MK.IV - October 2018. Increased caffeine to 200mg to provide a more tangible energy boost. Added Panax Ginseng based on literature around cognitive boost and mood effect. Removed vinpocetine, L-tyrosine and B Vitamins to simplify, based on results of clinical trial.
MK.III - Upgraded formulation. Deprecated glucuronolactone and inositol. Added vinpocetine and L-tyrosine to focus on reaction time and performance endurance. Potential synergies for these compounds on the current Caffeine + L-Theanine stack was studied in a clinical trial.
MK.II - We reduced the amount of Vitamin B6 and B12 so it's possible to use SPRINT on a daily basis.
MK.I - Launched March 2015 via Indiegogo.
