[QUOTE="Blackhawk, post: 237741, member: 16042"] You are not stupid, it is confusing. Your U-40 syringes are really made for a specific type of insulin measured in U-40 units, not testosterone, and the units do not correlate directly in the usual decimal system related to ml. (i.e. tenths hundredths etc). This is pretty screwed up for trying to figure dosing T. There are three variables in your situation: [B]Concentration: [/B]This is how much testosterone there is per ml in the vial you are provided. This is commonly either 100mg/ml, or 200mg/ml, or 250mg/ml. [B]Syringe Volume:[/B] a 1ml syringe holds up to 1 ml. a 0.5ml syringe holds up to 0.5ml fluid volume. a 0.3ml syringe holds up to 0.3ml, With smaller sizes, it is easier to see smaller dose increments when drawing up your dose. [B]Syringe Gradation:[/B] U-100: the lines on the syringe indicate hundredths of a ml. U-40: the lines indicate 40ths of an ml. In effect the U-100 is a more accurate system of measurement. So, you are also confusing the syringe volume with the gradation. An insulin syringe is typically 1ml, 0.5ml or 0.3ml in volume and any of those sizes can be graded with U-40 or U-100 units. In your ciphering above, the 0.5 ml syringe size is irrelevant in calculating how many units for your dose. It only designates how much the syringe will hold. Here's an example based on your 15mg dose size and 250mg/ml concentration: With 250mg/ml testosterone, the volume is 0.06ml for 15mg. With the already calculated U-40 syringe: 15mg is 0.06ml which is 2.4 units. 2.4 is between the 2nd and 3rd lines on the syringe whether it is a 0.3, 0.5 or 1ml syringe size... what matters is the U-40 unit volume. With a U-100 syringe, 15mg is 0.06 ml which is 6 U-100 units. this is 6 units on any U-100 syringe, 0.3 or 0.5 or 1ml syringe size. Personally i would choose a U-100 0.3ml insulin syringe for this dose. It is easier to see the gradations on the syringe for such a small 6 unit dose. [/QUOTE]
