Chiming in for the libido part... there`s a lot of variables to that feeling. But when it comes to AAS, Testosterone is Testosterone, the ester only delays the breakdown which controls levels and stability over time. If you haven`t felt like your libido has increased with what you did before, it`s really just your genetics and dosage. I have a sweet spot for libido that`s too high for TRT and too low for cycling. Roll the dice and snake eyes... good luck man.
