How we check prices and FDA records
Today the site shows 2,249 prices from 456 clinics, and 25 compound records built on 238 quotes from the FDA and other sources. This page says how each got here.
What we list, and what we leave out
We list peptide and longevity compounds that a US clinician prescribes and a licensed pharmacy compounds or dispenses: NAD+, sermorelin, BPC-157, glutathione and the rest of the compounds we cover, sold by online clinics that require a prescription.
We leave out sellers of peptides labelled “for research use only” or “not for human consumption”: they sell chemicals with no prescription and no pharmacy behind them. We also leave out GLP-1 weight-loss drugs, hormones such as testosterone, products that blend a compound with a hormone or another drug, and a price a clinic offers only to patients buying another drug from it, since none of these can be set beside the price of a single compound you can buy on its own.
How a price is read
Every price comes from the clinic's own website: never a review site, a coupon site or a figure someone remembers. We save a copy of the page, record the price, what it buys in the clinic's words, the plan length, and a passage from the page that states it. A check then looks for that exact passage and that exact figure in the saved copy, and a price whose passage is not there is dropped.
Each price shows the day it was read. A price not read again in full within 21 days stops counting as current. When a clinic shows the price only after its intake form, or only inside the code of its page rather than as text a visitor sees, we do not list one.
How promo codes and sales are read
A code or a sale is listed only when the clinic states it on its own site: we copy its words, check them against a saved copy of the page, and show the day we read it. We do not take codes from coupon sites and we do not try them at checkout, so a code can stop working before we read the page again; check the total before you pay. A sale is shown until its stated end, or for 10 days after its words were last found on the clinic's page. Every current code and sale.
How prices are compared
Prices are put in order only when they compare: each is brought to 30 days, by the days of supply the clinic states, or else as a monthly bill with its plan length on record. A first-month price, a price per vial with no supply stated, a range and a fee billed apart are listed but not put in order. A different strength, plan or added fee changes what you pay.
Where a clinic offers a plan that can be cancelled any month, that is the price we quote; its longer plans are listed beside it. A monthly price says what it buys where the clinic says so, because one clinic's month of NAD+ can hold half the milligrams of another's.
Where the FDA records come from
Each compound's standing is quoted from the FDA's own pages and documents: its lists of bulk substances for compounding (sections 503A and 503B), its advisory committee records, Drugs@FDA for approved products, its substance registry for what a molecule is where no label says (IGF-1 LR3's length, for one), its warning letters and its recall reports. Where another part of the government acted, as the Department of Health and Human Services did for six peptides in October 2026, we quote that document. Law firms' and trade publications' accounts are used only to find an official record, and where an official record does not exist yet (the committee's vote counts before its minutes are posted) the page says whose account it is.
Every quote was copied word for word from a saved copy of its source and checked against it, and each shows the day it was read and, where the source states it, the day it was last updated. What is our own reading of those records is labelled “Our reading” and kept apart from the facts.
How money touches the order
A clinic cannot buy its way onto this site or change what it says: every price is the one on the clinic's own page, and every regulatory fact is the FDA's. Some clinics pay us when a reader buys through our link, and our default order moves those clinics up; the note under each list says which order it uses, and sorting by price always uses the price alone. We link only to clinics with a referral program, and for the rest we give the price and the clinic's address in words. When we have no source for a figure, we show none.
Some clinics pay us a referral fee when a reader buys through our link; you pay the clinic's own price either way. We link only to clinics that pay us, and for any other clinic we give its price and its address in words. Paying clinics are moved up in our default order, the note under each list says so, and a sort by price uses the price alone. Our order is not medical advice, and the first clinic listed is not necessarily the cheapest or the right one for you.
What the data cannot tell you
- A listed price is not a quote for you. Clinics set the final price after a consultation, and many charge by strength, plan length or state. We show what the clinic publishes and what it says the price buys.
- Monthly prices buy different amounts. One clinic's monthly NAD+ plan may hold half the milligrams of another's. Each price says what it buys where the clinic says it, and only prices billed monthly are set side by side.
- Compounded products are not reviewed by the FDA. No compounded product on this site has been through FDA review for safety, effectiveness or quality, and a pharmacy's name on a clinic's page is the clinic's statement, not ours.
- The FDA's position moves. Several peptides on this site are under FDA review for compounding. Each compound's page quotes the FDA's current words with the day we read them; check that date.
Corrections
If a price, a fact about a clinic or a quote is wrong or out of date, tell us at our email and we read the source again. A clinic cannot pay to change what we show, only to be one we link to.
Changes to how we work
- 14 November 2026: PeptideCompare.co begins. Prices for NAD+, sermorelin and other prescribed peptides, each read on the clinic's own page with a quote of its words, and a page per compound for where it stands with the FDA.
