Soluble activin type IIB receptor fusion protein designed to trap myostatin/activin ligands and increase muscle mass; clinical development halted after safety signals.

Full-length adrenocorticotropic hormone peptide used in endocrine and stress-axis research; parent pathway for several nootropic ACTH analogs.

Cell-permeable AMPK-activating nucleoside analog famously studied as an exercise mimetic in sedentary mice; WADA-prohibited.

GHRH analog that stimulates natural growth-hormone pulses; used with GHRPs for body composition and recovery goals.

The default growth-hormone peptide stack in biohacking: GHRH analog + selective GHRP for physiologic pulses.

Long-acting GHRH analogue form of CJC-1295 using Drug Affinity Complex for multi-day GH/IGF-1 elevation research framing.

Extremely potent natural mu-opioid heptapeptide from South American frog skin; research and forensic interest due to analgesic potency far exceeding morphine.

Myostatin-pathway related protein/peptide product marketed for extreme muscle growth; high risk, poor quality control.

Endogenous negative regulator of skeletal muscle growth; catalog material is typically for assay/research reference rather than use as a drug.

Potent GH-releasing peptide; stronger hunger and prolactin/cortisol effects than Ipamorelin.

Early GHRP known for intense appetite stimulation; used when hunger and GH pulse are both desired.

Synthetic gonadotropin-releasing hormone used to stimulate pituitary LH/FSH release; research and diagnostic endocrine applications.

Glycoprotein hormone used in fertility and TRT adjunct settings; endocrine staple in men’s health clinics.

Very potent GHRP with notable GH output but higher desensitization and cortisol/prolactin risk.

Recombinant human growth hormone (191 amino acids) — pharmaceutical somatropin exists for approved deficiency indications; research vials are a separate gray-market category.

Urinary-derived or recombinant mixture of FSH and LH activity used in fertility medicine to stimulate gonadal function.

Long-acting IGF-1 analog used in bodybuilding research circles for hypertrophy; significant risk profile.

Foundational peptide hormone for glucose control; abused in bodybuilding — extremely dangerous without medical need.

Selective ghrelin-receptor (GHS-R) agonist that stimulates GH with relatively clean side-effect profile among GHRPs.

Peptide that stimulates GnRH release; researched for reproductive endocrinology and low-libido / low-T workups.

Quaternary ammonium compound that shuttles long-chain fatty acids into mitochondria for β-oxidation; injectable and oral forms used in metabolic and sports contexts.

Splice variant of IGF-1 expressed in response to mechanical overload; researched for localized muscle repair. Short half-life; PEGylated MGF is the stabilized catalog cousin.

Pegylated mechano growth factor variant discussed for muscle repair; evidence mostly anecdotal/preclinical.

Experimental ERR agonist exercise-mimetic small molecule trending in biohacking; not a peptide.

Synthetic peptide related to thymosin beta-4, used in recovery communities for systemic tissue repair and flexibility.

Long-acting GnRH superagonist that initially stimulates then downregulates pituitary gonadotropin release; used medically for hormone-dependent conditions.

Community name for combining BPC-157 and TB-500 for soft-tissue and systemic recovery.
