That is the broscience consensus, but it's not as bulletproof as people like to believe. It will probably work for a 25 year old after 1-2 months of dabbling, but the TRT forums are full of stories where these tricks don’t work or stop working after extended use.
The tricks are not guaranteed like some of the forums or sketchy TRT clinics will claim. Atrophy can be permanent after relatively moderate periods, even with all of the HCG and SERM tricks.
