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, lab tested in Texas, Houston-based, same-day shipping.

Public COAs

Every batch’s Certificate of Analysis is public on its batch page, with HPLC purity and mass spec identity, one click away.

Batch Traceability

Every vial carries a batch ID that matches its public batch page and COA, so you can check the exact lot you received.

Tested in Texas

Every lot is tested by labs in College Station, TX before it ships, not only by the manufacturer. The results are on the batch page.

GHK-Cu	100 mg	103.13 mg

Some lots come in under the target and some come in over. The batch page tells you which, so your numbers start from what is actually in the vial.

Measured milligrams, not the fill target

A vial is filled to a target weight, and the real amount drifts. Every Lone Star batch record lists what the lab measured next to that target. How we measure it
HPLC purity and mass spec identity

Each batch is checked for purity by HPLC and for identity by mass spectrometry. All five batches shown here read 99.9% purity on their records. How to read a COA
Ships from Houston the same day

Order by 3 PM CST on a business day and it normally ships that day, packed in an insulated box with gel ice packs. On high-volume days it can take one more business day. Shipping details
