Did I mess up my peptide by shaking it?

Summary

Does shaking a freshly reconstituted GHK-CU vial ruin the peptide?

The original poster added bac water quickly and then shook the vial hard, then worried after reading that shaking damages peptides. Several replies say the product is probably fine because peptides are tougher than the gentle-handling guides suggest, and one person cites a video of violent shaking that showed no damage. Others note the high concentration may cause painful injections but do not address the shaking concern.

What this discussion establishes

Rapid addition of bac water and subsequent hard shaking occurred in the first reconstitution.
The resulting solution appeared clear and dark blue, matching other examples seen online.
Peptides are described as more resilient than reconstitution guides imply, even surviving rough handling in testing.
High concentration (50 mg/ml) is flagged as likely to produce painful shots and lumps.
The incident is called a common rookie error that does not ruin the vial.

Nothing here is advice.

I received my first batch of GHK-CU and added 2ML of bac water to the 100mg vial. When I inserted the needle all the water rushed in at an angle right away. I didn't expect it to empty that fast. After that I shook the vial gently at first and then harder. It came out clear and dark blue like the ones I've seen online and I put it in the fridge. I left the bac water at room temperature since I heard it doesn't need refrigeration. Then I read that shaking ruins peptides, so did I wreck the vial?

How fragile are peptides really? I've been reading up on them a lot lately and the guides always stress adding the solution carefully and mixing gently to avoid damage. Yet the same peptides get shipped through regular carriers that I know bounce them around plenty.

Welcome to peptide heaven. I think you're probably fine. You're just starting out. I would suggest watching some videos on proper reconstitution technique or searching the topic here and doing some reading. It's easy to mess things up if you don't know what you're doing.

Hopefully you've checked into the details already since this compound tends to produce injections that sting badly and often result in bumps or swellings under the skin. That issue stands out more when the mixture strength matches the one you're planning so the shot ends up quite uncomfortable.

Lots of newcomers around here ran into that issue when readying their starting container. So no reason to stress since everything turned out okay.
