How we test every single batch (and why we brag about it)

No batch leaves without a passing COA

Every lot we receive goes into quarantine the moment it lands. Nothing is sellable until it clears third-party HPLC-MS purity testing.

The pipeline

1. **Receiving** — lot logged, quantity verified, quarantined.
2. **Sampling** — a representative sample is pulled and sent to an independent lab.
3. **Testing** — purity by HPLC-MS. We hold a hard 99% threshold on peptides.
4. **Release** — only a passing certificate of analysis clears a lot to sell.

When a lot fails, it's destroyed — not quietly re-graded. That's the whole point. We don't ship mid.
