6-8 weeks followed by a 4-week break
Dietary supplement use only
For experienced users only. Monitor response closely and consider PCT.
The bundle includes YK-11 (Myostine), Ligandrol (LGD4033), Testolone (RAD140), and Ibutamoren (MK677) – the ultimate bulking stack.
Advanced users typically gain 20-30 pounds of muscle during a 6-8 week cycle with this powerful stack.
No, this is an advanced stack for experienced users who have completed multiple SARM cycles and understand their response.
While generally well-tolerated when used responsibly, some users may experience mild effects such as increased appetite, water retention, or temporary fatigue. It’s important to follow recommended dosages and monitor your body’s response throughout the cycle.
Use a substantial caloric surplus with high protein intake (1.5g per lb bodyweight) to maximize the muscle-building potential.
Ran the Bulking bundle With RAD-140 at 10mg, MK-677 at 10, LGD-4033 at 10 and YK-11 at 5 (since its strong). Strength kicked in surprisingly fast and MK-677 made me enjoy eating bigger portions. Honestly pumps from this bundle were crazy, no other sarm or stack made me look like that. But this stack definitely on the stronger side with some previous experience needed!
I was skeptical at first, but my order got sent the next day and even arrived only 6 days later in UK.
A read a lot of bad experiences here.. but I got my supplement delivered in 9 days to middle of nowhere. I am very saticefied
