A single misread number, like entering 1mL of water when you actually added 2mL, halves your concentration estimate and causes you to draw twice the intended dose
In the case of ampoules of B12 they are extremely unlikely to deteriorate unless stored in the light or above 25 degrees celsius
Additionally, Pernicious anemia, an autoimmune condition affecting the stomachs ability to produce intrinsic factor (a protein necessary for B12 absorption), can also lead to deficiency
Most of the evidence for BPC-157 and TB-500 in tendon and muscle healing comes from animal studies, not large human trials, so I treat them as a supportive tool rather than a guarantee
