Creatin.

[Yasmin]

I used it for a couple of years when I was weight lifing heavily (no pun intended ). It allowed me to recover quicker and work out longer, the "side-effect" was that I got HUGE muscles, it transports more fluid into the cells so you bulk a bit, as soon as the training intensity drops the bulk diminishes.

Thanks for that. I'm hoping to bulk up a bit in the quads so I can push the long, flat stretches harder. So, in theory, if I take creatin & keep working these muscles (& drink lots of fluid) I should bulk here. I'll try it.
