Well... it increase water retention, and on cycle you are already very prone to that.
it gives more strength more nothing to compare with testosterone boost...
So it seems pretty useless to use on cycle...
I would disagree with you here. Creatine acts as a reserve for ATP. It holds water within the muscle. Creatine with the right dose will not make you retain subq water.So it definitely isn't useless. You can use it year round if you want.
