What we hold

These are the current laboratory certificates for our range. They cover 26 of the 47 compounds we sell in a vial. Where a compound is not on this page, we hold no certificate for it and make no claim about it.

Two of them — Follistatin and Kotho — are sold in our supplier’s own labelling, so the certificate covers the batch in the box. The rest test raw material rather than a finished vial, and none of them is issued to Optimal Lab. Most were issued to our raw-material supplier; the remainder name a different client, or name no manufacturer at all. Those certificates report two things: how much compound was measured, and its purity by HPLC. They do not test identity, and we do not claim it.

Every report below opens in full. Nothing on this page is summarised from memory — if a certificate does not state something, this page does not state it either.

Check your vial

Pick the compound and when you bought it, or look it up by order number, and this will tell you which of the certificates below covers it.

Choose the research compound and enter the purchase date from your order confirmation. We will show a report only where a batch-matched record is explicitly on file.

Use the date shown on your order confirmation.
