i ordered 6x500mg vials but They sent me a box with 3x500mg and 1x1000 mg and two index cards. No instructions or needles to use. The stuff in the vials is solid. There is no possible way to inject solid material into your body. I feel scammed. They wont return my text or my emails. Im so mad!!

Hi Cathy, You're right to be frustrated — a partial box with no explanation isn't the experience we want anyone to have. Here's what happened: your order shipped in two packages. The remaining vials are in transit with USPS right now and are on their way. We emailed you the tracking and replied to your text as well — please check your spam/junk folders if you did not receive these. On the vials themselves: research peptides ship as a lyophilized powder. That's not a defect — it's how every research laboratory ships them, because the powder form is what keeps the compound stable in transit. We're a research peptide company, so we don't include needles or dosing instructions with orders, as per FDA regulations. I'd like to make this right. I'm sending your tracking again now, and I'll personally follow up until every vial is in your hands. Reply to this or text us and I'll take care of it directly. — Emily, Product Manager

I had a problem with my first delivery being lost and Prism Labs gave me no issues and took it upon themselves to resend order. Super happy with items and quality. Received my order they resent today, beyond happy with company.

I place an order of the GLP-3 RETA 30mg i purchase three vials and only received one I called a few times and emailed and still no response! I appreciate the same day response! I appreciate also taking accountability that my package was missing the other two vials. I’m glad that they will be sending me the two vials! I always believe in second chances

Magaly — thank you, we really appreciate that. Your two vials are on the way, and the tracking will show up in your account. If anything else comes up, email me directly and I'll take care of it personally. Thanks for giving us the chance to make it right. — Jake, Prism Labs Support
