the difference in what sense? the esters, half life, molecular weight, viscosity, other?
prop half life is like 48hrs
cyp half life is like 6 days
enan half life is like 7 days
Prop is great, it may be painful to you - depends on lab.. to me 300mg of Prop is like 500 of Cyp/Enan.. I prefer Enan over Cyp, Cyp kept me a bit more bloated than Enan.
Another thing to note is that 100mg of Prop is like 98mg of Test.. Cyp is heavier than Enan so there is a little bit more test in Enan than in Cyp..
