Estrogen is essential for any androgen, test or dht, to be active in the CNS and because 1-ad is inactive in the CNS on the first dose (i believe this is true for most) than I think it is some unexplanable reason why this drug doesn't stimulate the CNS, and if it doesn't stimulate the CNS, PA's explanation posted below also makes no sense.
btw, the lethargy and libido problems are two different issues.
Here is what PA said about the lethargy.
Patrick Arnold : "
I don't think its lowered estrogen that makes you lazy because otherdrugs that lower estrogen don't do this. Its probably something we just don't completely understand. It may havesomething to do with high androgenic stimulation in the brain depletingsome neurotransmitters or something. I think some other very highandrogenic steroids also tend to just zombie you out too (includingmibolerone, which DOES aromatize)Maybe stuff like tyrosine, acetylcholine precursors, l-dopa, andsimilar brain supplements might help this. would be interesting tofind out"
