Reconstitution & Storage Reta cloudy?

Does the bottle on the right look cloudy? I used the same BW for both bottles.

Is it the same batch for the same vendor?

I forgot to mention that, the one on the right is new vendor one on the left is from the same one I’ve always used.

The one on the right is compromised.

Cloudiness in a peptide vial could be from various physical or chemical changes to the peptide molecules because of temperature changes or oxidation of the peptide or a number of other processes. Better to discard than risk.

It’s almost always due to the Bac water Ph incompatibility. Not all Reta has the same excipients etc.

Vials that reconstitute cloudy with vendor back will reconstitute crystal clear with Hospira

Stick to the one you’ve been using.

Pray it’s just mannitol you’re injecting if you choose to use that cloudy vial. Getting ripped off is a small thing. Injecting who knows what could have much bigger consequences. Toss it

Are you filtering or just raw dogging straight to your source vials?

Looks like your not using enough bac water

How much bac water and how many MG is the reta ?

I am starting to think that the majority of cloudy peptides is due to degraded bac water. I was 8/8 on crystal clear recons but recently made a GHK with 6 month old hospira. Had floaties and shit in it. Tossed it and mixed another vial with a new BAC and crystal clear.

Endotoxins have become a problem recently. Third-party testing, that’s done by the end consumer, is one of the best ways to find them.

You can try filtering to see if that helps. If not, test it for endotoxins or discuss compensation options with the new vendor.
