Skye Peptides has strong outside test coverage but publishes very little about itself. Finnrick lists 93 independent tests for the vendor, the latest dated September 29, 2026. On its own site we found no COA page, no named lab, no address and no company name. Prices are mixed: large sizes are often below the median across the vendors in our price index, small sizes often above it.
Notice: Skye Peptides' 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. 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
We found no COA page on skyepeptides.com and no testing lab named anywhere on the pages we could reach. The site also doesn't mention lot or batch numbers next to certificates, or endotoxin or sterility testing.
The independent picture is better. Finnrick lists 93 tests for Skye Peptides, with the most recent on September 29, 2026. That is a large number of customer-submitted samples. We don't report Finnrick ratings here, so check the vendor's page on Finnrick for results by compound.
What we like
- 93 independent tests on Finnrick, recent as of late September 2026.
- A broad catalog of 44 peptide products.
- Large sizes are often well below the index median, for example MOTS-c 50mg (52% below) and tesamorelin 24mg (47% below).
- Prices are visible for most products we checked.
What to watch
- No COA page and no named testing lab on its site.
- No address, company name or owner published.
- Payment methods aren't listed on public pages.
- Small sizes can be expensive per mg, such as tirzepatide 10mg (65% above the median) and selank (58% above).
- GLP-class products are sold under codes (GLP-1 R, GLP-1 T, GLP-1 S).
How it compares
Skye Peptides has more independent test data than most vendors we track, but less on-site disclosure than vendors that publish named-lab COAs. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Skye Peptides is a live store with a large catalog and a long Finnrick test record. Its own site gives you little to verify: no COAs, no lab names and no address. If you buy for research, favor the larger sizes on price and check Finnrick for the specific compound first.
