The problem with this is you really have no idea when the peak occurs due to differences in how people metabolize the T/hcg once it is injected. An injection might hit the bloodstream almost immediately in one person, but take a day or so to metabolize in another.
Not only that, but you wouldn't necessarily take the adex right at the peak anyway since it takes a while for it to kick in and start working. So you would have to take it before the peak. How much before? No clue.
There are too many variables and too much guesswork to really try to hit this moving target. That's why a more constant T dosing protocol is recommended--once you have that squared away with little fluctuation in serum levels, hcg and adex dosing falls into place nicely.
