Performance-enhancing drugs

An honest, harm-first reference on the drugs used to change how the body performs and looks — anabolic steroids, SARMs, and the ancillary and metabolic agents that travel with them. What each one is, where it stands with the law, what the evidence actually shows, and the real risks.

What this is, and isn’t

This is a library that explains these compounds — what they are and what they do to the body. It is not a how-to. You will find no doses, no cycles, no protocols and no sources here, deliberately and permanently. The most useful thing on any of these pages is the same: if you use or are considering these substances, involve a doctor and monitor your blood work.

Injectable anabolic-androgenic steroids

  • Testosterone (esters)Gold· human data

    The natural male androgen; injected esters are the reference anabolic steroid all others are measured against.

  • NandroloneGold· human data

    The 'deca' steroid, known in gyms for joint comfort claims and for one of the longest detection windows of any compound.

  • TrenboloneBronze· animal data only

    A very potent androgen developed for livestock, never licensed for humans, with a side-effect reputation as strong as its anabolic one.

  • BoldenoneBronze· animal data only

    The 'EQ' steroid: a veterinary androgen used for slow lean gains, with almost no human evidence behind its reputation.

  • DrostanoloneSilver· human data

    The 'masteron' steroid: a DHT-derived androgen used cosmetically at low body fat, with an effect that is largely visual.

  • MethenoloneSilver· human data

    The 'primobolan' steroid: a mild androgen with one of the largest reputation-to-evidence gaps in this library.

Oral anabolic-androgenic steroids

  • OxandroloneGold· human data

    A mild oral steroid with a reputation for lean gains, but an oral 17-alpha-alkylated compound, with the liver cost that carries.

  • OxymetholoneGold· human data

    The 'anadrol' steroid: one of the strongest orals available, and one of the hardest on the liver and blood pressure.

  • MethandrostenoloneGold· human data

    The 'dianabol' steroid: the original performance oral, and still one of the harder ones on the liver.

  • StanozololGold· human data

    The 'winstrol' steroid: the compound of the Ben Johnson scandal, known for joint dryness and severe lipid harm.

  • TurinabolSilver· human data

    An oral steroid built for the East German state doping programme, with a notoriously long detection window.

  • FluoxymesteroneSilver· human data

    The 'halotestin' steroid: an extremely strong androgen with one of the worst safety profiles in this library.

  • MesteroloneSilver· human data

    The 'proviron' compound: a weak oral androgen used more as a supporting drug than as a muscle builder.

SARMs & non-steroidal anabolics

  • Ostarine (MK-2866)Silver· human data

    The best-known SARM, sold as a 'lighter' steroid alternative, but unlicensed, unregulated in what's actually in the bottle, and not the clean option it's marketed as.

  • Ligandrol (LGD-4033)Silver· human data

    One of the more potent SARMs: unlicensed, clearly suppressive, and among the most frequently mislabelled products sold.

  • Testolone (RAD-140)Bronze· animal data only

    A strong SARM with early safety signals including serious liver injury: unlicensed, and abandoned in clinical development.

  • Andarine (S4)Bronze· animal data only

    An older SARM best known for a distinctive visual side effect: unlicensed, and abandoned in development.

  • Cardarine (GW-501516)Not supported· animal data only

    Sold alongside SARMs but not one: a metabolic drug abandoned in development after animal studies found cancer across multiple organs.

  • Stenabolic (SR9009)Unproven· animal data only

    A research compound sold as a SARM that it isn't, with a marketing story built on mouse studies and a fatal flaw in how it is taken.

Ancillaries & post-cycle drugs

  • AnastrozoleGold· human data

    A breast-cancer medicine that appears in this context to lower oestrogen: covered for what it is and why it turns up, not how it is used.

  • TamoxifenGold· human data

    A breast-cancer medicine that appears in this context as a post-cycle drug; educational coverage only.

  • ClomifeneGold· human data

    A fertility medicine that appears in this context around restarting suppressed hormone production; educational coverage only.

  • hCGGold· human data

    A genuine fertility hormone that appears in this context around suppressed natural production, and separately in a discredited diet.

Metabolic & fat-loss agents

  • ClenbuterolSilver· human data

    A bronchodilator misused for fat loss, with a modest effect and a genuine cardiac risk that scales with it.

  • Liothyronine (T3)Gold· human data

    A real thyroid medicine misused for fat loss, which suppresses your own thyroid function and costs muscle as well as fat.

  • Licensed prescription medicines with strong trial evidence: included here because they are misused outside that, not because they belong with the rest.

  • DNP (2,4-dinitrophenol)Not supported· human data

    Not a medicine and not a supplement: an industrial poison that has killed people, covered here to warn without ambiguity.

Growth hormone & peptides

  • Growth hormone (hGH) & IGF-1Silver· human data

    A prescription hormone with a real medical role and a physique reputation that the human evidence does not support.
