Stimfree is yet another product from Performix that has a nice ingredient profile, but seems to fall short in terms of doses and cost-effectiveness.
Many of the ingredients in the formula look great for reducing appetite and improving fat-loss, however even at three capsules daily it seems unlikely that they’re effective doses.
Although this is a lower-cost supplement than many others from Performix, it’s still on the more-expensive end of the spectrum compared to other fat-burning supplements.
