Primo is one of my favorite compounds . when I'm not running a huge massing blast , i cruise on primo with my TRT . great all around compound, the cleanest, fewest sides compound I've ever ran . thats why i feel i can run it long term on/with my TRT .
of course in bodybuilding it has its place mainly as a contest prep drug , as its one of the most anti-catabolic compounds as regards to maintaining muscle while in a hypo- caloric diet.
whats your goal and purpose of wanting to run it ? mg per mg, its one of the priciest steroids out there
