It certainly could, but the same thing can happen at any age. There are plenty of young dudes who ran one cycle and never fully recovered. Even with a proper PCT some guys just don’t properly recover. There are also plenty of guys who cycled for many years and have no recovery issues, relatively speaking. Personally, the thing I’ve noticed with age is how hard some compounds are on my body. Things I used when I was younger kick my ass now, not all of them, but some. You really have to weigh the pros and cons before starting and if you decide to run something, be prepared for a lifetime of TRT. Maybe you’ll be fine, maybe not, just know that you may be one of the unfortunate guys who doesn’t recover well. On a side note, HCG should not be part of PCT. I’ve never used HCG so I’ll let someone with experience explain why and provide some guidance.
