I just bought a 10,000 IU bottle of HCG with solvent for my PCT along with Clomid. Is there a proper protocol in combining the solvent with the powder (since I won't be using the whole bottle for my PCT) or do I just inject the solvent into the bottle of powder. Also, once I combine the solvent with the powder, does the same expiration date on the bottle still apply, or is there a certain amount of time it has to be used by?
