Questions
Frequently asked.
The short version of how access, formats, and our sourcing actually work. Still stuck? Everything links out to the full page.
What's the difference between membership and the eBooks?
Membership unlocks the whole reference as a live app — the complete online reader for all three books, every compound's evidence tier, published dosing protocol, and sourced write-up, plus reconstitution calculators and the by-country newsletter. The eBooks are the individual books as downloadable PDFs: great for reading, but without the interactive calculators. See membership or the books.
What formats do the books come in?
Two. With membership you read everything in the interactive online reader. Buy an eBook and you get a print-quality PDF download — any single book, or the whole trilogy as a bundle. Both are the same fact-checked content; only the reading experience differs.
Do you offer refunds?
Because books and membership are digital and access is granted the moment you buy, we generally can't offer refunds once you've downloaded a PDF or opened the reader. If something isn't working or you were charged in error, head to your account or get in touch and we'll make it right.
Is any of this medical advice?
No. The Book of Peptides is an educational, harm-reduction reference for people already engaging with these compounds. It is not medical advice and not a substitute for a qualified clinician who knows your history. None of the compounds covered are approved for these uses by the FDA, TGA, Medsafe, or your own country's regulator — see our terms for the full disclosure. More on that in about.
How do you know the dosing and claims are right?
Every dosing and scheduling claim is cross-referenced across 50–100 independent sources, then put through an adversarial pass built to refute it — not confirm it. Only claims that survive get published; the rest are deleted, not repeated. The full method is on our methodology page.
Which countries can access this? And what's the newsletter?
It's all digital, so you can read it anywhere. The membership newsletter tracks the latest peptide developments organised by country, so what lands in your inbox is relevant to where you are. See the newsletter.
How do I read online versus on PDF?
Members read in the browser — open the online reader and everything's there, cross-linked and searchable. eBook buyers download their PDF from their account after purchase and read it however they like, offline included.
Do I need an account, and how do I get back in?
Not to buy a book — check out as a guest and your download links land on the confirmation page and in your inbox. An account is only needed for membership (the online reader) or if you want your book purchases saved to a library for easy re-download later; creating one afterwards is offered, not required. Already have one? Just log in to pick up the reader or manage everything from your account.
Can I buy one book now and add membership later?
Absolutely. Start with a single book or the bundle, and upgrade to full interactive membership whenever you want the calculators and online reader — it's a separate option on the membership page.
What do you do with my information?
Only what's needed to run your account, deliver what you bought, and send the newsletter you opted into. The specifics live in our privacy policy and terms.
