Built for serious science.
We exist to give researchers access to the highest-quality, most rigorously tested research peptides available — every batch, every time.
Who We Are
Trustworthy supply in an untrustworthy market
The peptide research space is crowded — but verified, transparent, USA-compounded sources are rare. That gap is exactly why Peptiva Research Labs exists.
We're a Miami-based supplier dedicated to one thing: giving researchers access to high-purity peptides they can actually trust. Every compound we offer is USA-compounded, third-party tested, and backed by a downloadable COA for every batch. No guessing. No ambiguity. Just clean science.
What sets us apart
What we don't do.
We don't source from China.
Every compound is USA-compounded at a licensed domestic facility.
We don't ship without a COA.
If the batch hasn't been independently verified, it doesn't leave our facility.
We don't sell anything we haven't verified.
Every product on this site has passed HPLC and mass spectrometry testing.
