well just to share, i jumped on the trt wagon about 3 years now, didnt really get my test blood work check but reckon since i'm in my mid-forties, decline in test level is bound to happen anyway although i feel fine and all. mine's a very low dose self-administered 75mg Sustanon per week. started out at 150mg and finally figure out 75mg is the sweet spot for me and best thing is my nuts still retaining the size. alot of folks i know they claimed to be on trt but their dosage is almost equivalent to a cycle.. dont make that mistake. imo, if you are at that age where test level will inevitably decline then u can seriously consider trt, otherwise like they said, make changes to your lifestyle and train hard. so there you go.
