Hello, just a few quick questions regarding a few supplements. Ive looked around and i cannot find anything concrete about if you are able to use any of these in WADA/IOC tested sports
-Npept-10 (n-phenylacetyl-l-prolylglycine) :also detection time?
-DS ( along with a few other ingredients) :also detection time?
-Caffeine (regarding cutoff for legality; i believe there is a certain threshold you cannot pass)
thanks for the help
