Choosing the right syringe
How to choose the right syringe is a very important question and you undoubtedly have to know the proper answer to it. First of all, you will need the syringe for the required amount. The liquid is measured in cubic millimeters. Secondly, you need a needle which will enter deep into the muscle for optimal absorption. Also it need to have a sufficient diameter to pass the oil, but not too wide, so as not to injure yourself.
There are many different types of syringes available, some longer, some thicker. Most bodybuilders prefer 2-3 ml syringes. The best advice here if you are not sure about how to select the syringe is to consult your pharmacist.
