Verified Is this stack beginner-friendly?
Yes, but start small. It’s designed for gradual, quality progress rather than overnight bulk.
How does this stack support muscle growth?
MK677 helps you recoil from heavy training. Most of the muscle fiber building can be attributed to LGD4033. Combining both will prevent you from stalling so significant progress can be achieved.
Can I use it for cutting?
You can. It’s made for lean mass, so with a calorie tweak, it works fine in a recomposition phase.
