Is Peptide Pro legit?
Peptide Pro scores 5.62 out of 10 (Fair, tied #65 of 100) as of November 6, 2026 and passes our testing gate: 42 of the 43 products we score carry a certificate, 33 confirmed with the issuing lab (labs we grade A to A-). Its strongest area is lab testing (6.0/10); its weakest is operating history (3.1/10), with over a year of records. We also record that nine posted certificates differ from the laboratory's own copy and some of its certificates were issued to another business.
On lab evidence, the heaviest-weighted factor, Peptide Pro has independently verified third-party COAs, with COA work on record from Bioviridian, Horizon Analytical, Freedom Diagnostics Testing. Its lowest price per milligram in our data is on Glutathione (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 27, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility6.0/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Testing gate: 33 of 43 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is at least half, so the vendor counts as third-party tested and no cap applies.

Pricing5.4/10
We compared Peptide Pro’s current single-vial prices on 38 products, each matched to the same product and milligrams per vial, with the median price of the other vendors. Its typical price (the median ratio across those products) is 22% above the market median (ratio 1.22), which the published scale maps to 5.4/10. checked
Operating history3.1/10
Counted from December 22, 2024, the earliest dated evidence of this business operating: 22.1 months as of October 27, 2026, which the published table maps to 3.1/10.
Domain peptidepro.io registered 2024-09-25 (RDAP). The first archived captures (2024-09-30, a redirect; 2024-11-18, a server error) do not show what the domain carried, so the registration date alone is not counted. The earliest record of the business operating is an archived copy of the store from 2024-12-22 (shop, product categories and cart). Later records: Freedom Diagnostics certificates issued to Peptide Pro from June 2025. The privacy policy names Biotech Nutra Inc.

The 'Fire Sale: 60% off select peptides' is applied as code FIRE60 at checkout (a named promotion applied as a code), so it is not counted (rule E). Struck-through 'Original price' figures appear only on multi-product bundles, which are not priced. The first-order discount code, Gold/VIP membership discounts and loyalty points are not counted.
- Pricing: MK-677, tesofensine and SLU-PP-332 are sold only as capsule bottles and are not priced; 5-amino-1MQ and GHK-Cu are priced on their vials, and their capsule versions are not priced. Multi-product bundles and stacks are not priced.
- Lab: nine posted certificate copies (eight Horizon Analytical reports and one Bioviridian report) print dates that differ from the laboratory's own copy and score 0 under rule A4; the laboratory records were found in every case.
- Lab evidence: on 3 November 2026 the sermorelin certificate (Freedom Diagnostics, reported 2 November 2025) was re-confirmed at the laboratory and passed 12 months, so the A6 age deduction now covers it and the lab subscore moved from 6.1 to 6.0. The certificate index is behind sign-in and was not re-read for a newer report.

Audit history and why the rating changed
We re-audit vendors against their live COAs and site. Here is what most recently moved this rating, and why.

- Most recent audit · 5.63to5.62
Pricing re-checked on 6 November 2026 after the market medians were recalculated with GhostLabz and NextSelf Labs added pricing 5.5 to 5.4.
- Audit · 5.69to5.63
Lab evidence re-checked on 3 November 2026. The sermorelin certificate (Freedom Diagnostics, reported 2 November 2025) passed 12 months old and is the newest one on record for that product, so under the published age rule (A6) it now counts as an older certificate. The certificate itself was re-confirmed at the laboratory. Lab evidence 6.1 to 6.0.

lab 6.1 / shipping 5.5 / pricing 5.6 / tenure 3.1 / transparency 5.0. First audit after the vendor's submission, read through a signed-in account (rule F3). 42 of 43 catalogue products have a certificate and every scored certificate was found at the issuing laboratory (Bioviridian, Freedom Diagnostics Testing, Horizon Analytical). Nine posted copies differ from the laboratory's copy in their dates (rule A4, scored 0); a lot label repeats across compounds (A7 LOT, -0.2); ten Horizon reports repeat analyses first issued to another business (A7 SUPPLIER, -0.2); the home page purity statement is not borne out by two posted reports (A7 CLAIM, -0.1).
Editor’s notes
Peptide Pro sells research peptides from peptidepro.io and ships within the United States. The whole site, including the catalogue, prices, certificates and policy pages, is shown only to signed-in customers, and we read it through an account (rule F3). Most products are sold as single vials; MK-677, tesofensine and SLU-PP-332 are sold only as capsule bottles and are not priced. The store's certificate index lists 76 entries from Bioviridian, Freedom Diagnostics Testing and Horizon Analytical. Of the 43 catalogue products we list, 42 have a certificate; GHRP-6 has none. We scored the newest certificate for each product and found every one at the issuing laboratory. For eight products (BPC-157, TB-500, selank, melanotan II, NAD+, KPV, DSIP and oxytocin) the newest certificate is a Horizon Analytical report whose posted copy prints a received date of 10 June 2026 and an analysis date of 11 June 2026, while the laboratory's record and its own copy give an analysis date of 5 June 2026; for follistatin 344, the posted Bioviridian copy prints dates one day later than the laboratory's copy and a different sample type. Those nine certificates score 0 under rule A4. Ten of the twelve Horizon reports the store posts carry the same lot numbers, results and chromatogram images as Horizon reports issued earlier to another business. Separately, on Bioviridian certificates the same lot label, including RRV-110125 and RETA60-101626, is printed for different compounds. Purity on the scored certificates runs from 99.06% to 99.9%, and the home page states that every peptide is tested to 99% or higher, while two posted Freedom Diagnostics reports for current products read 98.4% and 98.5%. Retatrutide, tirzepatide and semaglutide are sold as 'RTA GLP-1', 'TRZ GLP-1' and 'SMA GLP-1', and their pages do not name the compound. Orders ship within 2 business days by the shipping policy (the FAQ says 2 to 3), with tracking emailed and free shipping above an order minimum. All sales are final apart from incorrect items reported within 7 days, and lost or damaged parcels are covered only by an optional paid insurance. The FAQ says international shipping is available while the shipping policy says the store ships only within the contiguous United States. The checkout offers a card gateway. The privacy policy names Biotech Nutra Inc. and a suite and box number in Franklin, Tennessee, and the contact page gives a phone number; no person is named, and the terms name Tennessee law but carry no date. The earliest record of the store operating is an archived copy of the shop from 22 December 2024, and its operating history is counted from then.
