Hi.
As you know there are some concerns about link between sarcosine and prostate cancer. It is unknown whether sarcosine is cancer trigger or oncometabolite or co-carcinogen. But if you do google search with “sarcosine cancer” there will be some frightening studies. I think it would be useful to do a PSA test if you are using sarcosine as supplement.
Has anyone done the PSA test?
