Buy IGF-1 DES (Truncated Insulin Like Growth Factor I). Also known as des(1-3)IGF-1.

Protein IGF-1 DES is a truncated version of peptide hormone IGF-1 (insulin-like growth factor 1) in which the tripeptide Gly-Pro-Glu is absent from the N-terminus end of the protein. In other words, DES(1-3) IGF-1 lacks the first 3 amino acids at the N-terminus of insulin-like growth factor 1, and consists from total of 67 amino acids, relative to the 70 amino acids of IGF-1.

It is naturally occurring endogenous hormone in human and mammals, that has been found in the human brain, cow colostrum, and pig uterine tissue. The amino acid sequence of DES(1-3) IGF-1 is TLCGAELVDA LQFVCGDRGF YFNKPTGYGS SSRRAPQTGI VDECCFRSCD LRRLEMYCAP LKPAKSA.

Scientific research and clinical trials have shown, that the molecule binds with high-affinity to IGF-1 receptor. And thanks to its a much reduced binding to IGF-binding proteins, caused by the absence of the glutamate at position 3 (tripeptide Gly-Pro-Glu at the N-terminus) is even 10-fold more potent than regular IGF-1 in stimulating hypertrophy and proliferation of cells!

Clinical opportunities for IGF-1 DES have not yet been very evaluated, but could apply in catabolic states (using the peptide to induce anabolism in catabolic conditions such as muscular dystrophy) as well as for the treatment of inflammatory bowel diseases. IGF-1 has a strong ability to maintain and build muscle, especially in IGF-1 DES form.

In addition to a direct anabolic effect on skeletal muscle, the production of more IGF-I is also capable of stimulating the proliferation and differentiation of muscle stem cells (satellite cells) – real growth of new muscle cells, and IGF-1 is the only hormone that can do this. The molecule is also a promising candidate for treat of a number of neurological diseases.

Peptides Prefer the Cold

Keep peptide vials refrigerated at all times to reduce peptide bond breakdown. DO NOT FREEZE. Most peptides, especially shorter ones, can be preserved for weeks if careful.

Always swab the top of the vial with an alcohol wipe, rubbing alcohol or 95% ethanol before use.

Before drawing solution from any dissolved peptide vial, fill the pin with air to the same measurement you will be filling with solution, ie. if you plan to take 0.1 ml, first fill the pin with 0.1ml of air, push the air into the vial, and then draw the peptide back up to the 0.1 ml marker. Doing so will maintain even pressure in the vial. Always remember to remove air bubbles from the pin by flicking it gently, needle side up, and pushing bubbles out. In addition, push out a tiny amount of solution to ensure there is no air left in the metal tip.


Only Mix With Sterile Bacteriostatic Water

The purity and sterility of bacteriostatic water are essential to prevent contamination and to preserve the shelf-life of dissolved peptides.

Push the pin through the rubber stopper at a slight angle, so that you inject the bacteriostatic water toward the inside wall of the vial, not directly onto the powder.

Lyophilized peptide should be stored at -20°C (freezer), and the reconstituted peptide solution at 4°C (refrigerated). Do not freeze once reconstituted.


Do Not Shake Vial To Mix

Air bubbles are unfavorable to the stability of proteins.
