How to Measure Liquidex
Liquidex, the liquid sort of "generic" version of Arimidex, is a very concentrated substance, with 4 mg/ml being its rated concentration.
Arimidex is very potent (and not cheap either) and in many cases a person only needs to do like 1/4 mg of it for it to be effective.
But at that concentration,
1/4 mg of Arimidex,
in Liquidex at 4 mg/ml, means that ,
you would need to adminster 1/16 of a ml (cc)!
How the hell do you measure that?
Well, here is what I did.
The formulation of a "drop" of a liquid is actually a fairly controlled and repeatable process. Meaning, if all factors (liquid viscosity, temperature, pressure, etc.) are the same, the amount of liquid in each drop is fairly constant (if the drop is formed around a constant source .... like .... the head of a hollow needle .....).
So, I took a syringe, and sucked up like 3 CCs+ into it.
With an 18 gauge needle on the syringe, I carefully, slowly, pushed down the plunger, ....... and counted each drop ....
And after several trials, with very low amount of "drift" or changes in data, it turns out that ...
Liquidex, through an 18 gauge needle, at room temp, with the needle held stright down, will create 50 drops per ml.
So, extraploating from that (with a slight amount of "rounding" error),
When using Liquidex, take an 18 gauge needle and with the liquid at room temp, and with the needle held straight down,
for 1 mg Arimidex, 1/4 ml of Liquidex, measure 12 drops.
for 1/2 mg of Arimidex, 1/8 ml of Liquidex, measure 6 drops.
for 1/4 mg of Arimidex, 1/16 ml of Liquidex, measure 3 drops.
Hope this helps some people out there.
And for those that were thinking "did this guy WASTE all of that Liquidex?" - not a chance. I "dropped" it into the back end of another syringe, and then placed it back into the vial.
