Who sells this, and how you can check it

Everything on this page can be verified from the site itself. Nothing here is a claim you have to take on faith — and that is the whole point.

The seller / El vendedor

BioPeppers is the trade name of Arrieta Uniforms LLC, a company registered in Florida, United States. It is the entity that issues your receipt and the one that appears on your card statement as “ARRIETA* BIOPEPPERS”.

What we sell / Qué vendemos

Research-grade peptides, sold as laboratory materials. Not for human or animal consumption, not for diagnostic or therapeutic use, and not food, cosmetic or medicine.

We do not publish protocols, doses or expected outcomes, and we never will. If you are looking for that, we are not the right supplier — and any supplier that offers it is telling you something about how they operate.

Péptidos de grado investigación, vendidos como material de laboratorio. No publicamos protocolos, dosis ni resultados esperados.

How purity is proven / Cómo se prueba la pureza

Every batch carries a certificate of analysis issued by MEDUTEST · Maison d'Analyse · Genève, an independent laboratory. We do not issue our own COA, and we do not transcribe a number without the report behind it.

There are 5 laboratory certificates published right now, each with its report number, batch and date — and each one verifiable against the laboratory, not against us.

What ships / Qué llega

Discreet packaging with tracking, anywhere in Mexico. Every vial ships with 5 ml of bacteriostatic water included at no cost — you should not have to buy the solvent separately to use what you already paid for.

Empaque discreto con guía de rastreo, a todo México. Cada vial incluye 5 ml de agua bacteriostática sin costo.

What we guarantee / Qué garantizamos

Identity and purity against the COA. If what arrives does not correspond to the certificate of its batch, we replace it or refund it.

We do not offer "30 days, no questions asked" on opened vials, and we would rather say so than promise it: an opened vial of research material cannot go back into inventory, and a guarantee nobody can honour is worth less than no guarantee at all.

Garantía de identidad y pureza contra el COA. No ofrecemos devolución de vial abierto, y preferimos decirlo a prometerlo.
