Which Clean Peptide certificates do not report HPLC purity?
Short answer
Six of the 36 sizes in the certificate library in October 2026 have no HPLC purity figure: four nasal sprays from HYTE Research Division (Adamax, DSIP, PT-141 and Semax), whose certificates test identity and quantity only, and both bacteriostatic water sizes, whose Accurate Test Labs report covers endotoxin. The other 30 sizes all report a purity figure.
Sizes whose certificate has no HPLC purity result
| Product | Size | Laboratory | Tests on the certificate | What it reports instead |
|---|---|---|---|---|
| Adamax Spray | 20 mL | HYTE Research Division | Identity & Quantity | Identity confirmed (HPLC-DAD); concentration 0.98mg/mL (Curve Assay) |
| Bacteriostatic Water | 3 ml | Accurate Test Labs | Endotoxin only | Endotoxin 0.50 EU/ml against a limit of 350.00 |
| Bacteriostatic Water | 10 ml | Accurate Test Labs | Endotoxin only | Endotoxin 0.50 EU/ml against a limit of 350.00 |
| DSIP Spray | 20 mL | HYTE Research Division | Identity & Quantity | Identity confirmed (HPLC-DAD); concentration 1.18mg/mL (Curve Assay) |
| PT-141 Spray | 20 mL | HYTE Research Division | Identity & Quantity | Identity confirmed (HPLC-DAD); concentration 1.31mg/mL (Curve Assay) |
| Semax Spray | 20 mL | HYTE Research Division | Identity & Quantity | Identity confirmed (HPLC-DAD); concentration 1.15mg/mL (Curve Assay) |
KLOW 80 mg, also on sale, shows its HYTE Research Division certificate on its product page but has no lot page yet, so it is not counted here.
Read from the live lot pages on 30 October 2026. The bacteriostatic water 3 mL and 10 mL sizes share one certificate.
A certificate shows only the tests the client requested. The four spray certificates list "Identity & Quantity" as the tests requested; the bacteriostatic water report lists endotoxin alone. The fifth spray, Selank Spray, was tested for purity, identity and quantity and reads 99.74% by HPLC-DAD.
Of the 30 sizes with a purity figure, the 24 ILS Laboratories lots name HPLC; GLP-2 Tirz 20 mg, KPV and Selank Spray name HPLC-DAD. The lot pages for BPC-157 20 mg, GLP-2 Tirz 30 mg and Epithalon give the figure without naming a method.
Where to verify
Follow-up questions
Does no purity figure mean the spray failed a purity test?
No. Purity was not one of the tests requested on those four certificates, so there is no result either way. Each passed the tests it did list: identity, and a concentration of not less than 90% of the label claim.
