How long till most people start feeling cyp kick in. I am at 4 weeks. I'm doing 750mg. per week. I am starting to get really good pumps when working out. Not much else though. I am taking 200 mg of upjohn and the rest is syd group. I think the sydgroup is way underdosed. I think i should prob be feeling more taking that much four weeks in. ANy opinions. My diet and workout are in check.
