Core Molecular Specs & Technical Index
Peptide Sciences specializes in research-grade peptides with a guaranteed purity of ≥99% by HPLC. Their product line includes GHRP-2, BPC-157, and TB-500, each supplied as a lyophilized powder. Solubility varies by peptide: most are soluble in sterile water or bacteriostatic water, with storage recommended at -20°C for long-term stability. Key technical parameters include molecular weight verification via mass spectrometry, sequence confirmation, and endotoxin levels below 1 EU/mg. The brand emphasizes batch-specific COAs with detailed chromatograms.
- Purity: ≥99% verified by HPLC and MS for every batch.
- Solubility: Optimized for sterile water; some require acetic acid for full dissolution.
- Stability: Lyophilized form stable for 24 months at -20°C.
- Endotoxin: <1 EU/mg, meeting research-grade standards.
- Verification: Third-party HPLC/MS reports available per lot.
Industry data shows that peptides with ≥99% purity reduce aggregation risks by 40% compared to 95% purity grades, critical for reproducible research outcomes.

Bulk Purchase Selection Guide
When buying peptides in bulk, common pitfalls include accepting incomplete COAs, ignoring storage conditions, and choosing unverified suppliers. Selection standards require batch-specific HPLC/MS reports, GMP certification, and clear labeling of molecular weight. A buyer checklist should include verification of third-party testing, review of purity levels, and confirmation of endotoxin limits. Peptide Sciences meets all these criteria, though pricing is higher than generic alternatives.
- Pitfall 1: Relying on supplier-provided COAs without third-party confirmation.
- Pitfall 2: Ignoring storage requirements leading to degradation.
- Standard 1: Demand batch-specific HPLC chromatograms.
- Standard 2: Verify GMP certification documents.
- Checklist: Confirm purity ≥99%, endotoxin <1 EU/mg, and MS data.
