Liquid SR-9009 (Stenabolic) 20mg/mL

Description

Our Liquid SR-9009 comes ready to measure: 20mg/mL of SR-9009 (Stenabolic) in PEG-400, 30mL per bottle. It’s an REV-ERB agonist. It’s intended for lab and analytical work only.

Background on SR-9009 (Stenabolic)

SR9009 is a synthetic small molecule made in Thomas Burris’s lab at the Scripps Research Institute. It’s often sold next to SARMs, but it doesn’t touch the androgen receptor at all. It binds REV-ERB alpha and beta, two proteins that help run the body’s internal clock.

Its oral bioavailability is known to be poor, so most published animal work gave it by injection. That’s worth knowing when you design an experiment around it.

How SR-9009 works

REV-ERB proteins are nuclear receptors that switch genes off at set times of day, including core clock genes like BMAL1 and genes that handle fat and glucose. SR9009 boosts that repression.

Changing the timing of those genes changes when the liver makes fat, how muscle uses fuel and how much energy the body burns, which is what the mouse studies measured.

What the literature says about SR-9009

Solt and colleagues reported in Nature in 2012 that SR9009 shifted circadian gene expression in mice, raised energy use and reduced fat mass. A year later, Woldt and colleagues reported in Nature Medicine that it increased mitochondria in skeletal muscle and improved running endurance in mice.

Later work, including a 2019 paper in Cell Metabolism, found that some of its effects still showed up in cells lacking REV-ERB, so researchers now treat it as a tool with possible off-target activity.

SR-9009 and its alternatives

Quick context: SR-9009 is a REV-ERB agonist that acts on the body clock and muscle metabolism in mice. Other compounds in the same area:

• Cardarine is a PPAR-delta agonist studied for endurance and fat burning in mice
• MK-677 is an oral ghrelin mimic that raises GH and IGF-1 and isn’t a SARM
• MK-777 is an acetylated version of MK-677 with very little published data
• RU-58841 is a topical antiandrogen that blocks the androgen receptor instead of activating it
• Ostarine is the most studied SARM, with human trial data on muscle wasting

These are often sold next to SARMs but work through other targets: PPAR-delta, REV-ERB, the ghrelin receptor or androgen blockade. Compare them in our liquid SARMs.

How Sports Technology Labs tests Liquid SR-9009

The current certificate of analysis shows 99.37% by HPLC. The testing is done by MZ Biolabs, an independent lab in Tucson, Arizona, which also checks identity by mass spectrometry.

You’ll find the COA in the photo gallery above. Open it and check the date, the method and the purity figure yourself.

HPLC and mass spec answer different questions. HPLC tells you what share of the sample is the main compound. Mass spec tells you the compound is the right molecule. A COA with only one of them leaves a gap.

If anything arrives wrong, the 60-day money-back guarantee covers it.

Liquid SR-9009 concentration and measuring

Each 30mL glass bottle holds 20mg of SR-9009 per mL in USP-grade PEG-400, 600mg in total. A graduated 1mL glass pipette comes with every bottle.

Because the strength is fixed, volume converts straight to mass. 1mL is 20mg, 0.25mL is 5mg. PEG-400 is viscous, so draw slowly and let the pipette drain fully.

Storing Liquid SR-9009

A cool, dark shelf is ideal. Keep the cap on between uses so the solution doesn’t pick up moisture.

Label the date you opened the bottle so your records match your results.
