you guys have to remember you had to go on TRT cause there was something wrong with you to begin with. the TRT doesn't fix that root problem, it merely covers it up.
so if your problem was libido for example.. going on TRT may or may not help that. cause it isn't a cure for it.
cyp is best injected 2X per week... once a week is okay.. but your levels will fluctuate less at 2X per week. half life is about 2 weeks meaning after 2 weeks half of what you injected 2 weeks ago will be left in the body. and if you injected again a week later then a % of that will be left.
there are sites that will guestimate how much is in your system but you should feel a good bump within weeks with legit cyp. and your levels will stay peaking after weeks 4 or 5.
