I dont know what the hell he is talking about.
I think this is what he is getting at.
He is wanting to know about the actual percentage of bioavaliable hormone, because as we all know the esterfied molecules of testosterone are inactive and will not bind to the androgen receptor in great amounts with the esters attached.
So if you take the molecular weight of the esterfied Test minus the molecular weight (MW) of free testosterone you get X amount of potential hormone in the body. We then use this number to back convert to MG/ML of testosterone to find the actually amount of testosterone that will be circulating from each shot assuming 100% de-esterification in the body.
I think i rambled that out ok, There is a MG converter on here somewhere that shows all this stuff to.
I am not about to sit down and calculate it all out either....
