how come nobody runs T400 or T250...or at least talk bout it on here? both awsome test. especially the 400... more bang for the buck. lot less water retention than E alone, fast acting cuz of the prop. but dont have to inject as often cuz of the E and Cyp. i kno the old gear was so painful cuz of the high BA content due to such a high consentration of test per ml but the new stuff is smooth man...i have even taken 2cc of Vet. grade in my traps, and lats. it is the only test i will run any more, unless i can get some home brew E just cuz of price.
