IGF-1 LR3

How much IGF-1 LR3 is in a Clean Peptide vial?

Short answer

Slightly more than the 1 mg label. ILS Laboratories measured 1.03 mg of net peptide in Clean Peptide's IGF-1 LR3 1 mg lot ACE-1279625 (103.0% of label), on certificate COA-2026-IIZXM6, analysed 9 September 2026. ILS's own portal shows the same figure. Net peptide content is separate from HPLC purity, which read 99.90%.

Measured content against the label

Read from the live lot pages on 30 October 2026. Share of label is the measured content divided by the labelled size. The figure is also checked against the certificate image and ILS's portal record.

At a 1 mg label the amounts are small: 1.03 mg is 0.03 mg above label. Net peptide content is the milligrams of IGF-1 LR3 the laboratory measured in the vial it tested; HPLC purity is a different figure, the IGF-1 LR3 peak as a share of the peptide-related peaks, so the certificate reports both.

ILS lists the content figure as "Report Only", with status N/A: a measured value with no pass or fail limit, so the certificate states the amount rather than a tolerance around the label. The notes on the certificate describe the methods for purity, identity, heavy metals and endotoxin, but not for net peptide content.

Follow-up questions

Who issued the certificate, and can I check it?

ILS Laboratories, certificate COA-2026-IIZXM6. The link below opens the same certificate on ILS's portal, which lists net peptide content as 1.03 mg.
