While Performix did say that they weren’t officially going to reveal anything until yesterday, we did manage to get the jump on their latest supplement over the weekend. The name of the product is Stimfree, a stimulant free thermogenic solution that as we mentioned previously, is rather impressive having nothing in common with either of the brand’s other fat burners. Not only is Performix’s fifth formula perfectly stackable with the SSTs, but it is also now available. The brand did basically confirm what we already knew yesterday, and today have launched Stimfree through GNC. If you are new to Performix as well as GNC, you probably won’t mind giving them a go with it’s price at $79.99, $20 less than the regular cost of SST powder or pills. Alternatively if you are a Performix fan and Gold Card member, you won’t unfortunately save anywhere near as much compared to the brand’s other weight loss formulas. The stimulant free supplement only drops $20 to $59.99, making it the same price as the capsule SST, and $10 more than the iceberry flavored powder.
