I noticed that some clinics have started to offer so-called p-shots, which is platelet-rich plasma (PRP), what is the opinion on this? And then there are t-shots, and it is claimed that even if a blood test shows that there is no shortage of testesterone, usually the blood tests are so narrow that they will not show a deficiency of testesterone even if a man could benefit from a t-shot. It sounds however rather dubious to me.
