i havent heard of it man , but if u want o run a cycle , test only first cycle , u want to learn how your body responds to test first as test should ALWAYS be the base to all cycles . when u use any steroids , they shutdown or slighly surpress your own production of it , so to compensate for having low or NO test in your body ... u need to take it to prevent sides of no test . learn how u repoond and recover to test alone . test p isnt the best choice either because its a short ester and needs to be injectied every other day . if u are new to injecting and proper technique ... thats not the best idea . run test like test e where u inject only twice a week for 12 weeks and learn proper technique and body reponses etc . be safe ... do it right . tren on its own will give u tren limp dick from having no test in your body .
