Human Growth Hormone Peptide 1mg/vial Lean Muscle Building IGF-1 LR3
Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1).It differs from native IGF-1 in that it possesses 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"), for a total of 83 amino acids (relative to the 70 of IGF-1). The consequences of these modifications are that IGF-1 LR3 retains the pharmacological activity of IGF-1 as an agonist of the IGF-1 receptor, has very low affinity for the insulin-like growth factor-binding proteins (IGFBPs), and 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 20-30 hours (relative to IGF-1's half-life of about 12-15 hours).

Why is this IGF-1 important for a bodybuilder or athlete? Let’s take a look at the list:
Helps regulate fat for use as energy, resulting in fat loss.
Contributes to anti aging. As we get older, IGF-1 production slows down and this results in cell reduction. Low levels of IGF-1 are linked to heart failure, lower brain cell regulation and neuron function. Not to mention muscle tissue breakdown.
Helps to increase nutrient shuttling (protein synthesis).
Increases regenerative functions of nerve tissues.
Boosts the ability to cause hyperplasia in muscle cells resulting in fuller muscle tissue.
So increased potency, increased muscle retention... what else?
Well it increases the effectiveness of an anabolic cycle, this is because of a very unique quality of igf-1-lr3, you see IGF-1 acts on several different tissues to enhance growth. IGF1 belongs in the ’superfamily’ of substances known as ‘growth factors,’ along with epidermal , transforming; platelet derived fibroblast, nerve, and ciliary neurotrophic growth factors. None of the other factors have any bearing on exoskeletal tissue incidentally; however, these agents all have in common the ability to stimulate cell division, known as mitogenesis, and cell differentiation. Meaning That In the case of IGF1 which does act on muscle tissue it will initiate the growth of new muscle fibers, and subsequently new receptors for testosterone. Many Users on forums have unanimously concluded that it enhances cycles of steroids significantly. They also seem to be adamant about its ability to reduce fat and improve vascularity a great deal.
Another surprising effect that remains largely unexplained is that it actually Reverses testicular atrophy. Testicles if shrunken will return to “full swing” as it were even in the middle of a steroid cycle. If not shrunken they will not shrink during the cycle. This may explain partially why gains are kept after the cycle. The increased circulating levels of IGF seem to prevent shrinkage and allow for increased LH output post cycle.
How Does IGF-1 Work?
Of course, the liver can synthesize IGF-1 and it can package it with various binding proteins. It then makes it ready for transport into the blood. There are a couple of different variants when it comes to IGF-1 and these are all produced in the muscle. One of them is called the mechano growth factor and this plays a role in how much muscle you can gain over a set period of time. It works by spurring the activity of other muscles and these are called satellite cells. These help to repair any damaged muscles and this is what you would normally experience when you do exercise or when you train. In fact, if you do a lot of weight training then you may stimulate the release of IGF-1 in your muscle but when you take a look at myostatin, you’ll find that this prevents muscle from growing and this is all because of the satellite-cells and their own proliferation.
Differences Between LR2 IGF-1 and LR3 IGF-1:
While lr2 igf-1 and lr3 igf-1 are structurally and molecularly similar, the two should not be confused. A primary difference is r3 igf-1 is predominately found in adult animals while 1gf-1 is found in younger animals still developing the body systems. Igf-1 has the most effect on the growth of muscle tissue as well as the repair of the tissue. It has a very short half-life, lasting only about 20 minutes.
The lr3 igf-1 peptide was developed for research over the long term as it helps to prevent the binding proteins in the blood from being deactivated. Igf-1 for sale in laboratory testing allows the half-life of the peptide to be extended up to 20 hours and enables more effective testing with the longer period of time. Experiments which require more than one round will benefit from the longer half-life.
