I completed my first fina cycle 6weeks ago and, despite my gains, will never use it again for this exact reason. I posted your question on several boards and tried everything that was recommended: cranberry juice, cranberry extract, milk thistle, oceans of water, potassium from both bananas and in pill form. It got to where I couldn't sleep at night. Cramps kept waking me up. No other AS does this to me (I've never tried d-bol but hear it causes cramps too.) Even tried taking a week off. When I started up again, the cramps returned. I finished my cycle using only 50mg eod.
