Your body must convert it back to the reduced form before it can be used, which is an inefficient process
Vitamin B12 does have the potential to react with certain medications including chloramphenicol, proton pump inhibitors, H2 receptor antagonists, and Metformin
However, the body only uses and stores as much b12 as it needs and any excess is excreted in the urine
Sterile water does not contain benzyl alcohol and is typically for single-use only
Subcutaneous injection (most peptides) Best sites: Abdomen (2+ inches from navel) Thighs (outer) Love handles Back of arms (harder to reach) Technique: Clean injection site with alcohol Pinch skin to create fold Insert needle at 45-90 degree angle Inject slowly (2-3 seconds) Remove needle, apply pressure Intramuscular injection (some peptides) Best sites: Glutes (upper outer quadrant) Thighs (vastus lateralis) Deltoids (shoulders) Technique: Clean injection site Insert needle at 90 degrees (deeper than SubQ) Aspirate (pull back plunger slightly to check for blood) Inject slowly Remove and apply pressure Rotation and site management Rotate injection sites: Never use same spot twice in one week Have 8-10 sites in rotation Track sites if injecting multiple times daily Avoid: Injecting into scar tissue Sites with visible inflammation Areas with lumps from previous injections Learn complete technique in our peptide injections guide
FDA scientists remain unconvinced In recent years, the FDA has warned Americans about the risks of injecting peptides like BPC-157 and TB-500, another compound set for review
