Modified GRF (1-29) & Ipamorelin Peptide Blend

Modified GRF (1-29) and Ipamorelin are separate peptides, which may work synergistically and have been studied in combination for their potential impact in growth hormone release and growth hormone pulses. This increase may result in several downstream physiological activities associated with increased growth hormone release. Mod GRF (1-29) peptide is an analog of growth hormone-releasing hormone (GHRH).[1] Similarly, Ipamorelin is suggested to act via binding to growth hormone secretagogue receptors.[2] Generally, GRF has a short half-life that limits its research potential. However, GRF (1-29) has a modified structure with an apparent longer half-life and therefore better research potential. Likewise, Ipamorelin appears to have a high sensitivity to growth hormone receptors, leading to superior research conditions. Combination of these peptides may lead to an increase in growth hormone response compared to control levels.

Mod GRF (1-29) & Ipamorelin Research

Mod GRF (1-29) & Ipamorelin and Gastrointestinal Tract
Research suggests that high circulation of growth hormone may induce positive impact within the gastrointestinal tract, and thereby on inflammatory bowel disease and short bowel syndrome.[3] Researchers report that “65% of [subjects] receiving GH achieved … remission, compared to 20% [given] with CTX alone.” Growth hormone appears to act via Vasoactive Intestinal Peptide (VIP) receptor VIPC1. This interaction may allow the hormone to improve bowel motility.

Mod GRF (1-29) & Ipamorelin and Cardiovascular Function
Myocardial Infarction (MI) is considered to lead to scarring of cardiac tissues and may reduce heart function (such as ejection fraction). Studies in animal models have suggested that growth hormone may accelerate heart tissue repair post-MI, reduce infarct size, improve cardiac ejection fraction, and improve overall cardiac function.[4] The scientists reveal that “Through activation of GHS-R1a, secretagogues produced a positive inotropic effect on ischemic cardiomyocytes and protected them from I/R injury probably by protecting or recovering p-PLB (and therefore SR Ca2+ content) to allow the maintenance or recovery of normal cardiac contractility.”

Mod GRF (1-29) & Ipamorelin and Bone
Research in growth hormone stimulating peptides such as Mod GRF (1-29) and Ipamorelin suggests that these peptides, such as Ipamorelin, when observed in murine models, may potentially completely halt any bone loss triggered by steroids.[5] Moreover, it may potentially trigger new bone formation and increase the Bone Mineral Density (BMD) by up to four-fold.

Mod GRF (1-29) & Ipamorelin and Muscle Cells
Research suggests that growth hormone-secretagogues, of which Ipamorelin is classified, may inhibit the catabolic activity of glucocorticoids on muscles (such as muscle wasting).[6] Mod GRF (1-29) & Ipamorelin peptide combination may have a high growth hormone-receptor sensitivity and act via mechanisms including increased levels of Insulin-Like Growth Factor 1 (IGF-1), leading to muscle cell proliferation.

Mod GRF (1-29) & Ipamorelin and Blood Sugar Regulation
Some research suggests that growth hormone-analogs may increase the number of beta-pancreatic cells, leading to an increase insulin secretion. Calcium-driven channels are considered to mediate insulin secretion from pancreatic cells. Growth hormone-secretagogues such as Ipamorelin may trigger insulin release from pancreatic cells via pancreatic cells’ calcium channels.[7]

Mod GRF (1-29) & Ipamorelin and the Thyroid
Thyroid dysfunction may occur concomitantly with growth hormone disturbances. This is considered often to be the case in conditions involving the pituitary gland, where thyroid dysfunction may be associated with growth hormone deficiency. Researchers have noticed that research models of thyroid insufficiency, when exposed to GRF, appear to exhibit an increase in thyroid support.[9]

    The delivery time took me by surprise. Cannot believe how fast they work

  15. Laura Perry

    Only thing I have to say is wish they would email or have a waitlist or soemthing to notify me when product is back in stock. Other than that I have no other complinats.

  16. Issac Kim

    I wish I discovered you earlier. Would’ve saved me a lot of bad peptides and experiences


    I suggest them to co-workers when they ask for a peptide source referral.

  18. Elija Stevenson

    This blend is simply the best things I’ve ever come across on this site.

  19. Spencer Noels

    No doubt, the best peptide website on the market. The best products and services available.

  20. Matthew Stahl

    Excellent, 11 out of 10 blend, thanks for making this available.

  21. A. McGill

    Every time I make a call, I receive the greatest service. Shipping is lightning-fast. When a product was damaged in shipping, they immediately replaced it with a new one and didn’t ask any questions.

  22. eric paciello

    I tried a couple peptides from them last month as a test run. No things were damaged or lost in the delivery.

  23. Mac Weissman

    I honestly feel like your prices are a bit too high. I understand the price-quality ratio thing, but some of the scores on here are immense. Might wanna reconsider a bit.

  24. Joey Ablouh

    Nice selection of peptides, prices are fair too

  25. Erick Richardson

    This is how you do business. Astonishing quality and amazing prices!
