Restart is when you attempt to bring back your own natural production of testosterone after a cycle of steroids, or coming off TRT There's great information on this in the stickies – by KSman - and I am following a modified form of that protocol. I have a log running as well – and will be posting new blood soon after doing three weeks of hCG and a month of Clomid.
By the way – your information intrigue me immensely – as I had almost the exact same numbers as you as I mentioned (E.g. Total test 425 - then a year later posted 660 ng/dl). For a 49-year-old, at the time – a score over 600 would be considered relatively stellar – and you had similar numbers in your 50s. So, I'm just curious as to why you were Dr. recommended TRT. For me, I had to rely on an old college buddy, who is also my cardiologist – that saw a lot of benefits from people on the therapy in terms of improving lipid profile, and reducing cardiovascular risk – which it did for me. However, I was still not 100% convinced that I should start a life long program taking these meds - so I did the restart protocol – and just want to see where I end up naturally. However – I felt a lot better taking the Testosterone – so I may have to wind up going back on
