You don't need Halo for precontest unless you're powerlifting. You need to stop the gear 2 weeks out to allow for all water to drop from your body. Just because you're not using gear that aromatizes doesn't mean you don't hold some water. Also, I would add Proviron the last 6 weeks for the added benefit of hardening and libido. Other than that, it's not the gear but your diet and training that will dictate how you look. Good luck and post up your progress.
