Is Hacker Peptides legit?
Hacker Peptides scores 6.32 out of 10 (Fair, #53 of 100) as of November 2, 2026 and passes our testing gate: 11 of the 13 products we score carry a certificate, 11 confirmed with the issuing lab (a lab we grade A). Its strongest area is pricing (9.5/10); its weakest is operating history (2.3/10), with over a year of records.
On lab evidence, the heaviest-weighted factor, Hacker Peptides has independently verified third-party COAs, with COA work on record from Freedom Diagnostics Testing. We hold 16 lot certificates in all. 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 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility6.5/10
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: 11 of 13 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.

Returns and refunds
Hacker Peptides does not accept returns or exchanges once an order has been processed and shipped. ... For those reasons, all sales are final. ... (damaged or incorrect) We will compare the shipment with the order record and explain the next step.
Re-check of 2 November 2026 (re-audit #29): all sales are final, and damaged, missing or incorrect shipments are "reviewed case by case" with no reship, replacement or refund stated for them, so no put-right remedy is stated (rule B1: 0, as for other vendors with the same wording).

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.
See the full score history and chart
- Most recent audit · 6.67to6.32
Shipping and transparency re-checked on 2 November 2026 after an independent re-audit. All sales are final and damaged or wrong items are reviewed case by case with no stated reship, replacement or refund, and the shipping policy gives a processing time of 1 to 3 business days, so both items score lower. A phone number is now shown on the contact page. Shipping 6.5 to 4.5, transparency 5.0 to 6.0.
- Audit · 7.33to6.67
Lab score recalculated on 24 October 2026 under rule A6 (certificate age): seven of the vendor's certificates, tested on 23 October 2025, became older than 12 months on 24 October 2026, and each certificate older than 12 months counts for a quarter less. Lab 7.7 to 6.5.
- Audit · 7.00to7.33
Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 7.1 to 7.7.

Claim deductions re-checked on 22 October 2026 under the published rule that a claim deduction applies only where a site claim is contradicted by what its certificates show, never for products merely lacking a certificate. Lab 7.0 to 7.1.
- Audit · 6.43to6.94
Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 6.0 to 6.5, pricing 6.0 to 9.5, operating history 4.0 to 2.2, transparency 5.5 to 5.0.

PSR withdrew its most serious finding after the owner disputed it and turned out to be right. We had reported that Quantum-332 Elite contained about 2 micrograms of SLU-PP-332. The laboratory's own record reads 2.021mg and 1.985mg; the copy published on the vendor's site carries a microgram unit in error. Injection pens and cartridges were also verified removed from the catalogue in the same period.

Editor’s notes
Hacker Peptides tests through two named laboratories and publishes certificates organised by batch, with a photograph of a branded vial on each so a reader can tie the document to the product in hand. Rather than trusting the posted copies, we read all 25 certificates in the vendor's library across Freedom Diagnostics and Chromate, including some for products we do not list, and on 19 October 2026 confirmed the search codes for 11 of the 14 currently listed products directly at Freedom Diagnostics' own file host, with matching results. Certificates are issued to Hacker Peptides rather than to a supplier, so they document this vendor's own lots. Reported net content runs over label on the examples we checked. Against that, the testing is old. The newest certificate dates from January 2026, and no endotoxin, sterility or heavy-metals result appears on any of them. Pricing is far below the market, at roughly 40 percent of the median per milligram across the 13 products we compared on 22 October 2026, and our own published guidance treats pricing dramatically below market as a warning sign. Here it sits on verified certificates with over-label content, which is the opposite of the usual pattern, so we report it rather than assume the worst. Our rubric makes no deduction for how prices are presented. On the product pages we checked on 6 October 2026, products showed a struck-through regular price beside a lower selling price. During our review we did not see any product offered at the struck-through price, so we compare the lower price, which is what a buyer pays. Two further things readers should know. Products spell GLP with a numeral one, as G1P-2 TZ and G1P-3 RT, which the owner describes as risk management in a hostile regulatory climate rather than concealment. On 22 October 2026, the product pages did not name the compounds, listing only codes such as G1P-2 TZ, while the certificates named the actual compound, which obscures a search rather than the contents, and we weight it accordingly. And the catalogue mixes research vials with capsules, tablets and a cosmetic powder, which sits awkwardly against research-use-only framing; injection pens and 3ml cartridges were removed during our review. Certificates cover 11 of the 14 products we list, all from Freedom Diagnostics and each confirmed at the laboratory on 19 October 2026; cagrilintide, glutathione and bacteriostatic water had none.
