There are and always will be a few that get a film of water under the skin when using creatine. Most don't. I don't see the point for the majority who do not have this issue removing creatine while on any AAS/PED's. More so aas even in untrained nonsupplement using (and non competitive too) they average about 120g peer 75kg bodyweights of naturally occurring level of creatine. When we add it in swe boost the amount we store.
I also don't like to change too much when I'm on a cycle. This is especially true of first time users of steroids. We see this all the time. Shit diet, shit training and no steroids vs tip top diet, tip top training AND steroids. How about great diet and great training ALL the damn time THEN add in steroids. That way you KNOW what made the difference. It's how it's done in studies. Otherwise you might have bunk gear but the training and diet made all the difference and so on.
With the exception, as above, of a ripped to the bone few days out from competing athlete leave it in.
