The thread shows one user considering splitting a 100mg reconstitution into multiple pen cartridges for freezing to avoid long-term fridge storage. Others advise simply dosing daily from the fridge with good hygiene to limit degradation. Personal risk tolerance varies around using older BAC water for slow-consumption vials, and some recall GHK-Cu breaking down faster than other peptides, especially in light.
What this discussion establishesVarying personal thresholds for how old BAC or reconstituted vials are acceptable before switching to fresh ones.
Still openWhether GHK-Cu specifically degrades into any harmful compounds or exact stability timelines after reconstitution.
Nothing here is advice.
With 100mg vials of ghk-cu, how do you finish them before they go bad? At 1-2 mg a day that's over 50 days. Does the reconstituted version freeze okay? Could I mix the 100mg and split it into three pen cartridges, freezing two for future?
I'd simply use 2mg every day from the cartridges until they're gone. As long as sterility is maintained, there shouldn't be much breakdown in the BAC or the GHK-Cu.
Perhaps just storing the cartridges at the back of the refrigerator would work.
A 50+ day vial doesn't concern me much, and I keep good hygiene with my vials. (Not claiming full sterile techniques since no hood is involved, but careful enough.) For an older vial that's already 60+ days, I'd open a fresh one instead of reconstituting a peptide meant for long-term use. BAC can be used up to 90+ days, but not for mixing something that lasts another 50. Still okay for quick-use vials. Risk tolerance varies, so this is just my approach.
Is it correct that ghk-cu breaks down somewhat quicker compared to other peptides?
I think I've seen that mentioned too and will need to look it up. Since this is more of a cosmetic and repair peptide for joints or skin, I don't stress over degradation the way I would with a GLP. If it loses potency I simply won't get the same appearance benefits, right? 😂 Still, if reports show these compounds turning into harmful byproducts, let me know so I can adjust how I handle them.
True, particularly when exposed to light.
