Why is my vial cloudy, or the powder loose?
2 min read
In short: A vial that's cloudy straight after mixing may just need more time to dissolve. If it stays cloudy, has flecks or strands, or changes colour, don't use it. Powder that has broken into loose bits in transit is common, but powder that looks wet, shrunken or discoloured may have been damaged.
Cloudy after mixing
Common reasons:
- Not fully dissolved yet. Give it a few minutes in the fridge and swirl again.
- It was shaken and is foamy. Let the bubbles settle.
- The wrong liquid was used.
- The peptide has degraded or been contaminated.
If it's still cloudy after it has had time to dissolve, or you see flecks, strands, sediment or a colour change, don't use it. Ask your pharmacist or the product's supplier.
Loose powder instead of a solid "cake"
Freeze-dried peptides often look like a small solid disc, but the disc can break up into loose powder when knocked around in transit. On its own, that isn't a sign of a problem.
Be more cautious if the powder looks wet, has shrunk into a sticky film or droplets, has changed colour, or the seal is damaged. These can mean moisture or heat got in.
Very little powder visible
Small amounts of peptide can look like almost nothing at the bottom of a vial. Check the label for the amount, and look for a film on the glass.
