And if i stacked it with another long Test ester as Enanthate, i stopped both at 10 week and continued with Test Prop of 100mg/ED for the remaning 2 weeks, before start PCT. I think this is more effectiveness protocol.
Deca need minimum 21 days for half life to clear. Personnally think that deca needs to be stopped full 4 weeks before starting PCT.
If you used to prop in the 2 weeks and started PCT right after (3 days) it was too soon.
