For peptides that do not dissolve cleanly in bacteriostatic water alone typically those with hydrophobic sequences or basic amino acid-rich compositions that require protonation for solubilisation the recommended approach is to first perform initial reconstitution in a small volume of 0.1% acetic acid water (also available from Peptides Lab UK) to produce a clear stock solution, before diluting further with bacteriostatic water or the relevant physiological buffer
The question of which is "better" is rarely a simple one-to-one comparison
In addition, peptide nasal sprays are known for their ease of use and convenience, because they require no needles or injections
This is the traditional medical route
