It has been a while since I have tried the ECA stack...going to have to give it a shot again. This stack here was really solid, basically I dosed as follows...
2 N2 Burn + 1 N2 Stim (morning)
1 N2 Burn + 1 N2 Stim + 1 N2 Flame (noon)
2 N2 Flame + 1 N2 Stim (afternoon)
I had all day energy, not feeling stimmed out at all, just smooth and clean. During this stack I did drop around 8 lbs, and when the N2 Burn ran out I had some of the other left and stacked it with Forged Burner for about a week...then it was just Forged Burner.
I think this stack would go great with SARMS S-4...that would be a pretty sick summer shred stack for sure!!
