hi
even the smallest amt of T will shut your natural T level down, this is why it makes no sense to taper.
HCG is needed to "blow your balls up", not sure what it's medical term is....lol!
Being low in T (natural or not) lowers libido, increasing T naturally would increase libido.
are you taking less T now than you were before? You may have adjusted to a higher level and need that same amount to reach normal horniness.
...or maybe you need a new girl...lol...jk
