GenX Bio has competitive GLP-class prices but publishes almost no company or testing information. As of October 19, 2026, genx.bio lists 27 peptides with public prices, including retatrutide and tirzepatide below our index median. We found no COA page, no company name, no address, no named labs and no Finnrick tests.
Notice: GenX Bio's products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices only. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

The GLP-class items are the value here; several small-vial items cost far more per mg than the median. Compare retatrutide prices, tirzepatide prices and semaglutide prices in our price index.
Testing and COAs
We didn't find a COA or lab results page on genx.bio. In fact, our check only found the homepage; we didn't locate shipping, returns, contact or about pages. The site doesn't name any testing labs, we saw no lot or batch numbers tied to certificates, and we found no mention of endotoxin or sterility testing.
We also found no Finnrick tests for GenX Bio. That leaves no public evidence, from the vendor or from independent testers, of what's in its vials.
What we like
- Retatrutide and tirzepatide priced 23-28% below our index median.
- NAD+ and selank also below the median.
- Prices are public, with no login or age gate.
- Multiple sizes on the GLP-class items (10mg to 30mg).
What to watch
- No COA page found.
- No company name, address or founding year published.
- No testing labs named and no Finnrick tests found.
- No shipping, returns or contact pages found in our check.
- Small vials of MOTS-c, ipamorelin and thymosin alpha-1 are priced far above the median per mg.
How it compares
GenX Bio competes on GLP-class pricing but lags most vendors we track on disclosure. Vendors with named labs and lot-matched COAs give you more to check. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
GenX Bio's retatrutide and tirzepatide prices are low, but the site offers almost nothing to verify: no COAs, no company details and no independent tests. Until that changes, treat it as unverified.
