Description
The MK-677 cardarine and SR-9009 stack is the only three-bottle set we sell with no androgen receptor ligand at all. It’s built for metabolic and growth hormone research.
Buy the MK-677 cardarine and SR-9009 stack online
You get three full bottles: liquid ibutamoren, liquid cardarine and SR-9009 liquid. Buying them as a stack costs less than ordering each bottle on its own, and everything ships together in one package. Each bottle is filled from a batch with its own certificate of analysis, and each one has its own pipette, so there’s no cross-contamination between compounds.

What’s in the MK-677 cardarine and SR-9009 stack?
Ibutamoren (MK-677) is an oral growth hormone secretagogue. It acts on the ghrelin receptor and raises growth hormone and IGF-1 without touching the androgen receptor. Cardarine (GW-501516) is a PPAR-delta agonist. It shifts muscle toward burning fat and has no androgen receptor activity. SR-9009 (stenabolic) is a REV-ERB agonist from Scripps Research that links the circadian clock to fat and glucose metabolism.
MK-677 raises growth hormone. Cardarine and SR-9009 both affect how muscle and liver handle fat, but through different receptors, PPAR-delta and REV-ERB.
Research behind the MK-677 cardarine and SR-9009 stack
Cardarine and SR-9009 are often compared because both raised endurance in mice. They do it differently: cardarine shifts muscle toward fat burning, while SR-9009 changes circadian gene activity and mitochondrial numbers.
MK-677 adds a growth hormone signal on top. Read the REV-ERB work on PubMed before planning a combined protocol.

Measuring and storage
Each compound comes in its own glass bottle with a graduated 1 mL glass pipette, so you can measure each one separately and keep your records clean. Label your draws by bottle, because the solutions look alike.
Store all the bottles upright, tightly capped and away from heat and direct sunlight. Room temperature is fine for PEG-400 solutions.
Lab testing and certificate of analysis
Each bottle in the MK-677 cardarine and SR-9009 stack comes from a batch tested by MZ Biolabs, an independent lab in Arizona. MK-677: 99.97% (COA 11/17/25). Cardarine: 99.57% (COA 07/06/25). SR-9009: 99.68% (COA 09/23/2025). Ask us for the full certificates and we’ll email them over.
MK-677 cardarine and SR-9009 stack FAQ
Does this stack contain any SARMs?
No. All three compounds act on non-androgen pathways.
Why pair cardarine with SR-9009?
Both affect fat metabolism and endurance in mice, but through different receptors.
What concentrations are included?
MK-677 at 25 mg/mL, cardarine at 20 mg/mL and SR-9009 at 20 mg/mL.
Why researchers buy from Sports Technology Labs
A 2017 JAMA study bought 44 products sold online as SARMs and tested them. Only 52% contained a SARM at all, and 39% contained other unapproved drugs. That’s the problem we set out to fix. We start with raw material that’s at least 98% pure, bottle everything in the USA and send every batch to MZ Biolabs before it goes on sale. Liquids go into glass bottles with glass droppers, so there’s no plastic in contact with the solution.
Shipping, returns and support
Orders over $149 ship free inside the US, and express shipping is there at checkout if you’re short on time. Everything we sell is covered by a 60-day money-back guarantee. Questions about a batch, a COA or an order? Email us and a real person will answer.
For laboratory research use only
The MK-677 cardarine and SR-9009 stack is supplied strictly for laboratory and analytical research. It is not approved by the FDA, is not a dietary supplement and must not be used in people or animals. Nothing here is medical advice, and we won’t sell it for personal or athletic use.
