Too vague of a question with too many factors involved with cramping....
Is it just in the muscles trained? At 4 weeks the EQ is really just starting to take effect so I doubt it's that. If you really want help from members you need to give us more info like AAS history, stats, diet, diet changes, training history, other supps used (creatine glutamine BCAA's, ect), fluid intake, caffiene, stimulants, alcohol, beta agonists, outside activity (rec sports), vtamin, mineral, and electrolyte intake, peptides, pathophysiology (medical conditions), blood pressure, Rx meds, and I could go on.....
