Browns seemd stronger to me than Jins because they made me feel much, much more fatigued. On the other hand, Jins seemed to induce greater fat loss. Go figure.
Hygetropin caused gh fatigue similar to that of the browns, but didn't induce as much fat loss as the Jins. I've very recently added T4 to the mix and the fatigue has subsided almost entirely.
I guess the bottom line is that I'm placing a second order for Hygetrops this week.
