Description
IGF-1 LR3 is a long-arginine-3 analogue of Insulin-like Growth Factor 1, modified to reduce binding to IGF-binding proteins so that a greater proportion remains bioactive in circulation. That modification is the whole point of the analogue: it lets researchers study IGF-1 receptor activation with less confounding from binding-protein sequestration than native IGF-1.
IGF-1 LR3 is a standard reference compound in muscle-growth and cellular-proliferation research precisely because of this extended bioavailability relative to the native hormone.
After you place your order, a licensed physician will speak with you directly on a live call to review your health history and confirm a prescription is medically appropriate before anything ships. If your order isn’t approved, our team will contact you directly instead of shipping it. Reconstitute with bacteriostatic water (with 0.1% acetic acid or per your lab’s standard IGF protocol) and store refrigerated.
