I would just follow dosing instructions. for MFX v3. you want to dose 2 upon waking and 2 later in the afternoon, you can use 2 caps 30 minutes pre workout for a boost but make sure that your doses are seperated by about 6 hours.
The same goes for Hard-FX, 2 upon waking and 2 later in the day. Mass FX can generally be taken with meals however Hard-FX will do best on an empty stomach.
For Lean FX, dose 1 upon waking, 1 4 hours later and then 1 in the early afternoon. The reason you dose upon waking is because cortisol levels are generally higher at this time because of the 5-8 hour fast(sleeping), then about 4 hours after waking up you get another spike in cortisol so thats another great time to dose it.
