Peptide Pros has been selling online since 2013, which makes it one of the longer-running names in a market where storefronts routinely appear and vanish within a year. The company lists Miami Beach, Florida as its headquarters, ships from a facility in Colorado by USPS, and sells lyophilized vials, blends and bulk quantities alongside a second line of liquid research chemicals. The one thing a reader should know before anything else is that the public testing record stops in 2023. Everything that follows comes back to that date.
We read the homepage, the BPC-157 product page, the COA reports page and one of its PDFs, the FAQ, the delivery-guarantee page and the Trustpilot profile, then searched the FDA warning-letter database. Thirteen years of operation is a fact in the company’s favor, but age is not evidence of quality, so we treated every statement on the site as a claim to be checked against the documents the company itself publishes.
The claims this storefront makes
The storefront’s central promise is a purity guarantee: products are “guaranteed above 99% purity or replaced free.” Next to it sits a Delivery Guarantee, which promises a free reship if a package never arrives, once a buyer has allowed 14 days for domestic orders or 45 for international ones. The testing claim is that products are tested by MZ Biolabs, with certificates of analysis on a public page. The logistics claims are that most orders ship the same day, that orders placed after 12pm EST ship the next day except on Sundays, and that every order is processed within 24 hours. The site also quotes review totals in several places, and those totals do not agree with one another: 16,000+, 17,900 and almost 4,200.
No certifications are claimed. The company does not call itself GMP or ISO anything, which at least means there is nothing of that kind to overstate.
What held up when we checked
The certificate page is open to anyone and the documents on it are genuine lab reports, not marketing graphics. Each carries a lot number; the BPC-157 5 mg report is for lot AF98762213, and a CJC-1295 report covers lot AF21220321. They name MZ Biolabs of Tucson, Arizona as the testing laboratory and report mass spectrometry and UV purity. A named lab, a lot number and a method is the minimum we look for, and Peptide Pros clears it.
The commercial terms are documented in detail. Payment can be made by card, e-check or ACH, Bitcoin, mailed check and bank wire, which is a wider set of options than most competitors offer and includes the card payments some buyers want for chargeback protection. United States priority shipping is free above $150, dispatch is from Colorado by USPS, and the company ships internationally. A toll-free number, 1-888-391-1312, is published, and a research-use-only disclaimer is present.
Pricing lands in the middle of the market. The 5 mg BPC 157 vial is $47.25 against a list price of $56.60, TB-500 2 mg is $37.25, Sermorelin and Ipamorelin at 2 mg are $23.99 each, and a 500 mg NAD+ listing is $149.95. The after-delivery policy is more generous than most: if a package fails to arrive twice, the company offers a final reship or a refund minus shipping and 20 percent.
What did not hold up, and what we could not verify
The purity guarantee is a statement about the vial a buyer receives today. The certificates describe vials from two or three years ago. The public page holds about 21 reports dated 2021 to 2023, under a banner reading “MORE DATA COMING SOON,” and nothing more recent appears. The BPC-157 product page links to no certificate for the lot currently on sale. A 2023 report cannot verify a 2026 vial, so until the page is refreshed the guarantee is a promise rather than a document. Endotoxin and sterility testing are not mentioned anywhere.
The review figures cannot be reconciled with anything. The site quotes three different totals, and Trustpilot, the one platform we can check independently, has removed the company’s profile for going against its guidelines. We do not know what the on-site numbers count or where they come from.
The certificate page also previously listed 2023 reports for two GLP-class products, while the homepage shows no GLP-class listings today. Either the catalog changed and the page was not updated, or the page is stale in other ways too; the record does not tell us which. Separately, the catalog mixes peptides with liquid SARMs and PDE5 and SERM research chemicals. We note that as a business-practice observation: mixed research-chemical catalogs tend to draw more regulatory attention than peptide-only ones.
Several basics are missing. No email address and no street address are published, so the Miami Beach headquarters cannot be confirmed from the site itself, and the approximate product count is unknown. Returns and refunds on products are not accepted, which the company attributes to health and safety reasons; the only remedy is replacement for product testing below 99 percent. No FDA warning letter naming Peptide Pros was found as of October 19, 2026, and Finnrick, an independent testing aggregator, has no entries for this supplier in our record, so there is no outside test data to weigh.
Our read
Peptide Pros reads like a real, durable business with a real laboratory relationship that it stopped showing in public three years ago. Everything we could check about ordering, paying and shipping was consistent and reasonably buyer-friendly, and the breadth of payment options is a genuine advantage. The weakness is concentrated in one place, and it is the place that matters most: the certificates do not reach the products on sale. For a buyer who values a long operating history, card payment and a delivery guarantee, and who intends to test what arrives, this is a workable supplier. For a buyer who needs a current, lot-matched certificate before ordering, the site does not provide one, and we would not take the 99 percent guarantee as a substitute.
