haven't tried it but....
I have used products by their company before and i absolutley loved them. It is not actually oral test, It is what is called a testosterone mimetic. It's response with the brain is very similar to that of testosterone and it has very similar effects, muscle gain, libido, strength etc. While this may raise endo-test that is not the main way it is working in the body. Like i said not actually test but, If Primordial performance is putting this out i think it is definatley a worthy purchase as their products tend to work as advertised.
They claim 8-10 lb gain in 4 weeks and the phsiological benefits provided by 400-500 mg of test a week, and i believe them
I would not reccomend replacing a test inj as the base of a cycle with this though,
hope my answer is helpful
