Try 1000-2000 mcg's of B12 when you get up for energy. 4000i.u's of Vitamin D. Forget about lab resuts go by how you feel. My b12 level was maxed on paper taking 500mcg's. D takes a while to build up, also takes a long time to go down. It get's absorbed in your cells & doesn't just pee out.
Some body builders inject B12. No idea what dose that would =.
I take 7 baclofen/day for spasms.
