Moexis, I had the same problem after my SRS, that's why I'm still on some AA even more than 12 years after it.
It is about genetical predisposition, androgen receptors seem being over sensitive to even those little adrenal
androgens. E hardly helps, if this is the case (I'm still trying to study my personal condition). OTC, some scientifical
publications would suggest that E can actually increase adrenal androgens output.
Please ask your doctor to have them checked (DHEAS and Androstenedione). They will possibly be in range,
but your receptors still too sensitive to them. The fact that your T is 0.28 means nothing.
Do you even suffer some degree of hairloss and/or body hairs other than greasy hairs ?
Progesterone and some synthetic progestogens usually worsen such issues (but NOT CPA, even if it's a progestogen),
however I don't think you may have any meaningful basal P level by your own, if you don't take any P.
Also consider that switching off CPA abruptly may cause some T rebound effects, adrenal fatigue and other annoyances -
even if I think that after 3 months such effects should already stabilize.
You may discuss with your doctor to adjust your E dosage (both loweing or increasing it) to see whether this
has some infuence (both positive or negative). Otherwise, discuss with him the opportunity of taking some low dosage
of CPA or (better) Bicalutamide.
