Description
Xcel Pharma XP – LR3 contains Recombinant IGF-1 Long R3 (IGF-1 LR3), a modified form of insulin-like growth factor-1 designed to have a longer biological activity than native IGF-1. It is widely discussed in peptide and sports-performance research because of its role in growth and anabolic signaling.
Each vial contains 100 mcg of IGF-1 Long R3, with the product supplied as a five-vial pack along with bacteriostatic water ampoules.
Benefits
- Contains recombinant IGF-1 Long R3
- Studied for anabolic and growth-related signaling
- Involved in research surrounding muscle-cell growth and protein synthesis
- Longer-acting modified IGF-1 analogue
- Convenient 100 mcg vial presentation
- Five-vial pack
- Includes bacteriostatic water ampoules
- Manufactured under the Xcel Pharma brand
Product Overview
XP – LR3 contains Recombinant IGF-1 Long R3, a modified analogue of human IGF-1. The Long R3 modification changes its interaction with IGF-binding proteins and is intended to extend its biological activity compared with naturally occurring IGF-1.
IGF-1 is an important signaling molecule involved in cellular growth, development, and anabolic processes. Because of these biological functions, IGF-1 LR3 has attracted interest in laboratory research involving muscle cells, metabolism, and tissue-growth pathways.
IGF-1 is also involved in glucose regulation, meaning compounds that influence IGF-1 signaling can have significant physiological effects. Potential concerns include changes in blood glucose and other metabolic effects. This product should therefore be approached as a hormone-active research compound rather than a routine sports supplement.
