Since you are asking for a personal recommendation you might want to elaborate on yourself, experience, stats, goal for cycle and maybe what other compounds you are considering running with it. Luki's answer may still be the same but without much to go off on this board he's likely going to assume you are well above genetic limit, looking to put on size, and given question use it as a main driver in cycle likely paired with equal test and little else. If that's the case, you've got the answer (mine too - you need more primo) but if it's not might be worth adding some context unless he already knows you well.
