Five classes, one standard of evidence

Anabolic-Androgenic Steroids

Testosterone and its synthetic derivatives — the compounds with the heaviest cardiovascular, hepatic, and hormonal risk.

SARMs

Selective androgen-receptor modulators — mostly research chemicals with limited human safety data.

Peptides

Growth-hormone secretagogues, healing peptides, GLP-1 agonists, and other peptide hormones.

Ancillaries & Support

Aromatase inhibitors, SERMs, gonadotropins, 5-α-reductase inhibitors, and organ-support agents.

PED-Adjacent

Insulin, thyroid hormone, thermogenic stimulants, research chemicals, and cognitive agents.

Some compounds carry outsized danger — lethal hypoglycaemia, hyperthermia with no antidote, severe hepatic or cardiac toxicity. If you read nothing else, read these.
