At Milestone, we started this company because we were tired of seeing researchers let down by companies cutting corners. We’re a small, family-run business that takes pride in doing things the right way—every batch we sell is third-party tested, and we refuse to compromise on quality or integrity.

We know it’s easy for others to make big claims, but for us, it’s personal. We built Milestone because we wanted researchers like you to have a source you can trust, with no gimmicks or empty promises. When you choose Milestone, you’re not just a customer—you’re part of a mission to raise the standards in this industry. We take that responsibility seriously, and we’re here to prove it every day.
