What is the difference between this and 1-test base? I know kilosports sells it but other than them i've never seen before?
1-test base is exactly that. 1- test without an ether or ester attached. 1-test thp is 1-test with a TetraHydroPyranyl ether attached. It greatly improves the oral bioavailabilty of the hormone. An example of this is Molecular 1-test ethergels.
Thanks for the info bro!
