Three tests. Every batch.
Every lot is tested by an independent laboratory before it reaches our catalog. No exceptions.
HPLC for purity, an identity check against the declared compound, a quantity assay reporting the milligrams weighed out of the vial, and lot archival linking every batch to its certificate.
What gets checked.
Purity
HPLCHow much of the powder is the peptide you ordered. This is the percentage printed on the certificate.
Identity
Confirms the compound in the vial is the one on the label, not something close to it.
Quantity
How many milligrams the laboratory weighed out of the vial, against the size on the label.
We do not run any of these tests.
Glow does not manufacture and does not operate a laboratory. Testing is Accumark Labs, an independent lab with no stake in the result, and the certificate is issued in their name. Their ISO/IEC 17025 accreditation is pending, not granted, so read their reports as the work of an independent laboratory rather than an accredited one.
You do not have to take any of this from us. Every certificate carries the laboratory’s own report reference, and accumarklabs.com/verify checks it against their records. Each certificate on this site links it with the reference already filled in.

Research use only.
- Not for human or veterinary use, not for diagnostics, and not evaluated by the FDA.
- One lot, one certificate. Every result is issued against the lot number printed on your vial.
- We do not grade our own inventory. The laboratory that ran the analysis issues the document, not us.
- No lot is screened for heavy metals and no lot is given an appearance and solubility inspection. Sterility and endotoxin are run on some lots and not others, so read the certificate for the lot you have.
