The Book of Peptides is not a clinic and not your doctor. We do not sell, prescribe, recommend, or personalize any compound, and no grade or ranking here is an endorsement. None of the compounds covered are approved for the uses described here by the U.S. FDA, Australia's Therapeutic Goods Administration (TGA), New Zealand's Medsafe, or the equivalent regulator in most other countries.
Most are sold for laboratory research only, a few are prescription-only drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful wherever you live. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.
Cross-checked against 50–100 independent sources per claim — the house standard. How this reference is checked
Reference values as published in the research record — not a recommendation, instruction, or dose suggestion for any person. Not medical advice.
Not reconstituted — vials delivery, so there's no vial to draw from.
Not a secretagogue but the section's target itself — recombinant 191-amino-acid human growth hormone, the molecule everything else here exists to release. Grey-market kits dose in IU (the WHO standard assigns ~3 IU/mg); approved labels dose in mg only. The FDA adult label starts at roughly 0.2 mg/day (~0.6 IU), raised every 1-2 months against serum IGF-1; AACE/ACE guidelines start lower with diabetes, obesity or older age — labeling warns somatropin decreases insulin sensitivity.
The member edition is the full write-up: every claim cross-checked against independent sources and challenged before print. What didn't survive the check isn't in here.
The full published spec sheet — dose units, timing, frequency, and cycle length — is included with membership.
The published start, titration steps, and target dose, shown as reference. Included with membership.
