Plenty of stim history between E/C, DMAA, DMHA, all the current ones out there. Perfectly comfortable on a bronkaid tab and 200mg caffine. Plenty of experience with yhcl and alpha-y, no issues. This one does contain 5mg yhcl per serving.
Dosed full 3 caps this morning empty stomach, little surprised to get goose bumps and cold sweats off of the 5mg but I did. Nothing too intense, headed to the gym right away. Definitely extra sweating far above average. Energy was comparable to for me E/C stack. Lasted a good 5 hours, no crash. Focus was not great due to the Y hitting so hard but the stim for energy was great. All in the first dosage and first day. Listening to alot of stim junkies on here I would say right up your ally. Also side note only 100mg caffeine also, like a stim break by dosage but together pretty solid.
