TWP Nutrition MK-677 Ibutamoren

MK-677 Ibutamoren

Ibutamoren (MK-677) by TWP Nutrition is a powerful growth hormone secretagogue designed for athletes and bodybuilders seeking to optimise performance, recovery, and physique. Known scientifically as ibutamoren mesylate, it mimics the hunger hormone ghrelin, binding to ghrelin receptors in the brain to naturally stimulate human growth hormone (HGH) and increase IGF-1 levels.

Ibutamoren Mesylate

Elevated GH and IGF-1 can support:

• Increased lean muscle mass and reduced fat mass

• Improved bone turnover and density over time

• Faster recovery and enhanced joint, tendon, and ligament healing

• Better sleep quality, including longer REM phases

• 60 capsules

TWP Nutrition

This formula also includes Huperzine-A, a cognitive enhancer that increases acetylcholine – the “learning neurotransmitter” – supporting memory, focus, and muscle contraction. Ideal for athletes, weightlifters, and those seeking both physical and mental performance benefits.
