Its hard to fine a straight answer to this, but take what you want from the following:
I've seen ACTIVE-life reported as low as 3 days.
I've seen half life reported as low as 24 hours for acetate.
I've also seen half-life reported as 2 and 3 days for acetate, and 3 and 4.5 days for propionate. General rule, inject at half the half-life.
Acetate ester has 2 carbon atoms, propionate has 3. Enanthate has 7 carbon atoms as a reference point.
You'll come across a number of forums that have this list that is wrong saying that propionate has a shorter half-life than acetate. That is not true.
Honestly, the most convincing is the endless accounts of sides being much worse when people switch to EOD constantly coming in and out of being "on" trenbolone, as opposed to providing a steady stream which leads me to always think that ED is best for it.
