The point is that you CAN'T have cyano in your system! It won't do you any good, due to the MTHFR!

Any reaction would probably be a localized pinkness. I'd say redness, but that's not really accurate. I did fine on the shots, and had absolutely no reaction.

Take it one step at a time!

Amazon has Jarrow 5000 mcg. tabs and they're cheaper than from iherb. In general, I like to get my supplements at iherb, due to the return policy, free shipping, etc.

Whatever else you do, you might want to take things one thing at a time, so that you can know if you're having any side effects or not (not from the B12, but the other big drugs!).
