IGF-1 sits in the peptide hormone and growth factor class alongside growth hormone and its releasing factors. The analogues are named so that there is no argument about whether a modified molecule is covered. The class is prohibited in and out of competition. Mecasermin, as an approved IGF-1, is also prohibited without a therapeutic exemption.
Thymosin beta-4 and its derivatives appear in the same class.
The 13-residue extension and the arginine at position 3 give LR3 a tryptic fragment pattern different from IGF-1. After extraction from plasma or urine and digestion, the extension-containing fragment is a marker found only if the analogue is present. The intact analogue at about 9,111 daltons can also be detected directly on high-resolution instruments. The window depends on clearance, which for a binding-protein-resistant molecule is short.
Immunoassays raised against IGF-1 bind LR3 to a degree that varies with the antibody epitope, which makes them unsuitable for confirming the analogue specifically and is also why clinical IGF-1 results in anyone exposed to it would be uninterpretable.
Because the regulatory status of the molecule and the analytical facts behind its detection are part of what is established about it. This page states them; it is not advice.
IGF-1 LR3 is supplied by REVIVE LAB UAE for laboratory research use only, with identity and purity documented for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
