IGTRIN [IGF-1 LR3 100mcg] contains Long R3 IGF-1, a modified analogue of insulin-like growth factor-1 (IGF-1) designed to remain active in the body for significantly longer than natural IGF-1. Its prolonged activity provides sustained stimulation of the IGF-1 receptor and the anabolic pathways involved in muscle growth, protein synthesis, cellular development, and tissue repair. For athletes and bodybuilders, IGF-1 LR3 is particularly valued for its potential to support muscle development, recovery, and nutrient utilization during periods of intensive training.
Product Benefits
- Muscle Growth Support: Stimulates IGF-1 receptor pathways involved in muscle protein synthesis, cellular growth, and muscle tissue development.
- Anabolic Signaling: Provides prolonged activation of anabolic pathways associated with muscle growth and tissue development.
- Recovery Support: Supports cellular processes involved in muscle repair and recovery following intense physical training.
- Nutrient Utilization: Supports metabolic pathways involved in nutrient uptake and utilization by muscle tissue.
Usage Guidelines
- Research Dosage: Athletic protocols generally range from 20 to 50 mcg per day, depending on experience and tolerance. These protocols are typically divided into conservative, standard, and advanced ranges.
- Cycle Duration: Common protocols use approximately 4 to 6 weeks of administration, followed by a period without use.
- Administration: IGF-1 LR3 is commonly administered by subcutaneous or intramuscular injection. Protocols described for athletic use generally favor once-daily administration, with post-workout use frequently referenced.
Precautions and Wellness
- Possible Side Effects: IGF-1 LR3 may affect blood glucose and can cause hypoglycemia-related symptoms such as dizziness, weakness, sweating, hunger, nausea, or lightheadedness.
- Blood Glucose: Particular attention should be paid to blood glucose levels, especially when using higher doses or combining IGF-1 LR3 with other compounds that influence glucose metabolism.
- Monitoring: Monitor general tolerance, blood glucose-related symptoms, fluid retention, headaches, and joint or muscle discomfort during use.
- Storage: Store the lyophilized product in a cool, dry place and refrigerate after reconstitution. Protect the reconstituted solution from light.
