Is GenX Bio legit?
GenX Bio scores 4.39 out of 10 (Weak, #77 of 100) as of November 2, 2026 and does not meet our testing gate: 14 of the 37 products we score carry a certificate, 7 confirmed with the issuing lab (a lab we grade A); 1 of those certificates is vendor-issued or from a source whose independence we could not establish. Its strongest area is operating history (8.0/10), with over nine years of records; its weakest is lab testing (2.9/10).
On lab evidence, the heaviest-weighted factor, GenX Bio has no third-party testing we could independently verify, with COA work on record from Freedom Diagnostics Testing, MZ Biolabs. The testing gate applies because that testing could not be independently verified (Third-party testing not established); its limit for GenX Bio is 7.50, and this score is already below it. Its lowest price per milligram in our data is on MK-677 (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 credibility2.9/10
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: 7 of 37 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is fewer than half, so the testing cap applies (see the methodology).

Pricing7.8/10
We compared GenX Bio’s current single-vial prices on 35 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 11% below the market median (ratio 0.89), which the published scale maps to 7.8/10. checked
Operating history8.0/10
Counted from October 16, 2017, the earliest dated evidence of this business operating: 9.0 years as of October 22, 2026, which the published table maps to 8.0/10.
Domain genx.bio registered 2017-10-16 and never shown parked, for sale or used by another business (the Wayback Machine has no captures of it), so under the one domain rule it counts, as it does for every other vendor. It was earlier refused for lack of selling evidence, which the rule does not require. Sterling Path LLC appears only as "Powered by" in the footer, so it is not the operating company; the site names no seller entity.

- Lab re-checked on 2 November 2026 (issue #25): a Freedom Diagnostics certificate for retatrutide (GP-3 RT, three sizes, a lot per size) was confirmed at the laboratory. Reports for GP-2 TRZ (tirzepatide), a KLOW blend, NAD+ and SS-31 were also confirmed at the laboratory but are not counted, because the catalog sits behind a login and whether those products are offered for sale could not be read.
- Catalogue re-checked on 2 November 2026 from the signed-in catalogue, read in the owner's browser: GP-2 TRZ (tirzepatide, 10, 20 and 30 mg), the Klow Blend (80 mg per vial), NAD+ 1000 mg and SS-31 50 mg are on sale and in stock at regular price, so they are now carried and priced, and their Freedom Diagnostics certificates, re-confirmed at the laboratory, now count: 14 of 37 products have a certificate, 7 of them confirmed at the laboratory. Lab 2.0 to 2.9; the third-party testing cap still applies.

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 · 3.90to4.39
Catalogue re-checked on 2 November 2026 from the signed-in catalogue, read in the owner's browser: tirzepatide (GP-2 TRZ), a KLOW blend, NAD+ and SS-31 are on sale and in stock, so their Freedom Diagnostics certificates, confirmed at the laboratory, now count. Certificates cover 14 of the 37 products we list. The third-party testing cap still applies. Lab 2.0 to 2.9.
- Audit · 3.68to3.90
Lab evidence re-checked on 2 November 2026 after the company published new reports. A Freedom Diagnostics certificate for retatrutide (GP-3 RT), with separate lots for each size, was confirmed at the laboratory, so certificates now cover 10 of the 33 products we list. Reports for tirzepatide, a KLOW blend, NAD+ and SS-31 were also confirmed at the laboratory but are not counted yet, because the catalog sits behind a login and we could not confirm those products are offered for sale. The third-party testing cap still applies. Lab 1.6 to 2.0.
- Audit · 3.66to3.68
Pricing recomputed on 26 October 2026: a vendor was removed from the directory, which moved the market median for the same products: pricing 7.7 to 7.8.
Earlier audits (9)
- Audit · 3.33to3.66
Certificate library re-checked on 23 October 2026: two new certificates confirmed at the issuing laboratories. Lab 1.0 to 1.6.
- Audit · 3.35to3.33
Prices re-checked on 23 October 2026 under rule E (standing prices only): prices taken from a time-limited sale were replaced with the vendor's standing price, current prices were re-read, and other vendors' price changes moved the market medians pricing 7.8 to 7.7.
- Audit · 3.18to3.35
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 0.7 to 1.0. Note added 22 October 2026: a score on this entry was corrected from 3.34 to 3.35; it had been rounded down instead of half up.
- Audit · 3.11to3.18
Operating history re-checked on 22 October 2026 under the published rule (earliest dated evidence of the business, including a never-parked store domain and the named operating company, looked up for every vendor): operating history 6.6 to 8.0.
- Audit · 3.21to3.11
Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: transparency 6.5 to 4.5.
- Audit · 3.27to3.21
Re-scored on 22 October 2026 under version 2 of our published rules. The BPC-157 document names no laboratory and now scores the flat 2.0 that applies to every certificate whose source cannot be established. The testing gate is now computed from the certificates, and none of 33 products has a certificate confirmed at a directory laboratory. Lab 0.8 to 0.7. Score 3.27 to 3.21.
- Audit · 4.57to3.27
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 9.5 to 5.0, pricing 10.0 to 7.8, operating history 10.0 to 6.6, transparency 4.6 to 6.5.
- Audit · 6.19to4.57
Lab 3.75 to 0.8. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: certificates were found for 7 of the 34 products we list, none carries a key we could check, and all are more than 12 months old. One of the seven, for BPC-157, names no laboratory.
- Audit · Verified, no change
Re-audited from live COAs. Refreshed 7 MZ Biolabs reports; one anonymous BPC-157 COA with no named lab remains a concern, and sparse COA coverage keeps the lab rating low.
Editor’s notes
GenX Bio (genx.bio) publishes certificates for a small part of its catalog. Six are MZ Biolabs reports (Tucson, Arizona) for semaglutide, CJC-1295 without DAC, MT-2, HCG, GHK-Cu and TB-500, dated July 2023 to July 2024, with purities of 98.9% to 100%. They cover HPLC purity and MS identity only, with no endotoxin or sterility, and carry no key we could check. MZ Biolabs does not publish ISO/IEC 17025 accreditation. The BPC-157 document names no laboratory. Most of the 37 products we list have no certificate on file, and the MZ Biolabs certificates are more than a year old, which is why the lab score is low. The catalog sits behind a researcher login. On 22 October 2026 the site said orders ship within one to two business days, with free FedEx 2Day shipping on domestic orders above an order minimum, and product pages listed payment by major credit and debit cards. On 22 October 2026 the site's footer named Sterling Path LLC, and the site gave a contact email, a Houston, Texas street address and a phone number, but named no owners. The genx.bio domain was registered in October 2017, and although the earliest dated evidence found of GenX Bio selling is from August 2020, the operating-history score as of 22 October 2026 reflects the October 2017 domain registration date. Retatrutide is sold as GP-3 RT and tirzepatide as GP-2 TRZ. Certificates cover 14 of the 37 products we list: six MZ Biolabs reports from July 2023 to July 2024 that carry no key we could check, one, for BPC-157, that names no laboratory, and seven Freedom Diagnostics reports from October and November 2026, for tesamorelin, the BPC-157/TB-500 blend, retatrutide, tirzepatide, a KLOW blend, NAD+ and SS-31, which name GenX Peptides as the client and which we confirmed at the laboratory on 23 October and 2 November 2026. On 2 November 2026 the signed-in catalogue, read in the owner's browser, showed tirzepatide, the KLOW blend, NAD+ and SS-31 on sale and in stock, so they are now counted.

GenX Bio: Frequently Asked Questions
Is GenX Bio legit?
GenX Bio scores 4.39 out of 10 (Weak, #77 of 100) as of November 2, 2026 and does not meet our testing gate: 14 of the 37 products we score carry a certificate, 7 confirmed with the issuing lab (a lab we grade A); 1 of those certificates is vendor-issued or from a source whose independence we could not establish. Its strongest area is operating history (8.0/10), with over nine years of records; its weakest is lab testing (2.9/10).
Is there a GenX Bio promo code, coupon code, or discount code?
We do not have a verified GenX Bio promo code or coupon code right now. When GenX Bio runs a sale or issues a discount code, we post it here and on our promos page, so bookmark this page for the latest GenX Bio discount.
Does GenX Bio use third-party lab testing?
Not to our verification standard. Fewer than half of this vendor's scored products have a certificate from an independent laboratory in our directory (not tier D) whose verification key we confirmed at that laboratory, so the testing gate applies. This records what we could verify; it is not a finding of a quality or safety problem. Laboratories on the certificates we hold: Freedom Diagnostics Testing, MZ Biolabs.
Where can I see GenX Bio's COAs?
In the "GenX Bio COAs and lab test results" table on this page. We hold 14 certificates for GenX Bio, covering 14 of the 37 products we track, issued by 2 laboratories (Freedom Diagnostics Testing, MZ Biolabs). 7 products' certificates were confirmed at the issuing laboratory itself. Each row links the certificate, its lab, its test date and the purity it reports.
What peptides does GenX Bio carry?
GenX Bio carries BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, Semax, Selank, Melanotan-2, and 29 more. Current per-milligram pricing, COA links, and verification keys for each are in the comparison table on this page.
