forget about the weight. don't focus on that. focus on a body recomposition. but you're pretty lean already.... 10%? i mean, people's estimates can vary quite a bit, and usually people estimate a bit lower than they really are, but i think around 8-12% is just about right for most people, depending on your individual body composition.
that's pretty lean and is a good look for most people.
for the first cycle i would think that four or five hundred mg of test enanthate for 12-14 weeks would be good.
get Aromatase inhibitor (AI) on hand, and pct on hand before you start. i've been hearing a lot of good things about toremifene citrate. i'm going to go with that for mine. i had clomid and nolva on hand but will probably go with just toremifene.
anyway, yeah. like i said, on the primo, when you run it in the future, run at least 600mg/week in my opinion. i just ran it for about 16 weeks and loved it.
that was my first cycle btw.
