We've been offering real pharma quality IGF1, and encourage the members to test, whether by Jano or any other independent lab
It's highly important as the IGF1-lr3 (unlike GH for instance) can't be tested in blood tests, so full HPLC is the only accurate indication. The IGF1-lr3 is simply a different molecule then the endogenous IGF1 our body secrets, so it can't be tested by the regular serum (ELISA) kits.
