Born From Frustration.
Built for Precision.

While searching for high-quality research peptides, we kept running into the same problems: inconsistent quality, vague sourcing, and a lack of transparency. It always felt like a gamble. Were these peptides made in the U.S.? Were they tested? Were they even what they claimed to be?

So we decided to fix the problem ourselves. Proliven Labs was created to raise the standard for research-grade peptides, offering the clarity and confidence researchers need. We believe in sourcing high-quality, small-batch compounds, fully tested and verified for purity by third-party labs.

At Proliven Labs, we strive to set the standard for the peptide industry. We are committed to:

Reliability: We source every peptide in small batches from US suppliers, ensuring tight quality control and consistency.

Purity: Our peptides are tested for 99%+ purity and verified by third-party labs.

Integrity: We believe in full transparency. Certificates of Analysis (COA) are available for every batch we supply.

What sets us apart? At Proliven Labs, we don’t just resell peptides — we craft solutions. We ensure that each product is sourced from USA suppliers, 3rd-party tested by strict laboratories, and conforms to the highest industry standards. Our customers trust us for:

Third-Party Testing: COA verification ensures that you’re getting exactly what you need.

Small-Batch Consistency: All peptides are 3rd-party test in small batches. We personally send each peptide to the laboratory, unlike mass-produced competitors.

Transparency: Full access to test results and batch codes.
