Testosterone levels on and off cycle
 

After doing a cycle of Test and PCT, I realize it may take 4 months to have normal test levels again. Will doing a cycle of Test affect my natural testosterone levels for the future of my lifespan? Like will my natural test levels never be good again, so I will always have to be cycling on and off for many years/ Or need TRT?
Any additional info and recommendations would be appreciated. Thanks!

how old are you?
how long you planning your cycle if norm 10-12wks dont think would take 4 months
