Dr. Ty, I’m 18 years old and considering starting 200mg/week of testosterone cypionate. My natural total testosterone has tested around 280 ng/dL. I sleep well, train consistently, eat a good diet, and take my health seriously. I also have a family history of low testosterone levels. My main concern is HPG axis suppression. If I start 200mg/week at my age, is there a risk that my natural testosterone production could be permanently shut down, even if I stop later? How common is permanent suppression versus recovery after discontinuation? Also, given my age and baseline testosterone level, would you recommend further investigation into potential causes before starting TRT? Thanks.
