Viking Labs MK-677

Viking Labs MK-677 (Ibutamoren Mesylate) is a research compound that acts as a selective growth hormone secretagogue. It mimics the action of ghrelin to stimulate the release of growth hormone (GH) and IGF-1. Each capsule contains 15mg of MK-677 along with 5mg of Piperine to enhance bioavailability.

No, MK-677 is neither a steroid nor a SARM (Selective Androgen Receptor Modulator). It is a growth hormone secretagogue that works by stimulating the pituitary gland to produce more growth hormone without affecting androgen receptors.

MK-677 mimics the action of ghrelin, the ‘hunger hormone’, and binds to ghrelin receptors in the brain. This stimulates the release of growth hormone (GH) and IGF-1 from the pituitary gland, supporting various physiological processes including muscle growth and tissue regeneration.

No, MK-677 does not suppress natural testosterone production. Unlike anabolic steroids or some SARMs, MK-677 acts on the growth hormone pathway and does not interfere with the hypothalamic-pituitary-gonadal axis that regulates testosterone.

Piperine, derived from black pepper extract, is included at 5mg per capsule to enhance the bioavailability of MK-677. Piperine inhibits certain metabolic enzymes, allowing more of the active compound to be absorbed and utilised by the body.

Each bottle of Viking Labs MK-677 contains 60 capsules, with each capsule providing a 15mg dose of Ibutamoren Mesylate plus 5mg Piperine.

As this is a research compound, usage should be based on your individual research protocol. Always follow the guidelines provided with the product and consult relevant research literature for appropriate dosing information.

MK-677 targets the growth hormone secretagogue receptor (GHSR), also known as the ghrelin receptor. By activating this receptor, it stimulates the anterior pituitary gland to release growth hormone, thereby increasing both GH and downstream IGF-1 levels.

Viking Labs MK-677 is described as a research-grade compound designed for advanced and long-term research goals. The precise 15mg dosing format and enhanced bioavailability formula make it suitable for controlled, extended research investigations.

Viking Labs MK-677 is produced by Viking Labs (viking labz), a brand specialising in research-grade compounds. The product is available exclusively through authorised retailers such as Cross The Limits UK.
