@picante, I'm not sure what's going on here. * I'm 99 percent certain that the methyl oil used to be deep blood red, just like the ad/me oil. That's why I asked for confirmation from other people who had ordered the methyl previously. Maybe I'm hallucinating. * Greg does say the methyl is supposed to be pink, which confuses me. Methylcobalamin is red. All the other b12 liquids I have ever used (injected, drops, sprays) are deep red. And most of those are about 1mg/ml, whereas the methyl oil is 3mg/ml. Why would it be a fairly pale pink?? It makes sense that the ad/me oil (10 mg/ml of ad & me) is darker than the methyl, but... * I haven't felt right since my last (I think red) methyl ran out. Don't know if it's something with the pink methyl, or something else. If my 3/day ad/me test works better, that will make me wonder if somehow my previous methyl was mislabeled ad/me. That seems really unlikely but I don't know how else to explain it.
