Tydes looks like an operating, reasonably transparent research peptide vendor with a large independent test record. As of October 19, 2026, it publishes lot-matched COAs, mentions endotoxin testing, and has 44 independent tests listed on Finnrick. It does not publish a business address, testing lab names or payment methods, and its catalog sits behind an age gate.
Notice: Tydes'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.

Testing and COAs
Tydes runs a lab results page. The site shows lot or batch numbers next to its COAs, so a certificate can be tied to a specific production run. It also mentions endotoxin or sterility testing, which many vendors skip.
What's missing: the site doesn't name the labs that produced the certificates, so we couldn't say who ran them. On the independent side, Finnrick lists 44 tests for Tydes, the latest on September 16, 2026. That is a large number for this market. We don't have Finnrick ratings to report here, so check the results on Finnrick for the compound you care about.
What we like
- 44 independent tests on Finnrick, with a recent one in September 2026.
- Lot-matched COAs on a dedicated page.
- Endotoxin or sterility testing mentioned on the site.
- Prices below the index median on tirzepatide, semaglutide, TB-500, MOTS-c and tesamorelin.
- A clear shipping policy: US orders ship within one business day of payment.
What to watch
- No business address published.
- Testing labs are not named on the site.
- Payment methods are not listed publicly.
- US only. The site says it does not ship internationally.
- Retatrutide, BPC-157 and NAD+ were slightly above the index median.
How it compares
Tydes has more Finnrick tests than most vendors we track, and its pricing is competitive on the GLP-class compounds. See all vendors we track, peptide deals this week and our ranked list to compare.
Bottom line
Tydes is a live US vendor with lot-matched COAs, endotoxin testing and a deep independent test record. The gaps are on the disclosure side: no address, no named labs and no published payment methods. Check its Finnrick history for your compound before ordering.
