WARNING LETTER
Reference Number: MARCS-CMS 725149
To Legit Ketamine Suppliers:
This warning letter advises you of significant violations identified during a U.S. Food and Drug Administration (FDA) review of your website www.legitketaminesuppliers.com. 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 you comply 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.legitketaminesuppliers.com introduces into interstate commerce unapproved and misbranded ketamine drug products, including certain drugs for 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. Given the increased interest in the use of ketamine products, the easy availability of unapproved and misbranded 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.
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.legitketaminesuppliers.com cease offering any unapproved and misbranded drugs for sale to U.S. consumers. This is critical to shielding the American public from harm.
FDA Review
Violations were identified and documented during a review of your website www.legitketaminesuppliers.com, FDA Establishment Identifier (FEI) 3043543369, on February 26, 2026.
Violations of the Federal Food, Drug, and Cosmetic Act
On your website at internet address www.legitketaminesuppliers.com, you introduce into interstate commerce misbranded and unapproved new drugs in violation of sections 301(a), 301(d), 301(k), 502(f)(1), 503(b)(1), and 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 331(a), 331(d), 331(k), 352(f)(1), 353(b)(1), and 355(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
Certain products offered for sale by www.legitketaminesuppliers.com are drugs within the meaning of section 201(g) of the FD&C Act (21 U.S.C. 321(g)) because they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease and/or because they are intended to affect the structure or function of the body. These drugs are also new drugs as defined by section 201(p) of the FD&C Act (21 U.S.C. 321(p)), because they are not generally recognized as safe and effective for their labeled uses. With certain exceptions not applicable here, new drugs may not be legally introduced or delivered for introduction into interstate commerce without prior approval from FDA, as described in section 505(a) of the FD&C Act.
You failed to obtain approved applications pursuant to section 505 of the FD&C Act (21 U.S.C. 355) for these products that you have introduced into interstate commerce. Accordingly, their introduction or delivery for introduction into interstate commerce violates sections 301(d) and 505(a) of the FD&C Act.
An example of an unapproved ketamine drug product you offer for sale on www.legitketaminesuppliers.com is ketamine marketed as "ketamine buy." Evidence obtained from your website establishing that this product is a drug intended for human use (as defined in 21 Code of Federal Regulations (CFR) 201.128) includes the claim "Ketamine injections are employed in treating acute and chronic pain, particularly in patients who are opioid-tolerant or who have severe, unrelieved pain. It provides pain relief without the severe respiratory depression that opioids can cause."
A second example of an unapproved ketamine drug product you offer for sale on www.legitketaminesuppliers.com is esketamine marketed as "Ketamine Nasal Spray." Evidence obtained from your website establishing that this product is a drug intended for human use (as defined in 21 CFR 201.128) includes the claim “Ketamine nasal spray is a novel treatment primarily used for managing treatment-resistant depression (TRD) and has also shown potential in treating other mental health disorders such as anxiety . . . . "
While there are FDA-approved versions of ketamine drug products on the market in the United States, there are no approved drug applications pursuant to section 505 of the FD&C Act in effect for "ketamine buy" and "Ketamine Nasal Spray" offered by www.legitketaminesuppliers.com.
FDA-approved ketamine, including products marketed under the brand name KETALAR, is a Schedule III controlled substance. It is an intravenous or intramuscular injection indicated as a general anesthetic, including as a sole agent or as an adjunct to other anesthetic agents, for the induction of anesthesia and for diagnostic and surgical procedures. Ketamine is a racemic mixture consisting of two mirror image molecules, R- and S-ketamine (arketamine and esketamine, respectively). This product is only available pursuant to a prescription from a licensed practitioner. Ketamine is not FDA-approved for the treatment of any psychiatric disorder.
FDA-approved esketamine, a ketamine derivative, is a Schedule III controlled substance marketed under the brand name SPRAVATO. It is a nasal spray indicated for treatment-resistant depression in adults and depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior in conjunction with an oral antidepressant. Furthermore, FDA-approved SPRAVATO bears a boxed warning, commonly referred to as a "black box warning," which is the strongest warning FDA requires, indicating that the drug carries a significant risk of serious or even life-threatening adverse effects. The boxed warning addresses the risk for sedation, dissociation, and respiratory depression after administration; the potential for abuse and misuse; the increased risk of suicidal thoughts and behaviors in pediatric and young adult patients taking antidepressants; and the requirement that SPRAVATO be available only through a restricted program, the SPRAVATO REMS, because of the risks of serious adverse outcomes from sedation, dissociation, respiratory depression, abuse, and misuse. The SPRAVATO REMS requires SPRAVATO to be dispensed and administered in medically supervised health care settings that are certified in the REMS and monitor patients for a minimum of two hours following administration. In addition, pharmacies must be certified in the REMS and must only dispense SPRAVATO to health care settings that are certified in the program.
Misbranded Drug Violations
A drug is misbranded under section 502(f)(1) of the FD&C Act if its labeling fails to bear adequate directions for use. "Adequate directions for use" means directions under which a layperson can use a drug safely and for the purposes for which it is intended (see 21 CFR 201.5). Prescription drugs, as defined in section 503(b)(1) of the FD&C Act 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 supervision of a practitioner licensed by law to administer them. Prescription drugs, as defined in section 503(b)(1)(A) of the FD&C Act (21 U.S.C. 353(b)(1)(A)), can be used safely only at the direction, and under the supervision, of a licensed practitioner.
You failed to bear adequate directions for use on the labeling for these drug products that you have introduced into interstate commerce. Because the aforementioned drugs are prescription drugs intended for conditions that are not amenable to self-diagnosis and treatment by a layperson, adequate directions cannot be written such that a layperson can use the products safely for their intended use. Consequently, the labeling for these drug products fails to bear adequate directions for use, causing them to be misbranded under section 502(f)(1) of the FD&C Act. Because these drugs are not approved in the United States, they are also not exempt under 21 CFR 201.115(a) from the requirements of section 502(f)(1) of the FD&C Act. By offering these drugs for sale to U.S. consumers, www.legitketaminesuppliers.com is causing the introduction of misbranded drugs into interstate commerce in violation of section 301(a) of the FD&C Act.
Furthermore, under U.S. law, prescription drugs can be dispensed only pursuant to a prescription from a health care practitioner licensed by law to administer prescription drugs. By offering the aforementioned drug products without requiring a prescription, www.legitketaminesuppliers.com jeopardizes patient safety and misbrands the drug products under section 503(b)(1) of the FD&C Act. Dispensing a prescription drug without a prescription is an act which results in the drug being misbranded while held for sale, in violation of section 301(k) of the FD&C Act.
Conclusion
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.
Send your written response to FDAInternetPharmacyTaskForce-CDER@fda.hhs.gov within 15 business days of receipt of this letter.

Identify your written response with reference number “MARCS-CMS 725149” in the subject line of the email.
If you have information that you believe demonstrates that your products are not in violation of the FD&C Act and FDA regulations, include that information for our consideration.
If you are not located in the United States, please note that products that appear to be misbranded or unapproved new drugs may be detained or refused admission. We may advise the appropriate regulatory officials in the country from which you operate that your products referenced above appear to be unapproved and misbranded products that cannot be legally sold to consumers in the United States.
