The newsletter

We read the enforcement feeds so you don't have to — and link the source, not our spin.

Only when there's something worth sending — often nothing for a week. Unsubscribe any time.

Not medical advice

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.

Before you subscribe
Can I cancel anytime?+

Yes — from Manage billing on your account page, in a couple of taps. Access runs to the end of whatever period you've paid for, and nothing renews after that.

What exactly unlocks?+

Everything listed above, on both plans — the two rates unlock identical access. There are no tiers, add-ons, or per-book charges behind the membership.

Does it work on my phone?+

The whole site is built for it — the reader, the calculators, and the Dirty Secrets file all run in the browser on phone, tablet, or desktop. Nothing to install.

Prefer to just own a copy? Buy any book, the three-book bundle, or the complete set, as a PDF — once, with no subscription.
