This source has hCG injectable liquid (already reconstituted), and freeze-dried hCG powder. Do you guys generally recommend buying in liquid or powder form? Do you have any specific protocol for reconstitution of the powder (bac. water ratio to hCG IU, etc.)?

Get the powder if this is being shipped to you. Once reconstituted to liquid form, HCG must be kept refrigerated or it goes off quickly. (I am doubtful of the claims that that particular brand is stable at room temperature, given that it is the same molecule.) With shipping from the usual sources (normally countries in the tropics), there is in any case a large risk of exposure to high (much more than room-) temperatures along the way.
Even having the powder shipped makes me nervous, although I do that myself due to high cost in the U.S.
You can reconstitute with less water, but a good rule of thumb is to add 1 ml bac water for each 1,000 IU HCG in the vial. Then your dose of 500 IU HCG would be 50 units on an insulin syringe.
