you didn't keep any of your gains on your first cycle cause you have no base whatsoever.
build a base first. you are no where near ready for AAS.
you need to work out 3 years straight before even thinking about AAS.
I am your height and I was once your weight too.. actually when i was a powerlifter in HS i was in the 129 weight class.. i bulked my way up after high school and worked out for 10 years before messing with AAS. atleast get into the 160's. today I stand at 183, see pic.
you are light years away
