The FDA states that SARMs are not approved and cannot currently be legally marketed in the United States as dietary supplements or drugs. A product being available online does not establish that its sale is permitted.
What does the FDA say?
The agency's SARMs consumer guidance covers unapproved products, associated health risks and enforcement. It specifically addresses products sold with research-use wording.
How US law classifies SARMs
In short: SARMs are not lawful dietary ingredients, and a product intended for human use would be an unapproved new drug.
In the United States, dietary supplements are regulated as a category of food, and a substance that was first investigated as a drug generally cannot later be sold as a supplement ingredient. No SARM has been approved as a drug either. That leaves no lawful route for marketing a SARM for human consumption, which is the basis of the FDA's position. Controlled substance rules are a separate question: proposals to schedule SARMs federally have been introduced in Congress in past sessions, and state rules can differ. Check the current position rather than relying on an older summary.
Does “research use only” make a sale lawful?
In short: no. The FDA looks at how a product is presented as a whole, not just the label.
The label does not settle the question. In a 2022 warning letter, the FDA explained that website claims established intended human drug use despite research-only and non-consumption statements on the labels.
That letter documents the agency's findings in that case. It is not a court judgment or a statement about the retailer's current status.
What the FDA says about the risks
In short: the FDA has warned of liver injury and an increased risk of heart attack or stroke.
The FDA's consumer guidance lists liver injury and acute liver failure, an increased risk of heart attack or stroke, and effects on fertility among the serious problems reported. The published research supports caution: the human trials recorded falls in HDL cholesterol and natural testosterone, and case reports describe liver injury in people using products sold as SARMs (Flores and colleagues, Hepatology Communications, 2020).
What testing of US products found
In short: a JAMA study of SARMs sold online found that many did not contain what the label said.
Van Wagoner and colleagues (JAMA, 2017) bought 44 products marketed as SARMs from internet sellers and analysed their contents. Only about half contained the labelled compound at the stated amount, some contained undeclared drugs, and some contained no active compound at all. That study is one of the main reasons the FDA's warnings focus on product identity as well as pharmacology.
SARMs in US sport
In short: SARMs are prohibited at all times for athletes in tested sport, including in the US.
The United States Anti-Doping Agency applies the WADA Prohibited List, where SARMs sit under section S1.2. Under strict liability, an athlete is responsible for any prohibited substance found in their sample, including from a contaminated supplement. USADA's supplement guidance explains the risks. Doping control laboratories detect SARMs routinely (Thevis and Schänzer, Molecular and Cellular Endocrinology, 2018).
What about possession, research and imports?
In short: possession, genuine research and importation are separate questions from marketing, and this guide does not answer them.
These are separate questions. This guide describes the FDA's public marketing position; it does not determine federal or state possession rules, the requirements for a particular research project, or whether an individual shipment can enter the country.
Do not treat a seller's checkout, delivery estimate or discussion of a proposed bill as permission. The exact product and intended activity need their own assessment.
Is the UK position the same?
In short: no. UK law works differently and has its own guide.
UK rules require a separate review. See our UK SARMs rules guide for that framework. UK dispatch does not establish US permission.
This page provides general regulatory information. It does not establish lawful supply or importation of any product sold on this website.
Frequently asked questions
Are SARMs legal in the USA? They cannot be lawfully marketed for human consumption as supplements or drugs, according to the FDA. Possession and import questions need separate checking.
Are SARMs controlled substances in the US? Scheduling has been proposed in Congress in past sessions and state rules may differ, so check the current federal and state position directly.
Does a research-only label make a product lawful? Not on its own. The FDA has found intended human use from website claims despite research-only labels.
Are SARMs banned in US sport? Yes. USADA applies the WADA list, which prohibits SARMs at all times.
