Why Peptide Prices Vary So Much (and Why Cheapest Is a Warning)
Short answer: Price gaps between vendors usually reflect testing, sourcing, and shipping — not a deal. The cheapest vial is often the untested one.
What you're actually paying for
Independent testing costs money. Domestic, reliable shipping costs money. A vendor that does neither can always undercut one that does.
Why cheapest is a warning
When a price is far below everyone else, ask what got cut to get there. Usually it's the part you can't see on arrival — the testing.
How to value-compare
Compare price against verifiable testing, not against price alone. Buying tested product once beats buying cheap product twice.
