Built around better research inputs
Small team.
Serious standard.
Simple Peptide is a family-run research materials company focused on disciplined U.S.-based production, clear lot documentation, and support that answers.
Why we started
Research purchasing should feel less opaque.
We began in late 2023 with a straightforward idea: qualified research customers should not have to choose between responsive service, fair pricing, and traceable product documentation.
As the company grew, we moved closer to production and built operating standards around incoming material review, controlled lyophilization, independent testing, and accessible lot records.
The operating standard
What quality means here.
- 01
Incoming material threshold
Our incoming API target is 99.7% purity before lyophilization. Finished-lot specifications are molecule-specific; our standard is 99% purity or better where the molecule supports it, with any applicable exception documented by the lot COA.
- 02
Independent verification
Third-party analytical review supports identity and purity decisions. The applicable lot Certificate of Analysis is the controlling record.
- 03
Expanded lot testing
COAs issued May 2026 and later include sterility, endotoxin, purity, and net peptide content testing.
- 04
Reachable support
Our U.S.-based team supports order, account, shipping, and documentation questions by phone and email.
Our commitment
Transparency is a practice, not a slogan.
We publish the boundaries of what we sell, keep lot documentation accessible, and avoid personal-use guidance. Every product is intended solely for qualified laboratory research—not for human or animal use.
