IGF-1 LR3 (1 mg Vial)

IGF-1 LR3 1 mg research vial

IGF-1 LR3 is the Long R3 analogue of insulin-like growth factor I. Its structure includes an N-terminal extension and an arginine substitution at position 3 of the IGF-I sequence. This product’s 1 mg figure is total material per vial, not a concentration or a suggested administration amount.

Why LR3 and DES are separate listings

Long R3 and DES are different IGF-I analogues. Early primary research compared their interactions with receptors and IGF-binding proteins in cell systems, with responses depending on the experimental model. Those distinctions are relevant when choosing material for a defined laboratory method. Read the original Long R3 analogue study.

Check whether your study specifies LR3, DES or another IGF-I material. Equal milligram labels do not establish equivalent structure or biological behavior. The comparison link above opens the separate DES listing, while the LR3 research guide covers identity, study context and evidence limitations. Neither listing is a substitute for a prescribed finished medicine.

For scientific background and sources, read the IGF-1 LR3 research guide.

LR3 or DES? This listing is IGF-1 LR3, 1 mg per vial. IGF-1 DES 1 mg is a different analogue sold separately. A matching vial amount does not make the materials interchangeable. Check the identity required by your study.
