Dear brother, i agree but there is this with my situation, i have restored my libido, visual lust and refractory period with aromatase inhibition but, it did not helped with my ED.
On ed side there are two supplements and one anti-depressant helped me a lot. Methylphenidate XR, Methlyfolate 10mg and Niacin 500 mg per day really helped me. I really do not understand how it happened because as you said i expected to become worse.
Paradoxically, esspacially night time my erections became fuller and harder.
i increased niacin to 1.5g per day because, it binds GABA receptors, it is a Positive allosteric modulator also niacin really helps me with joint pain caused by exemestane.
Methylfolate boosts every neurotransmitter in the brain but, niacin channels more tryptophan to Serotonin pathway so in fact i should be worse on it but opposite is happening.
Also methyl-b12 makes me anxious and nervous i really prefer adenosly-cobalamine or hydroxycobalamine.
