US legal status	Not FDA-approved for human use. Sold exclusively as a research chemical. WADA-banned. No approved pharmaceutical product.

What is SR9011?

REV-ERB nuclear receptor agonist (related to SARMs mechanistically). Synthetic compound developed to modulate circadian rhythm regulation and metabolic pathways. Not a traditional androgen receptor SARM.

How it works

Activates REV-ERB alpha (nuclear receptor) which regulates circadian gene expression and metabolic homeostasis. Pathway distinct from androgen signaling; effects on human circadian biology unknown.

Background & history

Developed by academic researchers studying circadian biology and metabolic regulation. Preclinical animal studies only; development terminated before human testing phase.

What the research says

Preclinical and animal research only. Limited human evidence; no published human trials. Animal studies report effects on circadian function, metabolic rate, and endurance capacity. Mechanism involves nuclear receptor activation distinct from traditional androgen pathways.

Reported effects

Studied for potential metabolic rate effects in animals
Reported circadian rhythm modulation in preclinical work
Preclinical research on endurance and exercise capacity
Nuclear receptor activity distinct from androgen pathway
Human research severely limited

Dosing & administration (informational)

Preclinical research employed dose ranges selected for circadian and metabolic read-outs in rodent models. No translation to human pharmacokinetics attempted.

This is general research/context information, not medical advice or a recommended protocol.

Safety & side effects

No human safety data; completely unvalidated in people
Unknown organ impact; circadian disruption possible
Animal studies limited; long-term effects unknown
WADA-banned; sport use prohibited
Unregulated sourcing; contamination risk extremely high
Experimental mechanism means unpredictable human responses

Drug & supplement interactions

Unknown interaction with endogenous REV-ERB ligands and co-regulators
Potential for circadian desynchronization with concurrent shift work
May alter hepatic metabolism of other compounds through clock gene effects
Unpredictable effects on sleep-wake cycle in humans

Who should avoid it

In individuals with sleep disorders or circadian rhythm disruptions
Concurrent use with other metabolic modulators
In those planning shift work or altered sleep schedules
During sport competition (WADA-banned) or healthcare professions requiring alertness

How it is commonly combined

No human evidence exists; combination with other research compounds unpredictably alters circadian and metabolic homeostasis.

Legal & regulatory. Not FDA-approved for human use. Sold exclusively as a research chemical. WADA-banned. No approved pharmaceutical product.

Lab testing & harm-reduction tools

If you are going to research a compound, verifying identity and purity is the single most protective step. Independent analytical testing and sterile-handling supplies reduce risk.

Frequently asked questions

Is SR9011 a SARM?

Mechanistically related but distinct. It targets REV-ERB nuclear receptors, not androgen receptors directly. Still unproven in humans.

What is it supposed to do?

Preclinical research suggests circadian and metabolic effects, but human evidence does not exist.

Why use it instead of other compounds?

Unknown benefits in humans; anecdotal interest only. No scientific advantage demonstrated.

What are the main concerns?

Zero human data, unknown organ effects, WADA-banned, unverified product purity, and completely experimental mechanism in people.

How does circadian disruption risk manifest?

Unknown; potential for sleep-wake cycle disturbance, metabolic dysregulation, and unpredictable endocrine effects.
