Recorded from MY PEPTIDES’s own public website on 29 Jul 2026. “Not stated” means we did not find the information on their site, not that it is absent from their business.

- Per-product COA pages are browsable without ordering, and the library also lists compounds whose COA has not yet been uploaded.
- Products ship as pre-mixed solutions rather than lyophilised powder, so no reconstitution step or bacteriostatic water is required.
- No company registration number is published on the site.
MY PEPTIDES sells single research compounds and pre-combined multi-peptide sets, dispatched from the UK.
The distinguishing attribute against most of this list is that Certificates of Analysis are publicly browsable before ordering, at a per-product URL, rather than only shipping with an order. That lets a buyer check the testing format and the recorded purity figure while still deciding. The library also lists compounds whose COA has not yet been uploaded, which is visible rather than hidden.
The second distinguishing attribute is format: products ship as pre-mixed solutions rather than lyophilised powder. That removes the reconstitution step and the need to source bacteriostatic water, at the cost of requiring refrigeration on arrival and ruling out long-term frozen storage. Whether that trade is worth making depends entirely on the use case — see pre-mixed vs lyophilised peptides.
