Bulking Stack (1 month)


in stock



Bulking Stack Products:

LGD-4033 (Gain) and RAD140 (Premium Anabolic)

Cycle: 4 – 6 weeks

Stack duration: This stack will last up to 25 days or just under 4 weeks.

Dosage: LGD-4033, 10mg per day in the morning. RAD140, 10mg per  day in the morning

Post cycle: 4 weeks PCT Clomiphene at 25mg per day for 4 weeks.

Stack Summary:

Combining LGD-4033 with RAD-140 is without question one of the most exceptional bulking combinations that one can undertake.  The fact that a user only needs to run two products both dosed each morning also makes this combination an easy one to implement.

Subjects will see excessive increases in strength and gains that are lean and clean, enhanced muscle mass and hardness as well as tightened skin around the muscle.

The only notable side effects as with any performance enhancing SARM would be some slight suppression coming off cycle which can be addressed simply with a basic post cycle as mentioned above.
