly. There doesn’t seem much difference in gains between eating […]

Steroid Site Injections for Increasing Muscle Size

Steroid Site Injections for Increasing Muscle Size

Q: “Does site injection work? How do I do it?” A: Particularly in small muscles, there can be a substantial increase in size from site injection. The improvement can last for months since the last injection. It seems unlikely that the reason is increased action at the muscle of the injected steroid. Instead, the benefit […]

Long-Term Use of Clomid or Nolvadex to Increase Testosterone Levels

Long-Term Use of Clomid or Nolvadex to Increase Testosterone Levels

Q: “My T levels are low-normal and for me there’s a drastic life quality difference when I use even small amounts of testosterone. Instead of injecting testosterone every week for the rest of my life, could I use Clomid or Nolvadex instead? When I’ve used Clomid post-cycle I had great results and felt much better. […]

Using SARMs During Steroid Cycles or During PCT

The Use of SARMs During Steroid Cycles or PCT

Q: “How should I incorporate SARMs (selective androgen receptor modulators) into my steroid cycle or into PCT?” You should not do so. Various authors in the scientific literature have tried to make it appear that in contrast to anabolic steroids, SARMs somehow will have an improved side effect profile or an increase in dissociation between […]

Using Therapeutic Steroid Dosages for Building Muscle

The Use of Therapeutic Steroid Dosages for Building Muscle

Q: “I’m 23 and interested in getting an edge with anabolic steroids, but have no professional aspirations either as an athlete or bodybuilder. I just want to be moderately bigger and stronger (I already lift heavy and consistent.) I don’t see why I need doses like theirs or why I’d need to shock my system […]
