  2. Biochemistry Lab
  3. Biotechnology Company

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.

Buyer be Warned

I have been ordering from Max for about a year now and have spent thousands of dollars on the products. When Max first started, he had his mother helping who is a Pharm tech and the products were solid at that time. Once Max moved away, he hired an entire new crew, as I suspect he had a falling out with his parents. I feel it is my duty to warn others of the manipulation, deception, and dishonestly used by Max. First well start with his dishonestly. I posted a few reviews and made comments about discrepancies on his live feeds which were directly removed by him. Second, Max started out telling everyone he is single and heterosexual and is looking for a girlfriend. As a result of him being single and his charm, he used this to give attention to females and gathered a significant female following. Third, he went on a live feed and told everyone if they posted positive reviews in Trustpilot, he would review them and send out free peptides. He was smart though and made sure there was no evidence of this. fourth, he went on a live feed and told the reviewers he went on a date with a man with the attempt to gain more male followers which worked. My last order, which I just used the last vial because I had stocked up, was a while ago. The latest 2 batches that were sent, didn't have any effects, had condensation in the bottle, and had severe degradation. All of these things are dishonest, manipulative, deceptive, and put buyers at a significant risk and loss of revenue. In the meantime, due to his mass followers, high prices, manipulative behavior by stringing men and women along, and nice guy persona, he is now driving a hundred-thousand-dollar car and lives in a multi-million-dollar home. Finally, Max has a multiple diagnosis that has major symptoms of risky and impulsive behavior, and Max has shown he does not put buyers' concerns, well Being, and safety above profit. During the live feeds, he frequently told buyers to start out high when taking Reta, to stack multiple peptides to increase sales, and even mentioned the Hospira brand being the only BAC water to be legit, as testing showed all others came back inaccurate. These deceptive and manipulative behaviors, again, put buyers at risk. Although my order was 4 months ago, I feel buyers need to know of the risks and should go with other peptide companies.

My experience with Mile High Compounds…

My experience with Mile High Compounds has shifted from logistical errors to serious concerns regarding product safety and integrity. While previous issues with missing products were rectified, the quality of recent shipments is unacceptable. Vials arrived with crooked labels and a sticky exterior residue, suggesting poor handling or a breach in container security. Furthermore, the lyophilised powder appeared clumpy and failed to dissolve cleanly, leaving a visible residue after reconstitution. This physical degradation is compounded by a total failure in traceability, as the batch numbers on the vials do not correspond with the provided Certificates of Analysis (COA). Consumers must note that the U.S. Food and Drug Administration issued a formal Warning Letter (721600) to this business on 31 March 2026, citing the sale of unapproved new drugs. Despite the 'nice guy' persona maintained by 'Max' on TikTok, my attempts to raise these technical concerns were met with the immediate removal of my posts. This suppression of critical feedback suggests a deliberate effort to maintain a false narrative of reliability while operating under federal scrutiny. Given these factors, it is evident that the operational longevity of Mile High Compounds is severely compromised.

Hello,

Thank you for the feedback. For context, our records show this customers last order was placed over six months ago, and we have not shipped to Australia in that time.

We take product quality and labeling concerns seriously. If you’d like us to investigate a specific order, please email us at support@milehighcompounds.is with the order number and photos so we can look into it directly.

We’re committed to resolving any legitimate issues and appreciate customers who reach out to us so we can help.
