Description: IGF-1 LR3 is an analogue of human IGF-1 (Insulin-like growth factor).
IGF-1 LR3 is a recombinant human polypeptide chain of 83 amino acids. It is an analogue of human IGF-1, consisting of the complete human IGF-1, replacing the sequence Glu (E), the Arg (R) at position three. The structure has also added 13 amino acid for extension of peptide according to the N terminus. Overall, it is more biologically active version of the original IGF-1.
This analogue was created with a clear objective - to increase biological activity. IGF-1 LR3 is significantly more effective than IGF-1. The increased efficiency is provided by reducing the bonds of IGF-1 LR3 for all IGF binding proteins. These usually inhibit the biological effects of IGF.
IGF-1 is a growth factor resembling insulin. It is a natural substance that is produced in the human body and reaches the highest level in puberty. It is responsible for the natural muscle growth that occurs over the years of adolescence. In addition to hypertrophy of muscle IGF-1 has one outstanding feature and that's its ability of the muscle fibre hyperplasia. Word hyperplasia represents an increase in body overabundance of individual cells. That is, the number of muscle fibres in the muscle increases. This is a unique feature that can help you get extremely large muscles.
Advantages of the use of IGF-1 LR3:
The optimal and safe dose of IGF-1 LR3 is 20-50 mcg daily. Higher doses may be used, though you risk reduction in sensitivity of IGF-1 receptors. Therefore, recommended are shorter cycles of use (four weeks). Properties of IGF-1 LR3's are ideal in combination with the AS (anabolic steroids), and also in the PCT (period from the completion of the steroid used to start the cycle, own production of testosterone and growth hormone).
