It's superuseful if you want to use high dose of DHTs (DHB,Proviron,Masteron,Primobolan,..), since it kills all high DHT sides.
For growth i will stack it like that:
GW50156 (10mg 2 weeks 20mg 4 weeks; 4 weeks break; repeat)
LGD 4033 (10mg 4 weeks; use it when taking a break from RAD140; 30 days break; repeat)
RAD140 (15mg for 8 weeks)
With added AAS ofc...
