is it a slin syringe?(1ml)
If so you should have 100 ticks. Puting in 5ml of BW would leave you at 100mcg per 5 ticks.
Also, i wouldnt freeze them, thats just me though. I dont like the idea of freezing and unfreezing because i think damage can be done in the thawing process. Others will say freeze. Fridge should be enough to keep them ok for a day or 2 no problem. I also would pre-load and freeze.
I say fridge it, pull it out when you need to dose.
