pH Compatibility Analysis Reveals a Shared Stability Window Comparing the optimal pH ranges for each peptide and the reconstitution vehicle: Copper tripeptide (GHK-Cu): 5.07.0 (optimal 5.57.0) Thymosin fragment (TB-500): 4.57.5 (optimal 6.07.5) Body protection compound (BPC-157): 6.58.5 (stable across wider range, including more acidic conditions) Bacteriostatic water: pH 5.7 (range 4.57.0) The overlapping stability region spans approximately pH 5.57.0 , with the bacteriostatic waters pH of 5.7 falling near the optimal range for the copper tripeptide and within acceptable ranges for all three peptides

We therefore agree with the Statement of the International Society for Nutritional Psychiatry Research (ISNPR), which, at a scientific meeting that brought together high-level experts convened specifically to reach a conclusion on the use of these substances in the treatment of depression, concluded that oral omega-3 supplementation may be recommended as an additional treatment in adults diagnosed with major depression [120]

Some do a short loading phase, then move to maintenance
