GHK-cu came with water marks and refuses to fully dissolve

Hey everyone,

I'm hoping someone can help me out. I'd read about this happening to other people and followed what was suggested online. I pulled all the liquid into a 3ml syringe and pushed it back into the vial. That appeared to fix it, and the vial looked clear, but by the following day chunks had formed again.

I mixed up another vial to check whether it was just a fluke. I carried that vial in my pocket while doing chores for an hour, and eventually every chunk dissolved. Yet after a single day in the fridge, a spot of undissolved haze showed up once more.

Has this whole batch gone bad?

Before reconstitution, the vials appear acceptable, though they have a cloudy look. My guess is that the haze on the glass comes from the vials having been frozen and then relocated somewhere with more humidity.

In the photo, the mixed vial really doesn't look too bad. The cloudiness on the glass makes it difficult to judge. Are these 50mg vials? Was Hospira bac used? When an undissolved mist shows up out of nowhere, that's typically gelling triggered by a pH issue — have you tested the PH?

One thing to try: transfer it into a bigger vial, add another 3mL of bac, and observe what happens.

Now it’s clear to me that these vials hold 100mg each. With just 3 ml, the solution could end up overly concentrated. Adding 3 ml more of BAC to dilute it is certainly worth trying.

So to do that, I’d have to get sterile vials to move it into?

I strongly endorse this. You can find them in lots of different spots. Just be certain that what you are buying is genuinely sterile. I have stopped sharing links publicly. If you want a reliable supplier, send me a DM.

I've now split my GHK Cu (50) across 2 pen cartridges. This way it's less concentrated, which simplifies multipin use and lowers the chance of reactions.
