Trust Index breakdown

DerivedV3

The Trust Index weighs five evidence pillars — purity claims-vs-reality, testing transparency, enforcement conduct, operational accountability and reputation integrity — into a single 0–100 factor. Nothing here can be bought.

Thinly Documented. Cited facts on file, but no allowlisted independent assay yet — a precise index is withheld. A precise number is withheld rather than guessed — absence of evidence is never shown as a low score.

WHOIS: GenX's About page and Crunchbase both state a 2013 founding ('Founded in 2013'). However, the genx.bio domain is registered through EuroDNS with a domain age of ~8–8.5 years as of mid-2026 — i.e. created ~2017–2018, roughly 4–5 years AFTER the claimed founding. No earlier GenX-branded domain was located to reconcile the gap. Surfaced as an identity/age discrepancy for review; the exact creation date could not be pulled from who.is/whois.com in this environment. who.is

not on record

GenX's About page states all peptides are tested by 'high-performance liquid chromatography-mass spectrometry (HPLC/MS)' and describes the company as an 'accredited quality assurance provider', but does NOT name the testing laboratory and does not host a public per-compound COA repository or batch-verify tool that the crawl could locate. A third-party review (Peptide Protocol Wiki) attributes the testing to 'MZ Biolabs' and reports products are 'TFA-free' and that 'batch-specific COA availability may vary' — these lab/process details are review-attributed and were NOT confirmed on GenX's own pages. No independent third-party purity assays (Finnrick/Janoshik/vialaudit) for GenX were found.

FAQ

CitedV31

Is GenX Peptides legit, and what is on record?

GenX Peptides (genx.bio) is a US-facing, Houston, Texas budget research-peptide retailer that claims operation since 2013 and 'made in America' production with HPLC/MS testing. On record: a small but mostly positive review footprint (Trustpilot ~4.3/5 over 16 reviews; Reviews.io ~4.0/5 over 4; Knoji ~3.7/5 over ~60), lenient algorithmic 'safe' verdicts (ScamAdviser, Gridinsoft 80/100), and mid-tier editorial coverage (Muscle & Brawn 4/5; outliyr 3.8/5). Caveats: the review samples are very small and one Reviews.io user disputes the platform's authenticity and the company's address, the testing lab is not named on GenX's own pages, and the domain (registered ~2017–2018) is younger than the claimed 2013 founding. No FDA warning letter or verified BBB profile was located. PeptideCompass computes no vendor score — weigh the cited facts yourself. Research use only.

trustpilot.com

Where does GenX Peptides ship, and how fast?

GenX ships from the US via USPS Priority / UPS with delivery confirmation; orders process in 1–2 business days. US/Canada Priority is ~2–3 business days (Flat Rate 2–6); the shipping page states GenX ships worldwide, though one third-party review described it as US-only. Free shipping applies to domestic orders over $200 (a third-party review lists $150 — figures conflict). Research use only.

genx.bio

What payment methods does GenX Peptides accept?

GenX's site advertises Visa/Mastercard credit cards plus Bitcoin (crypto). One editorial review instead described payment as 'crypto and electronic check only' — so the exact mix should be confirmed at checkout. Limited payment flexibility is a recurring criticism across reviews.

genx.bio

Does GenX Peptides provide COAs or lab tests?

GenX's About page states peptides are tested by HPLC/MS and calls the company an 'accredited quality assurance provider,' but it does not name the testing laboratory and the crawl found no public per-compound COA repository or batch-verification tool. A third-party review attributes testing to 'MZ Biolabs' and reports products are TFA-free, but that is unconfirmed on GenX's own pages, and no independent third-party purity assay (e.g. Finnrick/Janoshik) for GenX was found. Research use only.

genx.bio

What is the return and refund policy?

GenX does not accept returns 'due to the delicate nature of peptides' unless there is a manufacturing defect or transit damage. Carrier-lost packages (tracking shows non-delivery) are reshipped free, but packages marked 'delivered' are not. International orders returned to GenX are refunded at 85% (15% restocking fee, minus shipping); seized international orders may be resent at a 50% discount with documentation. Research use only.
