Unapproved New Drugs Sold Over the Internet

Word for word, from the letter of March 31, 2026

This letter is to advise you that the U.S. Food and Drug Administration (FDA) reviewed your website at https://milehighcompounds.is, which links to your community forum www.skool.com/milehighcompoundsofficial/, from January to March 2026. The FDA has observed that your website offers “GLP-1 SM,” “GLP-2 TRZ,” “GLP-3 RT” and “BAC Water” (hereinafter Mile High Compounds products) for sale in the United States. Based on our review, these products are unapproved new drugs under section 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 355(a). As explained further below, introducing or delivering these products for introduction into interstate commerce violates sections 301(d) and 505(a) of the FD&C Act, 21 U.S.C. 331(d) and 355(a).

These products are especially concerning from a public health perspective because injectable drug products can pose risks of serious harm to users. Injectable products are delivered directly into the body, sometimes directly into the bloodstream, and therefore, bypass some of the body’s key defenses against toxins and microorganisms that can lead to serious and life-threatening conditions.

Despite statements on your product labeling marketing your products for “in vitro research and educational purposes only” and “not for human or veterinary consumption,” evidence obtained from your website establishes that your products are intended to be drugs for human use. Your products are drugs as defined by section 201(g)(1) of the FD&C Act 21, U.S.C. 321(g)(1), because they are intended to prevent, treat, or cure disease conditions and/or affect the structure or function of the body.

Examples from your product labeling, including on your website, that provide evidence of the intended use (as defined in 21 CFR 201.128) of these products as drugs include, but may not be limited to, the following:

BAC WaterYour firm offers “BAC Water” for sale alongside peptide products, which are drugs intended for injection and require reconstitution, including the above-mentioned products. The sale of these products together demonstrates that you intend for your “BAC Water” to be used in combination for injection. Therefore, your “BAC Water” is a drug.

Your Mile High Compounds products are “new drugs” under section 201(p) of the FD&C Act, 21 U.S.C. 321(p), because they are not generally recognized as safe and effective (GRASE) for use under the above-described conditions prescribed, recommended, or suggested in their labeling. With certain exceptions not applicable here, a new drug may not be introduced or delivered for introduction into interstate commerce without an approved application from FDA in effect, as described in section 505(a) of the FD&C Act, 21 U.S.C. 355(a). No approved applications pursuant to section 505 of the FD&C Act, 21 U.S.C. 355, are in effect for these products. Accordingly, these products are unapproved new drugs. The introduction or delivery for introduction into interstate commerce of these unapproved new drug products violates sections 301(d) and 505(a) of the FD&C Act, 21 U.S.C. 331(d) and 355(a).

The violations cited in this letter are not intended to be an all-inclusive statement of violations that may exist in connection with your products. You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations. It is your responsibility to ensure that your firm complies with all requirements of federal law, including FDA regulations.

This letter notifies you of our concerns and provides you an opportunity to address them. Failure to adequately address this matter may lead to regulatory or legal action including, without limitation, seizure and injunction.
