I hear a lot of peolple on this forum telling others not to hit any juice till they have completed at least 3-4 years of hard training and sometimes even more.Ive also heard people say that they think that bodybuilders that started juice later then others also end up bigger (not because of stunted growth -assume both had finished growing). And that unless you have reached your genetic potential that juice will not be able to bring you to the same level as someone that has waited? I was wondering why this is? If you manage to complete an effective pct and your levels all return to normal (after the expected decrease in strength and size), and you continue to train, shouldnt future gains in strength and size return to what they were previous to the cycle? or does juicing put u at a permanent disadvantage for the rest of your life unless you cycle again?
