From what I am told thats the longest anyone has tasted it, as for myself I have only tasted it once, like a funny acidic taste almost garlicy, went away after 20 min. If you hit a vein or pass through one thats the most likely cause. With higher potency tren,like 200mgs/ml thats when you get extremely strong and lean, but the added aggression is the only downside, my temperment is low and I hate driving in rush hour on it! LOL
