The Muscle Stack – RAD-140 + MK-677

The Muscle Stack is a dual-compound research bundle containing RAD-140 (Testolone) and MK-677 (Ibutamoren). The two investigational compounds represent distinct areas of laboratory research involving androgen receptor and growth hormone signaling pathways.

RAD-140 is an investigational selective androgen receptor modulator (SARM) that has been studied for its interaction with androgen receptors in experimental models.

MK-677, also known as Ibutamoren, is an investigational growth hormone secretagogue that has been researched for its interaction with the ghrelin receptor and its relationship with growth hormone and IGF-1 signaling.
