Peptide compatibility reports for nasal sprays and saline buffers

I bought a case of the BAC NaCl because several items on the list are cheaper that way. One of my MOTS-C vials thickened in the fridge but returned to normal once warmed to room temperature. The air bubble moves slowly when cold but the solution stays clear. I have been using it on the scheduled days with no problems during injection.

Has anyone tried Cartalax or the 5A1Q compound with BAC sodium chloride?

I mixed a vial that had already been compromised using 3 mL of saline BAC. It showed bubbles and a thick gel-like appearance at first but cleared within about twenty minutes. The same kit mixed with regular BAC went perfectly with no gel phase. I would only feel comfortable trying this at lower concentrations and would not rely on any PBS buffer sold for injection use.

Does the sodium chloride interfere with the copper ions in GHK-CU?

A mouse study on intranasal use used plain saline without apparent immediate issues, though longer-term effects on the compound remain unknown. I have added GHK-Cu to a KPV syringe that was reconstituted with BAC saline.

The list is useful but anecdotal results should be treated cautiously because formulation differences can change outcomes. One name that came up still needs proper testing data before assuming compatibility.

After mixing NAD with BAC NaCl the solution feels thicker and harder to draw, though it stays clear and injects fine. Adding a small amount of sodium bicarb helped reduce the sting over time. Next time I may try a 50/50 mix with PBS to improve viscosity and possibly reduce the bicarb needed. I expect to freeze portions of the PBS since it comes in larger bottles.
