Description
Our liquid cardarine is GW-501516 dissolved in USP-grade PEG-400 at 20 mg/mL, so each 30 mL bottle holds 600 mg. It comes in a glass bottle with a fixed glass dropper, which means you don’t need a separate measuring tool and nothing plastic touches the solution.
Buy liquid cardarine online
Cardarine is one of the most requested compounds in our liquid SARMs range, even though it isn’t technically a SARM. If your protocol calls for weighing dry material, we also sell cardarine powder in a 2 gram pouch. Liquid cardarine also shows up in several of our stacks, including the ostarine and cardarine stack and the SR-9009 and cardarine stack.
What is liquid cardarine?
Cardarine (GW-501516, sometimes called GW1516 or Endurobol) is a synthetic PPAR-delta agonist. GlaxoSmithKline and Ligand developed it in the 1990s as a possible treatment for dyslipidemia, obesity and heart disease. PPAR-delta is a nuclear receptor that switches on genes for fatty acid transport and burning, mostly in skeletal muscle, liver and heart tissue.
It gets sold next to SARMs, but it doesn’t bind the androgen receptor at all. That’s why liquid cardarine is often paired with a true SARM in research: the two act on completely different pathways, and cardarine has no direct effect on testosterone.
Liquid cardarine research findings
In rodent studies, GW-501516 shifted skeletal muscle toward burning fat instead of glucose and raised running endurance. In obese rhesus monkeys it raised HDL cholesterol and lowered LDL and triglycerides. Short human trials looked at lipid profiles and found similar trends.
There’s a serious caveat. GSK dropped the program around 2007 after long-term rodent studies found cancers in several organs at high doses. WADA bans it, and the FDA has never approved it. We think that history belongs on any page selling it, so researchers know what the literature says. You can browse the published work on PubMed.

Measuring and storage
At 20 mg/mL the math is simple: 1 mL holds 20 mg, 0.5 mL holds 10 mg and 0.25 mL holds 5 mg. The full 30 mL bottle holds 600 mg. Draw from the fixed glass dropper and read the volume at eye level.
Keep the cap tight and store the bottle upright in a cool, dry place out of direct sunlight. PEG-400 doesn’t need refrigeration. If the solution looks cloudy after cold shipping, let it sit at room temperature and swirl it gently.
Lab testing and certificate of analysis
Every batch of our liquid cardarine is tested by MZ Biolabs, an independent lab in Arizona, and bottled in the USA. The current certificate of analysis is dated 07/06/25 and shows a purity of 99.57%. We don’t ship a batch until its COA is back, and you’re welcome to ask us for a copy before you order.
Liquid cardarine FAQ
Is liquid cardarine a SARM?
No. GW-501516 is a PPAR-delta agonist. It’s sold alongside SARMs because researchers often study them together, but it doesn’t act on the androgen receptor.
Does cardarine affect testosterone?
It doesn’t bind the androgen receptor, so it isn’t expected to suppress natural testosterone. That’s one reason it’s studied in combination with SARMs.
How should I store liquid cardarine?
Keep the bottle closed, upright and out of direct sunlight in a cool, dry place. PEG-400 is stable at room temperature.
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
Liquid cardarine is sold for laboratory research only. It isn’t a dietary supplement, it isn’t approved by the FDA, and it isn’t for human or veterinary use. We’re a chemical supplier, not a medical provider, and nothing on this page is medical advice. Please don’t buy it for personal use or sports.
