Absolutely Primobolan - methenolone - without a doubt. This is why you hear of more people, including myself that use it rather than test for contest preparation. Primobolan - methenolone - is actually my drug of choice over anything else, with the exception of human growth hormone - somatropin - . I just get better gains from it with virtually no sides at all. The gains last practically forever as well. If using test, once you come off of it you piss alot of your size away since a vast majority of them are from water retention. Hope this answers your questions.
