You should have received some BW with your vial. The vial holds 8CCs of BW, and contains 1 gram of powder. It must be a dense substance because it doesn't look like much sitting at the bottom of the vial.
I've been taking 2 50mcg injections (one morning...other at night) every day. My first vial I reconstituted with 8CCs so my injections were 40 units each. However IBE recommends using 1 to 2CCs for reconstitution. I tried 2CCs on my second vial and was a little disappointed. 10 unit injections seem too small. I think I will use at least 4CCs maybe 8 on my next batch.
When did you hear the product would be replaced?
