Cyp has a longer half life but slightly less hormone per MG. Like 2mg per 100 when you remove the ester.
So 100mg of your cyp is actually 70mg of actual hormone where enanthate would be like 72mg.
Placebo, how many cycles you've done (diminished returns) , if it's accurately dosed. These are what might make you believe that cyp or enanthate worked better.
Honestly if you ran 500mg of each, that's accurately dosed, in the same circumstances, you wouldn't tell a difference.
Enanthate can cause more cases Of PIP though due to the ester. That's One reason why Dr's use cyp.
