Testocreme comes in a small container 30 grams at 10% per gram and each gram is a 1/4 tsp. I ask them to put the creme into 3 10 cc syringes to make it 30 grams and take 1/2 cc a day, because the creme makes a big mess and waste alot BUT on the side of the syringes it says that 1/4 tsp = 1.25 cc. WTF. So basically I am taking about 3.25 % per 1/2 cc and getting shafted no wonder i been feeling like crap and when I was taking at 1/4 tsp a day out of the jar I was growing like wild fire. So if I gett this at 15% this should solve the problem to get full dosage as required.
