hcg administering

[missionpossible]

On the hcg, I receive two amps, one product and one solvent I assume. So, do you just mix in the solvent and then draw it up into the syringes in the amounts that you want per dose and store the syringes then? How long can you keep these pre loaded syringes? I picked up some 29 x 1/2 for the hcg, are these OK?

Thanks guys!
