normal sex drive mid cycle??

Ive been on 500mg of test for 6 weeks and ive had a higher sex drive and frequent erections but about a week ago my sex drive has gone back to normal. is this supposed to happen cuz i just started a new vial so i hope the gear in the new vial is not underdosed.

i think its normal. i notice my "drive" fluctuates thru the cycle.

Yeah it is normal ..... your messing with your hormones ... everyone is differnt though
