Company details
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.

Transparency, Quality and Service I Can Trust
I initially chose MHC after seeing favorable reviews and ratings and was pleasantly surprised by how quickly my first order was filled, shipped and received. I continued looking at other suppliers, but after navigating through the endless number of alternative sources, I have yet to find another that offers such consistent and comprehensive testing across their entire product line. MHC will be my go-to choice for my research needs and would highly recommend them for their commitment to quality standards and customer service.

Awesome service and packaging!
The efficiency of which this company gets out their product is absolutely amazing! I’ve just started my peptide journey, so it’s too early to explain the benefits I’m having, but I’m encouraged by the quality of peptide I’m receiving.

I love the rigorous testing on peptides, great customer service, and seamless/fast delivery I receive from Mountain High Peptides. I feel confident when ordering and utilizing their products. Professional, easy-to-read packaging and labeling, along with access to batch testing for concentration, heavy metals, contamination, etc., bring peace of mind to consumers like me.
