Start with 1/2 a serving! Most of our customers start with a 1/2 serving (1/2 scoop) to determine tolerance. Make no mistake, STIMUL8 is not a 2, 3, or 4 scoop product! Due to the extreme effects formula, most men & women find that 1/2 serving is just right! When in doubt start with a 1/2 serving of STIMUL8 to assess tolerance, do not exceed recommended dosage.
