Is IGF1-LR3 third-party tested?

Yes. Every IGF1-LR3 lot runs a 7-point QC panel at an independent third-party US lab: identity, purity by HPLC, quantity, sterility, endotoxins by LAL, heavy metals by ICP-MS and a fentanyl screen. The signed certificate for the exact lot you receive is published before you order. The signed certificate of analysis for the exact lot you receive is published on the lab reports page and available before you order.

How do I verify my IGF1-LR3 is legit?

Match the lot number printed on your vial to the certificate of analysis published on the Next Level Labs lab reports page. It names the lab, batch, purity, and identity confirmation for that exact lot, so a real report always maps to your specific vial.

01 — Description

What it is

IGF1-LR3 is an analog of insulin-like growth factor 1 carrying an arginine substitution at position 3 and a 13-residue N-terminal extension. Those modifications reduce binding to IGF-binding proteins, which is why it is used in cell-culture signaling research.

Supplied as a lyophilized powder and sealed against light and moisture. Strictly for in vitro laboratory research.
