This warning letter advises you of significant violations observed during a U.S. Food and Drug Administration (FDA) review of your website www.buyketaminepowderonline.com (redirected from www.ketaminelab.org). Promptly address the violations described herein without delay, including ensuring that appropriate resources are allocated to fully address the violations and prevent their recurrence. This is not intended to be an all-inclusive list of the violations that may exist in connection with your products or operations. It is your responsibility to ensure that your firm complies with all requirements of federal law, including FDA regulations. Failure to adequately address violations may result in regulatory or legal action without further notice including, without limitation, seizure and injunction.

As discussed below, FDA has observed that www.buyketaminepowderonline.com introduces into interstate commerce an unapproved and misbranded ketamine drug product, which the FDA-approved version is an injectable or subject to a Risk Evaluation and Mitigation Strategy (REMS).1 FDA has identified significant risks associated with unapproved ketamine products, especially in the absence of appropriate medical supervision.2 Given the increased interest in the use of ketamine products, the easy availability of unapproved ketamine products via the internet puts U.S. consumers at risk for serious adverse events. Furthermore, injectable drug products can pose a serious risk of harm to users because they bypass many of the body's natural defenses against toxic ingredients, toxins, or dangerous organisms that can lead to serious and life-threatening conditions such as septicemia or sepsis.3

There are also inherent risks to consumers who purchase unapproved new drugs and misbranded drugs. Unapproved new drugs do not carry the same assurances of safety and effectiveness as those drugs subject to FDA oversight. Drugs that have circumvented regulatory safeguards may be contaminated, counterfeit, contain varying amounts of active ingredients, or contain different ingredients altogether.

Accordingly, FDA requests that www.buyketaminepowderonline.com cease offering any unapproved and misbranded drugs for sale to U.S. consumers. This is critical to shielding the American public from harm.

Violations were identified and documented during a review of your website www.buyketaminepowderonline.com, FDA Establishment Identifier (FEI) 3044408515, in April 2026. Based on our review, your ketamine powder is an unapproved new drug 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 this product for introduction into interstate commerce violates sections 301(d) (21 U.S.C. 331(d)) and 505(a) of the FD&C Act. Furthermore, your ketamine powder is a misbranded drug under section 502 of the FD&C Act (21 U.S.C. 352), and the introduction or delivering this product for introduction into interstate commerce violates section 301(a) of the FD&C Act (21 U.S.C. 331(a)).

The following are violations identified during our review. As a reminder, this is not an all-inclusive list of violations that may exist in connection with your products or operations.

Unapproved New Drug Violations

Based on a review of your website, your ketamine powder is a drug under section 201(g)(1) of the FD&C Act (21 U.S.C. 321(g)(1)), because it is intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease, and/or intended to affect the structure or any function of the body.4 Examples from your website labeling that provide evidence of the intended use (as defined in 21 Code of Federal Regulations (CFR) 201.128) of this product as a drug include, but may not be limited to, the following:

On the webpage www.buyketaminepowderonline.com:• “Neuroscience and Brain Function Research . . . Researchers use Ketamine to model dissociative states and altered neural connectivity, helping to explore cognition, perception, and consciousness at a molecular and systems level.”• “Psychiatric and Mood Disorder Research Models . . . Ketamine is frequently studied in preclinical and mechanistic research related to depression and mood regulation, particularly in examining rapid-onset neuroplastic changes.”

Your ketamine powder is a “new drug” under section 201(p) of the FD&C Act (21 U.S.C. 321(p)), because it is not generally recognized as safe and effective (GRASE) for use under the conditions prescribed, recommended, or suggested in its 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. No approved drug applications pursuant to section 505 of the FD&C Act (21 U.S.C. 355), are in effect for this product. Accordingly, this product is an unapproved new drug. The introduction or delivery for introduction into interstate commerce of this unapproved new drug product violates sections 301(d) and 505(a) of the FD&C Act.

Misbranded Drug Violations

Your ketamine powder is also misbranded under section 502(f)(1) of the FD&C Act (21 U.S.C. 352(f)(1)), in that its labeling fails to bear adequate directions for its intended use(s). “Adequate directions for use” means directions under which a layman can use a drug safely and for the purposes for which it is intended (21 CFR 201.5). Prescription drugs, as defined in section 503(b)(1)(A) of the FD&C Act (21 U.S.C. 353(b)(1)(A)), include those that, because of their toxicity or other potentiality for harmful effect, or the method of their use, or the collateral measures necessary for their use, are not safe for use except under the supervision of a practitioner licensed by law to administer them. Your ketamine powder is indicated for a condition that is not amenable to self-diagnosis and treatment by a layperson, therefore adequate directions cannot be written such that a layperson can use the product safely for its intended use. In addition, your ketamine powder is also a prescription drug as defined in section 503(b)(1)(A) of the FD&C Act, in light of its toxicity or potential for harmful effects, methods of use, or collateral measures necessary for its use. For these reasons, your ketamine powder is misbranded under section 502(f)(1) of the FD&C Act.

The introduction, delivery for introduction, or causing the introduction or delivery for introduction into interstate commerce of this misbranded drug is a prohibited act under section 301(a) of the FD&C Act.

As previously stated, you are responsible for investigating and determining the root causes of any violations and implementing corrective and preventative measures to ensure future and sustained compliance so that these violations and any others do not occur.
