It was around 2 p.m. Pacific when I ordered a very large quantity from researchtianeptine.com for overnight shipping as my first order. Their prices are among the lowest I've seen for sodium, then started wondering if there was a reason for that and got a little nervous after I paid for it via Zelle because I had never ordered from these guys before. But sure enough, about an hour after I paid for my order I received a confirmation email with tracking. I paid $25 for overnight shipping and received my order less than 24 hours from when I placed it (around 11 a.m. the following day). Their sodium is top notch quality and very potent. The delivery time was clutch and I like in a vendor that does same day shipping so Ima keep buying from these guys for now as long as their prices remain the same. Overall good experience, nothing to complain about.
