Some of you may know that METHYLCOBALAMIN is the truly potent form of B-12 that is only well absorbed when delivered via injection. Lymies have reported substantial gains in overall health from regular injections of methyl and there are even reports of repair of neurological damage from taking it.
Finding compounding pharmas with Internet sites isn't easy, but I found one. Methyl isn't cheap, but it is far more potent about conventional B-12. The product is a kit that supplies everything you need, including tiny gauge insulin needles. It is delivered IM not intravenously. Just a little poke into the muscle.
