Do Clean Peptide vials contain the labelled amount?

Short answer

Yes, on every freeze-dried size with a measured-content result in October 2026. The lot pages range from 103.0% of label (IGF-1 LR3 1 mg, 1.03 mg) to 107.3% (GLP-3 Reta 30 mg, 32.2 mg), and the KPV 10 mg certificate reads 12.94 mg. Two sprays measured just under label but within specification.

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. Share of label is the measured content divided by the labelled size. KPV is read from the certificate image. CJC-1295 10 mg is covered on its own lot page.

The two sprays below label: Adamax Spray measured 0.98 mg/mL against a label of 20 mg in 20 mL (1 mg/mL), and Selank Spray 19.69 mg against 20 mg. Both pass their specification of not less than 90% of label claim.

Measured content is separate from HPLC purity. A vial can read high on one and low on the other, which is why both are on each certificate that reports content.
