So, I now have 30ml Bacteriostatic water. I just want to ensure I have the mixing instructions correct. I hate to ask a redundant question. It seems most everything has been answered on these forums at one point or another, but when it comes to mixing HcG, there are conflicting answers. Below is the best explained I found - is it still accurate, also I have questions in red:

Sterilize all vials.

You have a amp with powder, and vial of bac water, and an empty 10ml vial.
If unable to obtain 10ml vials, can we use 10ml syringes?

Draw 2ml bac water, pin into empty 10ml vial. Repeat that one more time. Now u have 4ml bac water in vial. Why do this twice and not just draw up 4ml the first time?

Break amp top, draw 1ml bac water. SLOWLY pin 1ml water to powder. Swirl in your hands. Draw up the mixture into syringe. with an amp you have to break, is it necessary to use a filtered needle? Also are you adding the 1ml to the amp you just broke or did the HCG get places elsewhere?

SLOWLY inject into vial with 4ml water. Again slowly swirl vial in your hands. You now have 5mls of back water, but when the HCG dissolves, does this add to the volume - adding cc's? I know with certain antibiotics you account for the powder as it will add to volume.

Now u have it mix. Draw .25ml in a slin pin. For 250ius. I've seen the math done many way's, I'm assuming this is for 5000iu HCG w/ 5mls (assuming the powder doesn't add volume) 1ml = 1000iu therefore .25ml = 250ius the required dose.
