💡 Why We Started


Hey there 👋 We’re Mark and Lisa — a husband and wife team from Texas with a shared love for science, small business, and giving back ❤️

We started Pure Peptide Labs in a quiet study room at our hometown library, driven by one big idea: to make it easier for researchers to access honest, high-purity peptides without overpriced markups or shady sourcing.

From day one, we’ve done everything ourselves — from testing and packaging to customer support and shipping. Every vial we send out is packed with care, because this isn’t just a business to us — it’s personal.

And just as important as quality is purpose. A portion of every sale goes to support the fight against childhood cancer, a cause that’s close to our hearts 💛


After seeing so many overpriced, under-tested, or sketchy peptide vendors flooding the market, we decided to start something better — something honest.

Pure Peptide Labs was created to bring real researchers like you:

  • Top-quality peptides tested via HPLC & Mass Spectrometry
  • >99% purity with Certificates of Analysis included
  • And no ridiculous markups or vague sourcing

We’re proud to be a U.S.-based small business, and we treat every order like it’s going to someone we know — because sometimes, it is.
