Hello everyone!

for a cycle consisting of test e/deca and dbol when is the best time to use hcg and what dosages? some guy at my gym said you should never use pregnyl during a cycle because it messes up your hormones?! while on the other hand I have read that if you use 250 IUx2 of HCG twice a week on cycle it can help in keeping ur balls big! and help to prevent PCT crash or HCG should only be used after cycle and if after cycle which is best time after last day of cycle to take it and at what dosages?thanks again for your time
