Dragon Pharma IGF-1 LR3 1 mg Long R3 Research Peptide Vial

Dragon Pharma IGF-1 LR3 1 mg Research Vial

IGF-1 LR3 is a modified insulin-like growth factor 1 with two deliberate changes: glutamic acid is replaced by arginine at position 3, and 13 extra amino acids are added, giving 83 residues against the 70 of the natural hormone. Those edits weaken its binding to the IGF binding proteins that normally mop the hormone up, so the peptide stays active for much longer than endogenous IGF-1. It sits downstream of growth hormone, which is why it appears in the same research conversations as the secretagogues.

How IGF-1 LR3 Works

Growth hormone raises IGF-1, and IGF-1 is the signal that drives nutrient uptake, protein synthesis and cell growth in muscle and other tissue. Because the LR3 version largely escapes the binding proteins that regulate the natural factor, its effects are stronger and longer: reference material gives about 20 to 30 hours, while the same source infobox lists an elimination half-life of 56 to 72 hours, against roughly 12 to 15 hours for natural IGF-1. That disagreement is reported as a range rather than resolved. The peptide works in a different place from the Ipamorelin or GHRP-6 route, which ends upstream at growth hormone itself.

Reconstitution & Research Use

Add bacteriostatic water down the glass wall and swirl, never shake. One milligram reconstituted with 1 ml gives 1 mg/ml, so 0.1 ml holds 100 mcg and reads as 10 units on a U-100 insulin syringe; 20 to 50 mcg is therefore a very small draw and a low-dead-space syringe matters. Vendor and community material describes a single daily dose, often after training, over four to six weeks, and warns that IGF-1 sits in the same regulatory class as growth hormone. Reported class concerns are hypoglycemia, joint pain and fluid retention.

Quality & Authenticity

Each batch is produced under GMP conditions and checked by HPLC, with a Certificate of Analysis held for the batch. Keep the powder cold and dark, and do not freeze and thaw the mixed solution.
