The testes have a lot of aromatase and the intratesticular T levels can be 80 times higher than serum in young normal males. That is a lot of T [substrate] for the aromatase to work on.
250iu hCG EOD is not making the testes create more E2 than for young normal males. It is an HRT dose.
When on TRT without hCG, you have a baseline extrogen production. When adding hCG and the testes come back to life, the estrogen level climbs past that baseline. Nothing unexpected there.
Guys say that hCG increases estrogen… so what! New baseline, adjust your adex. Do not blame adex, blame your testes that are now back on line.
When increasing T by 50%, 2 packs to 3 packs, there is a lot more T for aromatization. T and adex are competitive and statistically oppose each other for aromatization probabilities. More T needs more adex. If you increase T, adex must be increased.
3 drops of ldex EOD is (3x3.5)/28=.375 mg/wk.
8 drops of ldex EOD is 1mg/wk.
Now with E2=41 and a E2 target of 22. Your dose can be scaled as (41/22)*.375=.7mg. That is still a low dose for many.
The above seems to work well for injecting.
For Agel, the aromatase under the skin is seeing huge transient amounts of T over large surface areas. This is a different dynamic when T levels are VERY high under the skin - adex is out numbered at this part of the body.
There will be surges of E production. With surging and decaying E2 levels, the E2 lab results may vary with the time of the blood draw. That would have very little diagnostic value, more of timestamp.
If the testes are still regenerating and recovering T production, then T levels are increasing, which is a moving target for labs and adex dosing in the near term.
If you get to a good endpoint in T and E labs, if you change T levels, it is a new game. You have to balance the results of two greatly different processes.
I think now that it is clear that asking adex to balance with T in internal tissues and dermal layers with transdermal TRT at the same time is like trying to play to games at once. Not as simple as with injections* where the intensity of battle is the same everywhere.
*Yes injections that are once a week create large changes in T and E levels. Many inject more than once a week and changing level issues become less of a concern. Some even inject T EOD.
With transdermals, there may be a weakness to linearly scaling up adex. With transdermals and E spikes, lab results will vary with the time of the blood draws. 24 hour urine tests would then be of value.
I had not thought before about how transdermals add complexity in comparison to injections.
