just break the capsule dilute the powder in water shake it well and use a syringe the squirt it in ur mouth just squirt half of it and keep the rest in the fridge, it won't stay long in there anyway u'll take the rest in a couple of days so no prob. with contamination.
for example try to dilute one capsule with 5ml water , which means a full 5ml syringe and squirt 2.5ml in ur mouth and store the rest 2.5ml
