How we assess

Nature of reviews

A seller review here is a close reading of what the seller charges and on what terms. It is not a clinical judgment, and it is not a test purchase.

What a review covers

A review starts with the seller’s price page and follows every fee it mentions, including the membership, the consult, shipping, and whatever the plan requires you to prepay. It then records which peptides and forms the seller offers, which states it serves, and how the price behaves as a dose changes. The result is the all-in monthly figure described in how we price, plus the terms a buyer would want to know before signing up.

What it does not cover

A review does not say whether a peptide will work for you, and it does not rate the care a clinician gives. Those are medical questions, and nobody on this site is qualified to answer them for you. It also does not come from a checkout: no price on this site was verified by completing a purchase, so a seller’s cart can still show something the price page did not.

When a seller gets named

Market figures, meaning the typical, low and high price for each peptide, count every seller that publishes a monthly price, reviewed or not. A seller’s name only appears on a price board once we have written our own review of it, so that every named row carries a reading of its fees and terms rather than a bare number copied from somewhere. 12 sellers have reached that point so far.

Peptides we never price

Some sellers list peptides that the FDA has neither approved nor allowed to be compounded, such as BPC-157. We never price those or link to them, even when they appear on a seller we review. The list of what can and cannot be priced is on how we price, with the date each status was read from FDA documents.

How a partnership shows up

12 reviewed sellers pay us a commission today. Their links carry a Partner label. Where sellers are listed together by price, a partner keeps its place in the price order. The price in their reviews goes through the same fee arithmetic as every other seller’s.

A partnership cannot change a seller’s price, its corrections, or its score. Prices and corrections follow the same arithmetic for every seller, and the function that computes a score does not receive commercial status as an input. The full account of the money is on disclosures.

Sellers who pay us nothing

A seller with no commercial relationship with us is reviewed the same way, against the same fee arithmetic. Its link takes you to its own site and earns us nothing. When a partner sells the same peptide, clicking that link may first show that partner as an alternative, labeled as one we earn on, with a link to continue to the seller you chose. It is covered because readers are choosing between it and the others, and its prices count toward the market figures exactly as a partner’s would.

When a review goes stale

Sellers change prices and plans without announcing it, so every figure in a review carries the date it was read. If what you see on a seller’s site no longer matches, send the page to rates@buythispeptide.com, and the corrections policy explains what happens next.
