Know what you're running.
A plain-English reference for the compounds and peptides people actually use — what each is, the context it's used in, half-lives, and how to handle it. Educational only, not medical advice.
GLP-1 / incretin
Semaglutide
Ozempic, Wegovy
A long-acting GLP-1 receptor agonist used for appetite regulation and weight management.
Tirzepatide
Mounjaro, Zepbound
A dual GIP/GLP-1 receptor agonist — often stronger appetite effect than GLP-1 alone.
Retatrutide
An investigational triple agonist (GIP/GLP-1/glucagon) still in trials.
Peptide
BPC-157
Body Protection Compound-157
A synthetic peptide popular in the recovery/healing context.
TB-500
Thymosin Beta-4 fragment
A peptide associated with the actin-regulating protein thymosin beta-4, used in recovery contexts.
Ipamorelin
A selective growth-hormone secretagogue (ghrelin-receptor agonist).
CJC-1295
with or without DAC
A growth-hormone-releasing hormone (GHRH) analog, often stacked with a secretagogue.
GHK-Cu
Copper peptide
A copper-binding peptide used in skin/hair and recovery contexts.
PT-141
Bremelanotide
A melanocortin-receptor agonist used for libido/sexual function.
Melanotan II
MT-2
A melanocortin agonist used for tanning; also affects libido and appetite.
MK-677
Ibutamoren
An orally-active growth-hormone secretagogue (not injected).
Anabolic-androgenic steroid
Testosterone
Cypionate / Enanthate / Propionate
The base androgen; ester length sets how often it is injected.
Nandrolone
Deca-Durabolin (decanoate), NPP (phenylpropionate)
A 19-nor anabolic; "Deca" is long-ester, "NPP" is short-ester.
Trenbolone
Tren Acetate / Enanthate
A potent 19-nor androgen; acetate is short-ester, enanthate longer.
Drostanolone
Masteron
A DHT-derived androgen used mostly in lean/finishing contexts.
Boldenone
Equipoise (EQ)
A long-acting anabolic known for a slow, steady build.
Oxandrolone
Anavar
A mild oral DHT-derivative valued for lean, dry gains.
Methandrostenolone
Dianabol, Dbol
A fast-acting oral known for rapid mass and water retention.
Stanozolol
Winstrol
A DHT-derived compound (oral or injectable) used for a dry, hard look.
Ancillary / support
HCG
Human chorionic gonadotropin
Mimics LH to maintain testicular function during androgen use.
Anastrozole
Arimidex (an AI)
An aromatase inhibitor that lowers estrogen.
Enclomiphene
a SERM
A selective estrogen receptor modulator that raises natural LH/FSH and testosterone.
Exemestane
Aromasin (an AI)
A steroidal aromatase inhibitor that lowers estrogen and binds irreversibly.
Clomiphene
Clomid (a SERM)
A SERM used to restart natural testosterone, often in PCT.
