Human Long Arg3 Insulin-like Growth Factor-I (Long-R3-IGF-I) is an 83 amino acid analog to human IGF-I. It has the complete human IGF-I sequence with the substitution of Arg for Glu at position 3 (hence R3), and a 13 amino acid extension at the N-terminus.
IGF-1 Long R3 is a synthetic analog of the naturally existing insulin growth factor (IGF) which is a 93 amino acid residue. Modifications of the natural form occurred with the substitution of the Arg with Glu at the position 3, giving a code R3, and also an extension of a 13 amino acid at the B-terminus. Just like the IGF-1, R3 has been shown to induce the development and growth of cells.

Long R3 IGF-1 is significantly more potent than IGF-1. The enhanced potency is due to the decreased binding of Long R3 IGF-1 to all known IGF binding proteins. These binding proteins normally inhibit the biological actions of IGF's. When IGF is active it behaves differently in different types of tissues. In muscle cells proteins and associated cell components are stimulated. Protein synthesis is increased along with amino acid absorption. As a source of energy, IGF mobilizes fat for use as energy in adipose tissue. In lean tissue.,br>
The most effective length for a cycle of IGF is 50 days on and 20-40 days off. The most controversy surrounding Long R3 IGF-1 is the effective dosage. The most used dosages range between 20mcg/day to 120+mcg/day. The dosage issue mainly revolves around how much money you have to spend, plenty of people use the minimum dosage of 20mcg/day and are happy with the results. IGF is most effective when administered subcutaneous and injected once or twice daily at your current dosage. The best time for injections is either in the morning and/or immediately after weight training.

* Shuttles nutrients directly into cells and muscles for maximum results.
* Builds muscle mass, promotes fat loss.
* Increased protein synthesis.
* IGF mobilizes fat for use as energy in adipose tissue.
* Causes hyperplasia, the increase of more muscle cells.
* At a genetic level it has the potential to alter an individuals capacity to build superior muscle density and size.
* Possesses the ability to rehabilitate damaged cartilage.


Storage: Although it is stable at room temperature for up to 3 weeks, lyophilized Long-R3-IGF-I powder should be stored below -20°C. Upon reconstitution, Long-R3-IGF-I solution should be stored at °C for less than 7 days and below -20°C for longer time. Repeat Freeze-thaw cycles should be avoided for Long-R3-IGF-I solution.
Reconstitution:
It is recommended to reconstitute the lyophilized Long-R3-IGF-I powder in acetic acid or sodium chloride. This reconstituted Long R3-IGF-I solution can be further diluted to other aqueous solutions.
