Viking Labs MK – 15mg x 60 Capsules

Viking Labs MK-677 (Ibutamoren Mesylate) is a cutting-edge research compound designed for those seeking powerful support in growth hormone pathway studies, GH axis investigations, and tissue regeneration models. With a precise 15mg dose of MK-677 per capsule and the inclusion of 5mg Piperine for enhanced bioavailability, this formula offers a controlled-dose research format ideal for advanced protocols.

MK-677 is not a steroid or a SARM but a selective growth hormone secretagogue that mimics the action of ghrelin and stimulates the release of growth hormone (GH) and IGF-1 without suppressing natural testosterone production. Viking Labs delivers a pure, research-grade compound to assist in your most demanding and long-term research goals.

Ingredient Breakdown

MK-677 (Ibutamoren Mesylate) – 15mg
MK-677 is known for its ability to significantly elevate GH and IGF-1 levels in the body over extended periods. It acts on the ghrelin receptor, promoting growth hormone release from the pituitary gland, which may support muscle hypertrophy, improve recovery, enhance fat metabolism, improve sleep quality, and even promote skin and connective tissue health in various models. It’s often explored in anti-aging and body composition research for its long-acting and non-inhibitory properties.

Piperine (95%) – 5mg
A bioavailability enhancer derived from black pepper extract, Piperine improves the absorption of many compounds, including MK-677. By increasing gastrointestinal permeability and reducing enzymatic degradation, Piperine ensures that each dose of MK-677 is delivered efficiently and consistently in research applications.
