Written by the company

Mile High Compounds is a family-owned and operated U.S. supplier of premium research compounds. Every lot is independently tested by ISO 17025 accredited labs — eight tests minimum, covering identity, purity, net content, USP <71> sterility, endotoxins, variance, and heavy metals. New lots run a 15-point panel that adds residual solvents, residual TFA, container closure integrity, water solubility, and a fentanyl screen. Every COA is published, not available on request. Order by 3 PM MST, Monday through Friday or before 12PM Saturday, and it ships the same day via FedEx 2 Day.

The Mile High Compounds Difference

Written by the company

1. Product
Mile High Compounds is different in three ways. Our peptides are sourced from U.S.-based, cGMP-certified manufacturers. Nothing arrives from an unverified supplier. Every lot is independently tested by ISO 17025 accredited laboratories before it is released. Eight tests are the floor: identity, purity, net content, 14-day sterility, endotoxins, conformity, and heavy metals — screened for lead, arsenic, mercury, and cadmium. New lots run our full 15-point panel, which adds residual solvents, residual trifluoroacetic acid (TFA), container closure integrity, water solubility, and a fentanyl screen. Every certificate of analysis is published publicly via our COA library. We are proud to be one of the most rigorously tested suppliers in the industry, more than any other we are aware of.
2. Service & Support
We ship six days a week from our warehouse in Scottsdale, Arizona. Place an order by 3 PM MST, Monday - Friday & 12 PM Saturday, and it goes out the same day. Orders over $300 ship free via FedEx 2 Day. We accept all major cards and back unopened product with a 14-day return policy. Support runs through email at support@milehighcompounds.is. Questions about a compound, a COA, or an order reach our team directly, and we answer quickly. Now over a year ago, this company was one person — customer service, fulfillment, logistics, packing every box. Today we are family owned and operated, based in Colorado Springs, Colorado. Our founder employs his parents and most of his extended family, people with real backgrounds in laboratory and medical work, operations, logistics, and service. We are obsessed about the little details and make sure your experience is exceptional.
3. Industry discounts
We offer discounts to veterans, active military, first responders, and public safety and service members. These are the people who spend their careers on the hard end of other people's worst days. Extending them better access to quality research materials is the least we can do. Verified through VerifyPass.

Top Tier Company

Max and his team are incredible, top tier! They do what they say, from testing to support. Everything is current and up to date, and we all know how important that is. Transparency is something they own. They go the extra mile so you can feel confident and secure.

I want to extend a big thank you to Max and the team for providing clean compounds and always finding ways to provide a better experience. They are bringing the service back into the customer experience and I couldn’t be more grateful to be in business with them. Truly. From the continuous evolution I’ve seen into providing clean products, fixing any issues and putting the focus back on the customer. I trust them and I won’t be going anywhere else for a while.
