Royal Peptides is an established store with independent test data, but strict payment and return terms. As of October 19, 2026 it has 34 tests listed on Finnrick, names Janoshik as a lab and mentions endotoxin testing. It accepts only Cash App and crypto, and all sales are final. We could read prices for only a few of its 60 products.
Notice: Royal 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 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.

Prices as listed on October 19, 2026, many shown as sale prices. Semaglutide 5mg was $36 and the 15mg size was out of stock. Epitalon 50mg was listed at $580, which looks out of line with the 10mg price; confirm it before ordering. We could not record prices for retatrutide, tirzepatide, BPC-157 or TB-500 in our check. See semaglutide prices, KLOW prices and epitalon prices, or the full price index.
Testing and COAs
Royal Peptides publishes a COA page, names Janoshik and mentions endotoxin testing. The labs are named by the vendor; we have not verified them. We did not see lot or batch numbers next to the certificates, which makes it harder to match a report to the vial you receive.
The stronger signal is outside data. Finnrick lists 34 independent tests for this vendor, the most recent from August 25, 2026. Check the results for your compound there.
What we like
- 34 independent tests listed on Finnrick.
- A named lab (Janoshik) and endotoxin testing mentioned.
- A broad catalog of 60 products.
- Low per-mg prices on semaglutide, KLOW and 5-Amino-1MQ.
What to watch
- Payment by Cash App and crypto only.
- All sales final unless stated otherwise in writing.
- No company name or address published.
- No lot numbers seen next to COAs.
- Epitalon 50mg listed at $580.
How it compares
Royal Peptides has more independent test data than many vendors, but fewer buyer protections. Compare it with all vendors we track, peptide deals this week and our ranked list.
Bottom line
Royal Peptides backs its claims with a named lab and a solid Finnrick record. Cash App and crypto payments with no returns leave little recourse if an order goes wrong. Check Finnrick and the COA for your compound first.
