I have always been of the belief that the loss of libido was related to the less androgenic nature of 1-Test, and not estrogen. Numerous studies have shown non-aromatizable steroids, like DHT, to support libido.
I've never noticed lethargy, well above the ususal level anyway, on any steroid, aromatizing or not. I thought it an odd link, but its acceptance made me think I was just not sensitive to it. Interesting idea.
Infrequent reports of nipple sensitivity even though it shouldn;t aromatize, intrinsic irritation, inexplicable lethargy.. The is one odd little steroid here....
