Not really sure where to post this but I am sure this is where I will most likely get an answer
I have been using d-aspatric acid as a supplement on and off for around 6-months. I have test results from on and off the supplement which indicate it is c=increasing testosterone concentrations significantly - taking my free and total testosterone levels around 20% higher than the accepted upper range in the UK. I am wondering about the possibility of Leydig cell burn out from continual high level production and secretion of testosterone? I would appreciate members thoughts.
