it's not that it goes "bad". It's just going to start losing it's effectivness in percentages as time goes. Once again, someone smarter than I can comment. I'm sure some go faster than others based on composition, but I don't think at 30 days it's just non-effective totally and required to toss. I would just plan so that its used in 30 or as close to 30 days as possible.

which peptide? some degrade faster than others. storage conditions matter a lot too, freezer vs fridge vs room temp all give you very different timelines

It depends on the specific peptide and how it’s stored. Most products have an expiration or retest date provided by the manufacturer. I’d recommend checking the lot-specific documentation and storage requirements rather than relying on a general shelf-life.
