What is IGF-1 LR3 Peptide?

IGF-1 LR3 is an altered variant of insulin-like growth factor-1; the complete name of the peptide is insulin-like growth factor-1 long arginine 3. All IGF-1 derivatives play important roles in cell proliferation, cell division, and cell-to-cell communication. Despite showing physiological effects similar to the parent protein, IGF-1 LR3 does not interact with IGF binding proteins as strongly as IGF-1. Hence, it stays in the bloodstream for longer durations (about 120 times longer) as compared to native IGF-1. The structural modifications in IGF1-LR3 have contributed to its increased half-life in the blood. The peptide is created by the inclusion of 13 amino acids to the N-terminus of native IGF-1 and by replacing the glutamic acid at position 3 to arginine.

Research

Cell Division
Like IGF-1, IGF1-LR3 acts as a potent stimulus for cell division and proliferation. It primarily affects connective tissues of the muscle and bone and promotes cell division in the liver, kidney, skin, lung, nerve, and blood tissues. IGF-1 is best considered to be a maturation hormone because it influences cell proliferation, differentiation, and maturation, thereby helping them to carry out their specialized functions.
The longer life span of IGF1-LR3 in the blood makes it a much more potent molecule as compared to IGF-1. A single dose of IGF1-LR3 provides about thrice as much cellular activation compared to a similar dose of IGF-1. It is important to remember that IGF-1 LR3 peptide and every IGF-1 derivative do not mediate cellular enlargement (hypertrophy), and instead may participate in cell division and proliferation (hyperplasia). For instance, in the case of muscle, IGF-1 LR3 does not cause enlargement of muscle cells but increases the total number of muscle cells.

Impairment of Myostatin
Myostatin (also known as growth differentiation factor 8) is a muscle protein that primarily suppresses the growth and differentiation of muscle cells. Myostatin is, thus crucial in protection from unregulated hypertrophy and proper healing post-injury. However, some situations that demand inhibition of myosin. Blocking of myosin can be helpful in conditions like Duchenne muscular dystrophy (DMD) or in people who suffer from loss of muscle due to prolonged immobility. In such cases, blocking the natural enzyme could help slow down muscle breakdown, maintain strength, and avoid morbidity.
Studies conducted in mouse models of DMD have shown that IGF-1 LR3 and other IGF-1 derivatives can overcome the adverse effects of myostatin to protect muscle cells and prevent apoptosis. IGF1-LR3, due to its long stability, is highly effective in counteracting myostatin and functions by activating MyoD, a muscle protein that is normally triggered by exercise (e.g., weight lifting) or tissue damage and mediates muscle hypertrophy.

Fat Metabolism and Diabetes
IGF-1 LR3 indirectly boosts fat burning by associating with the IGF-1R receptor and the insulin receptor. These interactions improve glucose uptake from the blood by muscle, nerve, and liver cells. Thus, there is an overall reduction in blood sugar levels, which then triggers adipose tissue as well as the liver to initiate catabolism of glycogen and triglycerides. Overall, this leads to a decrease in adipose tissue and net energy consumption (i.e. net catabolism).
Given its role in controlling blood sugar levels, IGF1-LR3 reduces insulin levels and the need for exogenous insulin in diabetes.  In a majority of the patients, this brings about a 10% reduction in insulin requirements to maintain the same blood sugar levels. IGF1-LR3 thus helps understand insulin regulation in patients with decreased insulin sensitivity. It also highlights possible ways to prevent type 2 diabetes.

IGF-1 LR3 Peptide – Longevity Research
IGF-1 LR3 promotes tissue repair and upkeep of the body, making it a protective molecule against cellular damage and the effects of aging. Research in cows and pigs indicates that IGF1-LR3 administration can overcome the effects of aging, prolong life and reduce disability. Ongoing research in mice has focused on the potential of IGF1-LR3 in preventing the progression of a wide range of conditions such as muscle atrophy, dementia, and kidney disease.

IGF-1 LR3 Peptide – Glucocorticoid Signaling
Glucocorticoids, produced essentially from the adrenal glands, also act as important clinical drugs which help to control pain and decrease inflammation in autoimmune diseases, cancer, and neurological injuries, to name a few. However, glucocorticoids have numerous undesirable side effects, such as muscle wasting, fat gain, and deterioration of bone density. Thus, IGF1-LR3 is being explored as an option to reduce the side effects of glucocorticoids and thereby mediate a more effective therapy. Studies have shown minimal to moderate side effects, low oral bioavailability, and excellent subcutaneous bioavailability in mice.
Per kg dosage in mice does not scale up to the dosage which can be required for humans.

    Would love it if you guys advertised more deals or sales!

  6. Larry Ray Reed

    Your packaging is so neat, I just love staring at it haha

  7. Rolf Steiner

    Fast delivery, excellent product

  8. Aki Kadomatsu

    They take a lot of my companies peptide budget!

  9. Sonia Pierce

    I wish I knew about peptides earlier. I’m relatively new to this area of research, but it has held up my interest tremendously and I thank BP for always making themselves available to answer my questions and teach me all I need to know

  10. Kat Creedon

    They sometimes take a while to respond to emails, but always do eventually. Aside from that, no criticism whatsoever

  11. Sarah Yan

    This product gives great feedback in my experiments. Also great shipping times, was worried that the shipping would take longer or they would take longer to ship the products out but does not seem like it.

  12. Mai Yang

    Have always had a good experience with them. Peptides are consistently top quality and I do notice a change in my research results.

  13. Emmit Coddy

    Was browsing their page and saw they had a pretty good easter promotion! Love myself a deal.

  14. Will Jacobs

    Amazing

  15. Andy Vale

    Customer service is as good as I have been hearing. I had an issue with my order. It seems like they missed a peptide order and sent me double of one of the others. I emailed them but decided it might be a good time to see if I can get a hold of them via telephone. Low and be hold I got in contact with someone right away. I explained to them that i got my order and everything is in. good condition but that they sent me double of one order and forgot about the other completely. I waited on hold for maybe 2 minutes and they came back informing me that they just placed a free order now to be sent over night. Told me to keep the extra that they sent over as well. After we hung up I was surprised to see that they even sent a discount code for my next order.

  16. Alisa Rodrigez

    Ofrecen tantos códigos de descuento y realmente ayuda con un pedido grande. Gracias BP

  17. Annie Haas

    They have blog posts describing every item they now sell. Love this as a quick way of brushing up my information on peptides I don’t know much about.

  18. denny wolfe

    Fantastic business. Vials were all in good condition and looked like their pictures.

  19. Felix Peters

    Great things have happened to me throughout my time working with Biotech. First time I’ve ordered anything from them. Yes, I think they’d benefit from a new package design.

  20. Richard Dail

    My stuff arrived to me in a damaged state! Contacted them and got on the line with Jamie. They were able to handle the situation and had a new batch of peptides ready to be shipped out for me. I couldn’t be happier with both the peptides and the service.

  21. Jen Mones

    I’ve never seen anything run out of stock, and even if it did, it was refilled in no more than two days at most. There’s hardly a lengthy wait for anything here.
