QUICK ANSWER · AEO / GEO
AAS is a drug class—not a bodybuilding recommendation
Anabolic-androgenic steroids (AAS) include testosterone and derivatives acting through androgen receptors. Esters, formulations and products differ. This page does not endorse any AAS for muscle gain; classification is not a cycle and does not imply interchangeability or safe combination.
01 · IDENTITY MAP
Anabolic steroids grouped by pharmacological identity
Open each Evidence Profile to see whether the record concerns a human medicine, historical use, veterinary agent, experimental compound or regulator warning. Molecule-level evidence does not authenticate any brand, vial or tablet.
Testosterone and esters
Testosterone is the active hormone, but cypionate, enanthate, propionate, undecanoate, no-ester formulations and blends are not one product. Labels, kinetics and authorisation must be checked separately.
19-nor androgen derivatives
These androgen derivatives differ by active moiety and ester. Medical or veterinary history for one compound cannot authenticate another compound or a supplier product.
DHT-derived and oral anabolic steroids
DHT-derived does not mean safe. Many 17-alpha-alkylated oral agents carry material hepatic and lipid risks in addition to suppressing the reproductive hormone axis.
Boldenone-related and other anabolic steroids
This group spans historical medicines, veterinary agents, doping-analysis compounds and experimental substances. Evidence and regulatory status must be read compound by compound.
02 · CATEGORY CORRECTION
Often grouped with steroids—but not anabolic steroids
This distinction matters because mechanisms, harms, contraindications and WADA rules differ. Calling every bodybuilding compound a steroid or stack creates an identity error.
Growth hormone
SARMs / related research compounds
Stimulant / metabolic hazards
Hormone-modifying medicines
These links are included to prevent category errors, not to suggest adjunctive or combined use.
03 · EVIDENCE
What the evidence says about harm—and what it cannot prove
Prohibited at all times
WADA places anabolic agents in S1 and prohibits them in- and out-of-competition, including testosterone, its esters and substances with similar chemical structure or biological effects. The examples are not an exhaustive list.
Serious harm extends beyond the liver
FDA associates steroid or steroid-like bodybuilding products with liver and kidney injury, heart attack, stroke, blood clots, mood effects, sexual dysfunction, testicular shrinkage and infertility.
A label does not prove composition
Online or supplement products may contain undeclared steroids, SARMs or other drugs. A molecule Evidence Profile cannot verify the identity, amount, purity or sterility of a real-world product.
04 · SAFETY BOUNDARY
Major risk domains
Hypertension, adverse lipids, erythrocytosis, cardiomyopathy, myocardial infarction, stroke and thrombosis
Cholestatic or hepatocellular injury—especially with many 17-alpha-alkylated oral agents—plus kidney injury and multi-product uncertainty
Gonadotropin and endogenous hormone/sperm suppression, testicular atrophy, infertility, gynecomastia and potentially irreversible virilisation in women
Mood change, aggression, depression, acne and hair loss, plus mislabelled, counterfeit, contaminated or non-sterile products
Combining drugs does not neutralise risk
FDA notes that multi-product use makes attribution difficult and may add interaction risk. This guide therefore gives no cycle, stack, dose, preparation or injection instructions.

Frequently asked questions
What does bodybuilding steroid mean?
It usually means an anabolic-androgenic steroid, not a corticosteroid. Appearance in bodybuilding culture is not an approved indication.
Are testosterone cypionate, enanthate and propionate the same?
They yield testosterone after ester cleavage, but ester, formulation, label and pharmacokinetics differ. They are not one product and authorisation cannot be transferred.
Is trenbolone an approved human medicine?
No FDA-approved human trenbolone product was identified in the reviewed sources. Veterinary history or an ester name does not establish human safety.
Are oral steroids safer?
No. Avoiding injection does not remove systemic risk, and many 17-alpha-alkylated oral agents carry material hepatic and lipid risks.
Are HGH, SARMs and clenbuterol steroids?
No. HGH is a peptide hormone, SARMs are a separate modulator class, and clenbuterol is a beta-2 agonist.
Is there a safe steroid cycle?
This page establishes no safe cycle. Combining compounds does not cancel harms and can make causality harder to determine.
Can athletes use anabolic steroids?
WADA 2026 prohibits anabolic agents at all times. Exact-product medical use requires the formal TUE process when criteria are met.
Does PrimeCoreBio provide doses, cycles or administration instructions?
No. The scope is identity, evidence, risks, regulation and traceable educational sources.
