Black Flag is a completely new sports nutrition brand although you might not think that looking at the formula behind its debut product and comprehensive pre-workout, Rattle. This thing is absolutely loaded, and we’re not saying that because its from a newcomer. Black Flag has completely stacked its Rattle pre-workout, bringing together a host of reliable ingredients for all of the core benefits from energy and focus to pumps and performance, and the dosages take things even further by not always sticking to the typical amount.
We’ve got the facts panel for Black Flag’s Rattle pre-workout directly below, tipping the scales at 22g per maximum serving, with a little under 20g of that actives. While it does have a wide variety of ingredients for all of the common effects, the formula definitely favors the stimulant side of things. For pumps and performance, there is 3.5g of beta-alanine, a gram each of agmatine and taurine, and the ever-present pump-powering citrulline, straight citrulline, at a huge 9g per serving.
Moving on to the rest of the fully transparent formula behind Black Flag’s first-ever supplement, Rattle, this is where that potent, intense, and undoubtedly hard-hitting stimulant side comes into play. Just purely for focus and concentration, the pre-workout packs 350mcg of huperzine, 600mg of alpha-GPC, half a gram of the nootropic mushroom lion’s mane, a solid 2.5g of tyrosine, 100mg of KannEase branded kanna or sceletium tortuosum, and for a bit of a thermogenic-enhancing sweat effect, there is 25mg of ProGBB.
The last few ingredients to highlight in Black Flag’s Rattle pre-workout are the energy components, and there is plenty in there to pack a punch. In combination with everything mentioned above, the newcomer has stacked the supplement with 400mg of eria jarensis and 2.5mg of yohimbine as well as 2mg of the always intense alpha yohimbine. Caffeine, of course, is a part of the experience, with Black Flag jamming a rarely seen half a gram in its maximum serving, from caffeine anhydrous, caffeine citrate, and Infinergy di-caffeine malate.
As mentioned earlier, despite Black Flag being new to the sports nutrition industry and Rattle being its first supplement out of the gate, the list of ingredients and dosages in Rattle does not reflect that. The brand has genuinely put together a premium and powerhouse formula for its foray into the industry, and we don’t foresee this not leaving an impression on pre-workout fans of any level. Black Flag Rattle is going live on its website shortly at $59.99 for a full-size tub of 20 maximum servings in the one Blackberry Lemonade flavor.
