I liked Post CT but I don?t know if it?s around anymore. Enhanced athlete Black Ox has the most compounds at clinical trial doses I have seen. I am currently on it now during my PCT. I like to suggest running individual ingredients which you can buy off amazon. A lot of the times you can buy the ingredients individually and run them at clinical doses for cheaper then buying an all in one test booster.
Ashwagandga
Tribulis
Long jack
Akarakara
Taurine
D-aspartic acid(run for 4 weeks at a time)
These are some of my staple test boosting ingredients that I incorporate into my everyday and PCT.
