MK-677 Ibutamoren [Powder]- Product Details

What is MK-677 Ibutamoren Powder?

MK 677, also known as Ibutamoren, is often mistakenly categorized as a selective androgen receptor modulator (SARM). While SARMs are compounds being researched for their potential to promote muscle growth and fat reduction, animal studies have shown that MK 677 acts as a ghrelin mimetic. It potentially works by binding to ghrelin receptors in the brain, stimulating the release of growth hormone (GH). Therefore, although MK 677 produces similar effects, it differs from SARMs in its mechanism of action, as it primarily targets the brain’s ghrelin receptors rather than androgen receptors in muscle and bone tissue.

    The mk works great, it is extremely hydrophilic and rather quickly congealed into a gooey blob, even with silica packets. My next batch i am putting into capsules immediately. It also tastes terrible, but whatever.
