Buy IGF-1 LR3 Peptide (Insulin Like Growth Factor I Long R3). Also known as Long R3-IGF-1 and IGF-1 Long R3.
Synthetic peptide IGF-1 LR3 is lengthened analogue of endogenous peptide hormone IGF-1 (human insulin-like growth factor 1). Unlike regular IGF-1, its prolonged version IGF-1 LR3 haves an arginine instead of a glutamic acid at the third position in its amino acid sequence (“arginine 3”), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) (“long”). Total length of its amino acid chain is 83 amino acids unlike 70 amino acids of regular IGF-1.
IGF-1 LR3 still retains its strong pharmacological activity as an agonist of the IGF-1 receptor, but due to the mentioned modifications has very low affinity for the insulin-like growth factor-binding proteins (IGFBPs) unlike regular IGF-1 does have, and also has improved metabolic stability. As a result, it is approximately three times more potent than IGF-1, and possesses a significantly longer half-life of about 20 hours. The amino acid sequence of IGF-1 LR3 is MFPAMPLSSL FVNGPRTLCG AELVDALQFV CGDRGFYFNK PTGYGSSSRR APQTGIVDEC CFRSCDLRRL EMYCAPLKPA KSA.
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.
