Vit b 12 injectable. Mine was very low. I am 6 needles into the 9 needle course. Kinda feel like I need one now but I am not due for another 3 weeks.
Instant results for something and long term results for others.
Instant eye sight improvement and colour change. Brain fog lifts. Energy levels slight after 1 but great after 3. Pins and needle about the third shot.
But all that depends on how low you were.
Certainly is a life changer.
