IGF-1 LR3 / Acetic Acid Bundle

IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a synthetic analog of human IGF-1 engineered for extended stability and enhanced receptor binding. This version includes an acetic acid buffer (0.6% AA) designed to help stabilize the peptide after reconstitution versus using bacteriostatic water (BAC-water), which some anecdotal sources claim may lead to more rapid degradation. Supplied as a highly pure, lyophilized powder plus acetic acid buffering agent. For laboratory research use only — not for human or veterinary applications.

Key Features

• Peptide Component: IGF-1 LR3

• Peptide Structure: 83 amino acids; Arg3 substitution; 13-amino acid N-terminal extension

• Molecular Formula: C400H625N111O115S9

• Molecular Weight: ~9111 Da

• Form: White to off-white lyophilized powder

Intended Research Applications

• Studies of cellular proliferation, growth signaling, and protein synthesis

• Exploration of metabolic regulation and nutrient uptake

• Investigations of tissue repair, hypertrophy, and recovery models

• Preclinical evaluation in muscle, soft tissue, and regeneration research

Stabilization & Reconstitution Notes

• Acetic Acid Buffer (0.6% AA): Used to reconstitute IGF-1 LR3 to help maintain solution stability, prevent peptide “sticking” to glass, and slow degradation. Many users report that IGF-1 LR3 solutions in AA remain stable for significantly longer periods (several weeks or more) compared to those reconstituted in BAC water.
