Hi guys, i am planning a Test E/ tren E cycle. From my last cycle i have still some Test P and Tren A laying around which i want to use up. Obviously i can not just use all short esters up and switch to long esters same dosage. Longer esters have longer half lifes which would result in a serum level drop, i am trying to avoid that. Online i found the following half lifes: Acetate 1 day Propionate 1 day Enanthate 5-6 days i tried to come up with a solution for a long time. Now used excel to calculate blood serum levels and show them in a diagram. The Photos can be found here: Does this look ok to you guys or did i make a misstake somewhere? First one is to more or less test the solution i have come up with. Works pretty ok, half serum concentration is reached within the requiered time. The Doses are not in mg but relative (so bost esters reach equal serum levels. They later must be multiplied by the requiered dosage. What do you think?
