In their own words
“I can't do anything with 1 3 dimethyl anymore because I crash waaaayyyy too hard. Like, I would sleep 12+ hours.”
“Jack3d though would give me lots of anxiety.”
“It was in the original jack3d... I wound up with erectile dysfunction (at 25 years old) that took several weeks to recover from.”
“I on the other hand would HIGHLY recommend DMAA... makes me very relaxed, focused, and energetic... I would skip the DMAA”
“Jack3d is okay, I guess. It never really did much for me... I had some great gains on it but it is really easy to build up a tolerance to it”
