Does my Ghk-Cu look cloudy?

Got it from JEEP. Reconstituted 50mg with 3ml of bac water. It’s been 3 days and looks opaque compared to the previous ghk cu I bought from Sigma Audley.

Is this good/beneficial to use? Or has it been degraded and wasted?
 
When you initially reconstituted it, was the solution clear, and did it later become cloudy after refrigeration?

I wouldn’t use it in its current cloudy state. GHK-Cu should remain clear, and cloudiness after refrigeration—especially at this concentration—likely indicates precipitation or instability. Since it doesn’t match how your previous Sigma-Aldrich GHK-Cu behaved, I’m erring on the side of safety and not using it.
GHK-Cu is sensitive to concentration, pH, and temperature. To prevent cloudiness/precipitation, it should be reconstituted more dilute (for example, 50 mg with 5–10 mL), mixed gently without shaking, and stored consistently in the refrigerator without freezing or large temperature swings. Using fresh BAC water, minimizing vial punctures, and allowing it to warm to room temperature before use also helps keep it stable.
 
Does it look clear in the vial? Or also opaque in the vial?

I haven't reconned GHK-Cu yet, but I have more than a couple of times had a little cloudiness in the syringe even though the vial was clear. Fine enough to me.

That reminds me of reconning HGH (very fragile compared to a GLP). If I forget to use a vent needle during recon, instant foaming due to the vacuum of the vial causing the BAC to mix too quick/hard.

You should take a pic of your vial, syringe isn't as transparent as glass.

Thoughts? Safe/good to use?

I don't know about cloudy or not, but the spots would bother me if it was my stuff. Air bubbles?

I dunno. Personally, I would dump it. I mean what does the stuff cost? Like $10 for a brand new vial? Maybe do a deep clean of your equipment, storage and prep area while you're at it.
 
Generally speaking (and for what it's worth), Gemini is not happy with opacity:

Despite its color, it should still be perfectly clear, allowing light to pass through without cloudiness, haziness, or floating particles.
But if you add a liter of BAC, anything would be clear enough.

The problem may the definition of clear. I uploaded your pics, and Gemini says the syringe and vial are both clear:

The reconstituted GHK-Cu solution appears to be clear and translucent, with the expected blue color.
 
i asked chatgpt, he said throw that shi out LOL, anyways just ordered bigger syringes 5ml for reconstitution with 30g to not splash all the water inside the peptide
And use a vent needle, like even a syringe needle would work for venting the vacuum. Otherwise, the BAC can come in very quick and hard.
 
Looks fine, though I would ideally use at least 1" for the needle length.

This place also sells name brand, Easy Touch, without the needle:


They also sell much cheaper generic syringes.

lol why u linked syringes without needle? did the one i linked's needles are not good?
 
I buy both kinds (with and without a needle), but the half-inch needle is a little short for the one you bought. Will still work though. Just won't be able to get needle to side of vial. 1.5" may be ideal.
