Stimulin Amino Compound Based on liver extract with the crucial amino acids dissolved into it, Stimulin is a must for me in or on just about every bait I use. Apart from being a serious feeding trigger, Stimulin also acts as a short-term preservative. By that I don’t mean shelf life type preservative but one that can be added to fresh baits. Just add a little to the bait bag and shake. A thin coating of Stimulin will give a few days extra life to bait taken on summer sessions where freshness can be a worrying factor.I recommend 10–15 ml per 6-egg mix. ‘Stim’ is available in 100 ml and 500 ml bottles.
