The goal is to support metabolism, increase energy, and maintain healthy levels of essential vitamins, since B12 deficiency is a possible side effect of some weight loss medications
Many sensitive peptides (pure lyophilised BPC-157, DSIP with its N-terminal tryptophan, TB-500 with oxidisable methionine) measurably lose activity beyond 14 to 21 days in solution, even at 2-8C
Vitamin B12 injections are most clinically appropriate in cases of confirmed vitamin B12 deficiency, malabsorption syndromes including pernicious anaemia or post-gastric surgery, significant symptoms where rapid restoration of vitamin B12 levels is required, or failure of oral supplementation due to poor absorption
The riskbenefit assessment for wellness or anti-aging interventions may differ substantially from that applied to disease-specific therapeutic indications, given the differing clinical objectives and risk tolerances
