IGF-1 LR3 1mg

IGF-1 LR3 is a synthetic analogue of human insulin-like growth factor 1 (IGF-1). It has 83 amino acids: the 70 of IGF-1, with arginine in place of glutamic acid at position 3 (the R3 of the name) and a 13-amino-acid extension at the N-terminus (the L, for long). Our IGF-1 LR3 comes as 1mg of lyophilised (freeze-dried) powder at 99% purity, with the strength printed on the pack. Store the powder at 2–8°C, sealed and away from light.

For how lyophilised peptides are stored, read lyophilised peptides: storage and shelf life. Buy IGF-1 LR3 in the UK with free tracked delivery, dispatch within 1 working day and card payment.

Ordering, delivery and payment

How fast is delivery, and what is the cut-off?

Delivery is free, tracked and dispatched within 1 working day. The line under Add to cart shows today's order cut-off and the usual arrival day. See delivery and returns for the detail.

What's in the box?

What is in the pack is printed on the pack itself. Ask us before you order if you need to know more.

Which payment methods, and why might a card be declined (VPN, 3-D Secure)?

You pay by card on a secure payment page. A card is most often declined when a VPN is switched on, when the bank's 3-D Secure screen is closed before it finishes, or when the bank blocks an unfamiliar merchant. Switch the VPN off, keep the 3-D Secure screen open until it completes, and try again. If it still fails, contact us.
