what is the science in that ? i see a lot of "gurus" handing out cycles for ex: test c 250mg eod with test prop 100mg ed
Depending on the ester, each compound has a varying amount of bioavailable testosterone in MG after injection. If injecting 100mg of Prop there is about 83mg of testosterone available, versus cypionate which, per 100mg is about 71mg testosterone available.
In addition, the esterases in the body break down Prop faster than cypionate and make more testosterone available to be absorbed. The longer the ester, the longer it takes for the testosterone molecules to be absorbed and the less available.
I’ve done what you refer to a few times during blasts, and had great results. The Prop hits you faster (I think peak levels at 12 hours post injection) and helps stabilize blood levels while the esterases are working on the cypionate to be absorbed.
When I did it, I was pinning 375mg cypionate EOD and 100mg Prop EOD. Not recommending you do this though.....
