IGF-1 LR3 0.1mg – Precision Dosing for Targeted Results

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1).^[1]^[2] It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence (“arginine 3”), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) (“long”), for a total of 83 amino acids (relative to the 70 of IGF-1).^[2] The consequences of these modifications are that IGF-1 LR3 retains the pharmacological activity of IGF-1 as an agonist of the IGF-1 receptor, has very low affinity for the insulin-like growth factor-binding proteins (IGFBPs), and has improved metabolic stability.^[1]^[2] As a result, it is approximately three times more potent than IGF-1,^[3] and possesses a significantly longer half-life of about 20–30 hours (relative to IGF-1’s half-life of about 12–15 hours).

Take a controlled and precise approach to performance and recovery with IGF-1 LR3 0.1mg, a low-dose option designed for accuracy, flexibility, and gradual optimization.

Known for its extended activity, IGF-1 LR3 works at the cellular level to support muscle development, recovery, and nutrient utilization — making it ideal for users who prioritize precision in their protocol.
