Pepcore Labs exists because the research peptide market is opaque. Most suppliers won't tell you where their material is synthesized, who tested it, or what "≥98% pure" actually means in their assay. We took a different approach.

Manufacturing

Every peptide we sell is synthesized in cGMP-aligned facilities using solid-phase peptide synthesis (SPPS). Material is lyophilized under controlled vacuum, vialed under nitrogen, and stoppered before shipment to our cold-storage partner.

Testing

Every lot is independently assayed by ISO 17025-accredited laboratories before release. Standard panel: HPLC purity, ESI-MS molecular weight confirmation, endotoxin (LAL), residual solvents, and water content. Lot-specific COAs are published to our COA library and printed via QR on every vial.

Fulfillment

Orders ship from US facilities via tracked, temperature-controlled carriers within 1–2 business days. We use ice packs and insulated packaging where the compound requires it.

What we don't do

We don't market our products for human use. We don't recommend dosages. We don't host customer testimonials about personal use. If you're looking for that kind of supplier, you'll be happier somewhere else — and we'll both be safer.
