Some people swear by adding HCG with TRT therapy,
They enforce the DHEA\Pregnenolone , LH and FSH etc... and the fact that they feel that much better using it.
Other don't use it, and also report feeling well.
I prefer NOT using it, having looked at it at length, my impression was that the benefits reported from bi-thereaphy with HCG, the benefits reported are primarily from the testosterone/E spikes that the HCG can give.
To me it means that you still have NOT found your TRT sweet-spot.
I have been using HCG for over 10 years with good results. It does many things besides mood , testicle size, T boost. There is also keeping the P450 pathway open.
Without. Hcg seemed to lead to elevated e2 and water retention (while doing once weekly injects)
Ive recently started emerics protocol and so far i prefer daily low dose injects (10mg/day) with no hcg or ai.
