¡Excelente experiencia con Poly Biotech! Compré Glow70 y llegó rapidísimo, bien empacado y con excelente atención por WhatsApp. El producto es de muy buena calidad y el precio es el mejor que he encontrado en Colombia. Sin duda volveré a comprar.

Shipping was fast, very helpful team. Will be back

the order arrived fast and well packed, and the team kept me updated. You can tell they really care about their customers.

This was my first time ordering from Poly Biotech, and I’m genuinely impressed with the overall experience. Before placing the order, I reached out via WhatsApp to confirm a few details - response time was quick, clear, and professional. That gave me a lot more confidence compared to other sites I’ve used in the past.

The order was processed immediately and shipped out the same day. It arrived clearly labeled and well presented. The product quality looks excellent - no issues with the vial, and the labeling matches exactly what’s shown on the site.

What really stood out was that they included a few small extras in the package - nothing I asked for, just a nice touch from their team. When I messaged to thank them, they said it was a gift for first-time customers. That level of detail and care is rare.

Solid service, transparent communication, and fast fulfillment - hard to ask for more.
