Verified twice
The peptide market's central problem is that most product is sold on a supplier's word alone — underdosed, mislabelled, or untested. Our answer is verification you can check yourself: every batch is tested independently by a third-party laboratory and again by us, and the third-party certificate ships with the pen.
how every batch is verified
1. Independent third-party assay (Asterion Analytics). Each batch is tested by an independent laboratory, which issues a batch-specific certificate of analysis (COA). The COA reports the compound's identity, its HPLC purity and peptide content, and a panel of safety checks — and it's tied to the exact lot number on your pen, so it describes your product, not a generic sample.
2. Our own internal testing. Before a batch is released we verify it again with our own in-house testing, so the third-party result isn't the only check standing between the batch and you. That second, independent pass is what "verified twice" means.
what the certificate reports
Each Asterion COA is a one-page document covering:
- Identity — sample and product name, chemical name, CAS number, molecular formula and mass, confirmed by LC-MS.
- Batch — lot number, manufacturing date and retest/expiry date.
- Purity & content — HPLC purity and peptide content, with an annotated chromatogram.
- Safety panel — water content (Karl Fischer), heavy metals (ICP-MS) and endotoxin (LAL test).
- Handling — appearance and storage conditions (cold, protected from light).
Two guides walk through it in detail: how to read a COA and what HPLC purity does and doesn't prove.
checking your own batch
Every pen carries a lot number. Match that number to the COA supplied with your order to confirm the certificate describes the batch in your hand — the single most useful check a buyer can make in this market. The step-by-step is in verify your batch.
