Twice a year I get my bloods done the week of seeing my Endo.
I run blast and cruises twice a year. Generally 16 week blasts. Then I go back down to my 200 mg a week dosage and run that for 3 months.
Everything is bang on. I didn't get psa checked because of a form error but it's always 0.1. Normal. Vit D is getting checked again as I have some hx of low numbers, but that may not translate to anything clinically.
Moral of the story..always do bloods. At least once a year. Live a positive lifestyle, even when using super supps. It pays for itself!!
