Muscle Twitching/Spasms from cycle?

[stack_it]

This happens to me Without cycling. It gets annoying but eventually goes away. I just figured it was from vigorous excercise.

^^ same here, generally in the delts, tris and quads. Sometimes it goes for minutes.

No idea why...

I started running EC stack along with cycling, and I read higher amounts of caffeine could cause it. So idk this may be somewhat of a culprit.

That and like you mentioned above, vigorous exercise.
