i am going to be starting my 3rd cycle very soon but my contact can only get test 400 has anybody used this or know much about it?

previous cycles were test cyp (testex) for 12 weeks 2nd cycle was 12 weeks of test enath (testoviron ) i had great results from the testex but not so good from the testoviron. also the testoviron was pianful to inject.

any info on test 400 would be great

thanks in advance
