My father is an internal medicine specialist (a medical doctor)
As you can guess he is extremely against using any kind of exogenous testosterone
I am explaining him that there are so many scientific background for PCT but he wants to see pubmed or such published articles
I have found this one yesterday
Recovery of spermatogenesis following testosterone replacement therapy or anabolic-androgenic steroid use
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4854084/
Could you also reply the ones you have found about Nolvadex, HCG usage for PCT
Thank you
