Every compound we supply is independently verified before it reaches a researcher's hands. Our quality framework is built on third-party testing, documented traceability, and a zero-tolerance policy for unverified compounds, because research integrity begins with supply integrity.
Our quality process does not begin at the point of sale. It begins at the point of sourcing, before a compound is accepted into our inventory. The following steps apply to every compound in our catalog, without exception, from short peptides like BPC-157 to complex acylated compounds in our GLP-1 research category. All compounds are verified and shipped from our Houston, TX facility.
Candidate compounds are evaluated for synthesis origin and manufacturer documentation. We do not accept compounds from sources that cannot provide synthesis records and pre-shipment quality data. This is the entry gate, not the exit gate.
Upon receipt, compounds are submitted to an independent, accredited analytical laboratory for verification. We do not use the manufacturer's own test data as the basis for product qualification. Independence in testing is non-negotiable.
High-performance liquid chromatography (HPLC) is used to determine purity percentage. The ≥99% threshold must be confirmed by this analysis. Results below this threshold result in rejection of the entire batch, no partial acceptance.
Mass spectrometry (LC-MS or ESI-MS) is used to confirm the molecular identity of the compound against the expected molecular weight and fragmentation pattern. Purity alone is insufficient, identity must also be confirmed.
Upon successful verification, a Certificate of Analysis is generated referencing the specific batch, test dates, laboratory, purity result, and identity confirmation. This COA is permanently associated with that batch and made available with every order from that batch.
Verified compounds are stored under appropriate conditions for lyophilized peptides. Cold-chain packaging is used for shipment to maintain compound stability. Batch traceability is preserved through fulfillment.
A Certificate of Analysis is only as useful as the information it contains. Our COAs include the following data points for every compound and batch:
Compound name and CAS number. Batch or lot number. Date of manufacture and date of testing. Testing laboratory name and accreditation. HPLC purity result with chromatogram. Mass spectrometry molecular weight confirmation. Appearance description. Residual solvent analysis (where applicable). Storage recommendations. Retest date.
COAs are available for download at the time of order and are permanently archived for records purposes.
Transparency requires stating not only what we do, but what we categorically do not do. These are firm operating principles, not aspirational guidelines.
We do not accept compounds without independent third-party verification. We do not use supplier-provided COAs as the sole basis for product qualification. We do not ship batches that fail purity thresholds. We do not list compounds we cannot fully document. We do not make medical claims about research compounds. We do not sell to anyone representing intent to use compounds for human consumption.
FOR RESEARCH USE ONLY, All compounds supplied by Lone Star Peptide Co. are intended exclusively for laboratory and in vitro research applications. Quality documentation is provided to support legitimate research procurement. These compounds are not approved by the FDA for human consumption, therapeutic use, or clinical application. Purchasers are responsible for all applicable regulatory compliance.
