The Founder

Founded in Houston
With a Mission

The founder spent over a decade building companies in Houston’s demanding construction and energy markets, where one principle became non-negotiable: if you can’t verify it, you can’t trust it. That standard came from industries where real results and long-term performance are the only measure that matters.

When that same scrutiny was applied to the peptide supply market, the gap was clear. Suppliers making purity claims with no documentation. COAs with no traceability. Researchers left to guess what was in the vial. Lone Star Peptide Co. was built to close that gap.

Every vial ships with a batch-specific Certificate of Analysis, independently verified by a third-party accredited laboratory.

Every batch is fully traceable and searchable in our public COA library by batch ID.

No medical claims, no dosing advice, research-only, always.

Our Mission

Why Lone Star
Exists

For serious research, transparency is non-negotiable.

Researchers are tired of guessing what is in the vial. We built Lone Star Peptide Co. to fix that, supplying research-grade peptides with complete documentation, verifiable purity, and a commitment to the integrity of your work. When Peptide Sciences shut down in March 2026, thousands of researchers needed a verified, domestic alternative. Lone Star carries the same compounds — triple-tested, Houston-based, same-day shipping.

COA Library

Every batch’s Certificate of Analysis is publicly searchable. Full HPLC, Mass Spec, and Endotoxin data, one click away.

Batch Traceability

Every vial is labeled with a unique batch ID that links directly to its COA. Unbroken chain of custody from synthesis to your lab.

Third-Party Testing

Independent, accredited labs verify every batch. Not the manufacturer. Not us alone. Three labs. Because your research depends on it.
