Which is the better supplement for mass gain- Isa-test or ecdysterone (vyo tech 17 hd / thermolife e-bol)?
I like the idea of Isa-test since it’s made by Isatori, and they really stand behind their products (plus have good scientific papers to base their claims), but I have also read some pretty amazing things about ecdysterone. Anyone that has tried both would help tremendously, or a suggestion for a cost-effective supplement.
