IGF-1 LR

IGF-1 LR3 is insulin-like growth factor 1 with a 13-residue extension that keeps it away from binding proteins, which is what gives it its long active window in cell culture. It is a workhorse of proliferation and muscle-tissue research. Supplied lyophilized in a 1 mg vial and shipped with a cold pack at no extra charge; every lot carries its own certificate.

Sold strictly as a reference material for laboratory research. We do not provide dosing information or administration instructions.

Every lot is tested by an independent laboratory using HPLC and mass spectrometry. The lot in stock right now is BV-2408-IGF01.

The certificate reports four things: identity, purity, water content and the absence of residual solvents. If any of the four is missing, the document is incomplete.

We send it in the WhatsApp thread before you pay, and it is worth knowing how to read it: how to read a COA.

The vial arrives sealed and lyophilized. Refrigerate it on arrival; for long holds, keep it frozen and away from light.

This compound ships with a cold pack at no extra charge, and the box is packed so it arrives cold.

Handle it under laboratory conditions only. We do not supply reconstitution instructions, dosing information or injection supplies of any kind.

Confirmed before 2pm ET on a business day, it leaves the same day. Two to four business days across the continental US, with tracking. Flat $12, free over $200, in a plain box with nothing printed about the contents.

Unopened vials can be returned within 14 days of delivery. The full terms are here: shipping policy.
