- A buyer’s guide: how to evaluate a seller and a product
- A method for reading an HPLC / mass-spec certificate of analysis
- Price-per-mg math so you can tell a deal from a warning sign
- A 25-point vendor scorecard you run yourself
- The supply list and the storage rules that protect the purchase
- It does not tell you what to buy, how much to use, or why
- No protocols, no dosing schedules, no medical guidance
- No claim that any compound is safe or effective for any purpose
- Not a “top 10 vendors” list — it names one and teaches the filter
The 11 chapters, in order
The book is built as a funnel: chapters 1–4 teach you to see the market and read the evidence, 5–8 hand you the tools, and 9–11 get you through the order and keep what you bought intact.
- 01The Gray Market, MappedWhat “research-use-only” actually means, the incentive structure you are up against, and why “top 10 vendor” lists are pay-to-play.
- 02The 10 Red FlagsImpossible pricing, COAs with no lot numbers, cloned storefronts, astroturfed reviews, processor churn, no reship policy — and how to use the ten together.
- 03Reading a COA Like a Lab TechWhat a real certificate contains, what ≥98% HPLC purity does and does not mean, the identity check, matching lot numbers, and the tells of a forged COA.
- 04Third-Party TestingThe independent-testing landscape, how to commission your own test, honest cost ranges, and the break-even point where testing pays for itself.
- 05Price BenchmarksNormalize everything to price per milligram, learn the market band before you shop, and know the too-good-to-be-true threshold and why group buys concentrate risk.
- 06The Vendor ScorecardSeven categories, 25 points: COA practice, lot traceability, operating history, payment security, shipping and reship policy, support, community signal — with a fully worked example.
- 07The Vetted ShortlistThe affiliate disclosure sits next to the links, not in the footer. One peptide vendor named, why the list is deliberately that short, and the live page that keeps it current.
- 08Supplies & True Cost of OwnershipBuy commodity, not “peptide-branded”. The shopping list, and the total-cost-of-ownership number most buyers never calculate.
- 09Storage & HandlingLyophilized versus reconstituted, the temperature dial, freeze-thaw, agitation, light, travel — and the storage rules collected in one place.
- 10The Ordering PlaybookThe first-order checklist, the factual reality of domestic versus international, payment-method tradeoffs, and the record-keeping system that makes it all compound.
- 11AppendicesThe frameworks distilled into working tools — print them and keep them with your supplies.
Four printable appendices
A printable sheet with a line for vendor, date and compound. Score each item 1, ½ or 0 across seven categories, then read the total against four bands — plus the two overrides that force a walk-away regardless of score.
Nine checks to run against every certificate before you trust it — lot matching, purity and identity methods, named lab and report number, and the master check: whether the issuing lab will confirm the report at all.
Price per mg = vial price ÷ mg in the vial. How to build a market band from three to five credible sellers, where the too-good-to-be-true floor sits, and the marginal-price math for bulk.
COA, HPLC, LAL, endotoxin, lyophilized, RUO, reship policy — the vocabulary vendors use, defined plainly, so a product page cannot hide behind it.
The disclosure, up front
HighPeptides earns a commission on some of the links in this book — the vendor link, and the supply links on our website that the book points you to — at no extra cost to you. The book says this on page one, next to the links rather than buried in a footer.
What that commission does not buy: the frameworks. The scorecard, the ten red flags and the COA-reading method are the same tools we would hand you if we earned nothing. The book teaches you the filter and then shows you who currently survives it — so you can drop any name in it, ours included, the moment it stops passing.
The living companion to the shortlist chapter: the vendors page · the supply list the book points at: peptide supplies.
Buy the method once, use it on every order
The frameworks do not expire with the shortlist — you re-run them on every order you place after this one. 61 pages, 11 chapters, four printable appendices, PDF and EPUB.

What format is it, and how do I get it?
PDF and EPUB, delivered instantly on purchase through Gumroad. 61 pages, A4.
Does it tell me what to take or how much?
No. It is a buyer’s guide, not a protocol book — it covers vendor evaluation, certificates of analysis, pricing, supplies and storage. It contains no dosing schedules, no protocols and no medical advice.
Is this the same as the Complete Peptide Protocol Guide?
No — different book. The Playbook is about sourcing: vetting a seller, reading a COA, benchmarking price, storing what you bought. Both are listed on the ebooks page.
Will the vendor shortlist go stale?
The shortlist chapter is deliberately paired with a live companion page. When the book and the vendors page disagree, the page is newer — and the 25-point scorecard means you can re-run the judgement yourself on any vendor, at any time.
Are there affiliate links in the book?
The book itself carries no Amazon links — it points back to our own supplies and vendors pages, and those pages carry the affiliate links. It also names one peptide vendor directly. Disclosed in the book and here. The price you pay is the same either way.
Educational purposes only. Not medical advice. This page contains affiliate links — HighPeptides may earn a commission at no extra cost to you.
