For some reason I can log on, but everytime I try to post or send a PM I get the "this is for platinum members only page"
As for your question, good thing you asked. I think it's a very bad move. Creatine causes electrolyte balance to shift(that's why it's advised to drink plenty of water and get more potassium). Clen does the same thing but to a higher degree.
Creatine "drains" water in your body and Clen is extremely dehydrating.
It's a bad idea alltogether, and I wouldn't be suprised if you tear a muscle.
Now, I'm intrigued as to what kind of muscle spasms you with get on this combo. Ouch.
