if you are on test and controlling e2, your libido will be high. only if you ran a higher nandrolone than testosterone dose would your libido go down. period. i guess if on a 19-nor and prolactin shot up that might cause a decrease too but if you know what youre doing you wont have trouble with libido. oral only cycles are a thing of the past. as long as the cycle doesnt go past 12-16 weeks, a basic pct will bring your testosterone numbers back up to natural levels. clomid is the key. it kickstarts hpta.
