If you’re training is sufficiently intense, you get enough sleep, and eat well, you will definitely see noticeable results from your first cycle.
I would think 500mg at your size is quite high for a first time blast though, and testosterone is a fairly slow acting hormone so maybe 350-400 over 12-14 weeks might work even better.
Over the years I’ve witnessed a lot of first cycles, as well as my own, and everyone reacts differently, though very rarely have I found someone to be displeased with their progress.
My first cycle of Test was 400mg of Test c per week,and at the time I was in my 30s and weighing 115kg naturally at about 14% body fat. In hindsight if my bf% was lower I’d have no doubt seen more change in the mirror, but still my delts and lats exploded betweens weeks 5-10, and everything slowly started to change for the better, including metabolism, endurance and most notably strength. I never looked back.
My squat bench and dead all increased by 15-25% on my first cycle, and with some thoughtful programming and bit of guidance I learnt to maintain strength gains by altering the volume in line with the tapering hormone levels between cycles. Nowdays I just blast and cruise.
Life is better in every way with higher Test - just make sure you get it from a credible source.
