General principles of aseptic reconstitution for lyophilised peptides include: Gather equipment: Bacteriostatic water (if available and appropriate), the peptide vial, appropriate syringes, alcohol swabs, and clean gloves
Laboratory and/or medical tests (e.g., serum potassium levels, complete blood count, hematocrit, vitamin B-12 levels) should be performed to monitor your progress or check for side effects

It's very clear that a lot of them are contaminated with things that both in the short term, but especially in the long term can be problematic
In white adipose tissue of obese, insulin-resistant and aged mammals, NNMT is dramatically upregulated and because it consumes both the universal methyl donor (SAM) and the NAD precursor (nicotinamide), its hyperactivity simultaneously depletes the cellular methylation reserve and the NAD-salvage pool [1,2]
