BGC has the best physical conditions in the metro for handling this compound, which is worth using properly. New building stock, reliable power, decent fridges, and units that are not sharing a compressor with four other households.
The workflow is straightforward. A 10mg vial takes 2mL of bacteriostatic water, which gives 5mg per millilitre. On a U-100 insulin syringe a 5mg dose is 50 units. That is two doses out of the vial. Subcutaneous, three to five times weekly in the commonly cited research protocol. The reconstituted vial lives at 2 to 8 degrees, travels in an insulated pouch, and gets discarded at fourteen days.
The fourteen-day limit almost never bites, which surprises people. Two doses per vial means you finish it inside a week whatever frequency you run. The limit that actually matters in BGC is the one on your wallet, and the metro hub works that number through in full.
Keep unopened vials dry, sealed and out of the door shelf. Dry is the stable state and there is no reason to reconstitute more than one vial ahead.
