GW 501516 by Dragon Pharma
What Is GW 501516?
GW 501516 by Dragon Pharma is an oral research compound also known as cardarine or endurobol. It is not a SARM and not a steroid: GW-501516 is a PPAR-delta receptor agonist, which means it works through a receptor family that regulates fatty acid metabolism and energy usage in muscle tissue. Research interest centers on endurance, fat oxidation and overall conditioning rather than direct muscle building.
Each Dragon Pharma tablet holds 20 mg of GW-501516 and the pack contains 100 tablets. The most commonly referenced research dose is 10-20 mg per day, taken orally for a defined block, most often 8-12 weeks. Users describe a noticeable shift in endurance capacity and a leaner look when training output and diet are in place, which is why cardarine sits in the cutting and conditioning category of research products.
GW-501516 has a serious caveat that any researcher must understand: development as a human drug was halted after high-dose, long-term animal studies raised tumor concerns, and the compound is banned in competitive sport. It remains an experimental research chemical sold only for laboratory study, not for human use.
GW 501516 Research Use
GW-501516 is dosed orally and is one of the simplest research compounds to run from a logistics standpoint - no injection, no reconstitution. The discipline is in the schedule and the defined block length.
| Parameter | Reference value | Note |
|---|---|---|
| Research dose | 10-20 mg per day | One 20 mg tablet can be split into a 10 mg dose |
| Schedule | Once daily | Consistent timing keeps plasma levels steady |
| Research window | 8-12 weeks | Follow with an equal break off the compound |
| Effect onset | 1-3 weeks | Endurance shifts usually appear before visual changes |
| Overtraining context | Conditioning blocks | Cutting or endurance phases, not mass building |
Cycle Length
Effects are training-dependent: GW-501516 is studied as a metabolic modulator, so the outcome shows up as greater work capacity and better fatty acid utilization rather than instant changes. Blood lipids and markers should be checked before and after a research block, and the compound should never be run longer than a defined window given the safety questions from animal studies.
GW 501516 Stacks
GW-501516 is placed in cutting and conditioning stacks where endurance and fat metabolism are the goal. All partners below are Dragon Pharma products and each is chosen for a different angle of the same conditioning phase.
| Stack partner | Role in the stack |
|---|---|
| Clenbuterol | Stimulant fat-loss partner for aggressive conditioning blocks |
| Salbutamol | Milder beta-2 alternative for fat loss without heavy stimulation |
| T3 | Thyroid support used in deeper metabolic cut protocols |
| Anavar 10 | Androgen partner for preserving lean tissue while cutting |
| Winstrol 10 | Drying oral for contest-style conditioning phases |
| L-Carnitine 500 | Fat metabolism support that lines up with PPAR-delta research |
Research stacks pair cardarine with stimulant or metabolic partners only in short, well-planned blocks, and the safest arrangement keeps total stimulant load moderate. Because GW-501516 does not suppress testosterone, it is also a common add-on for endurance work between androgen phases.
GW 501516 Side Effects
GW-501516 has a mild short-term side effect profile in the doses commonly referenced, but it carries one safety question that completely changes how it should be treated.
- Short-term effects: occasional headache, mild gastrointestinal upset and sleep changes are reported at the start of a run.
- Blood markers: GW-501516 can shift lipids and blood sugar metabolism; monitoring is part of responsible research use.
- Sport ban: cardarine is prohibited by WADA and most sports federations at all times.
- Not hormonal: it does not suppress testosterone, which is a common reason researchers place it between androgen cycles.
GW-501516 is an experimental research chemical sold for laboratory research only. It is not approved for human use and is banned in competitive sport. This text is not medical advice.
What is GW 501516 (cardarine)?
GW-501516, also called cardarine or endurobol, is a synthetic PPAR-delta receptor agonist developed as a drug candidate for metabolic and endurance research. Dragon Pharma supplies it as 20 mg oral tablets for laboratory study.
Is cardarine a SARM?
No. Cardarine is often grouped with SARMs in shops, but it is not a SARM and not an androgen. It activates PPAR-delta, a receptor involved in fatty acid metabolism and endurance, so it has no testosterone-receptor activity.
What does cardarine do?
GW-501516 research focuses on increased fatty acid oxidation and endurance capacity. Users typically report better conditioning, longer work capacity and a leaner appearance during a cut, rather than direct muscle growth.
How much cardarine should I take?
The most commonly referenced research dose is 10-20 mg per day, taken orally once daily. The Dragon Pharma 20 mg tablet can be split in half for a 10 mg starting dose.
How long does cardarine take to work?
Endurance and conditioning changes are usually noticed within the first 1-3 weeks of consistent dosing. Visual changes depend on diet and training and typically develop over a full 8-12 week research window.
Does cardarine suppress testosterone?
No. GW-501516 is not hormonal and does not suppress natural testosterone, which is one reason it is used in conditioning blocks and between androgen cycles. It should not be confused with SARMs in this regard.
What are the side effects of cardarine?
Short-term reports include headache, mild gastrointestinal upset and sleep changes. The serious concern is long-term animal data: high-dose rodent studies showed tumor growth, which is why GW-501516 was never approved and why research use should stay short and defined.
Is cardarine legal?
GW-501516 is not an approved medicine and is sold for laboratory research only. It is prohibited by WADA and most sports federations at all times, and athletes should never use it near competition.
What can cardarine be stacked with?
Common conditioning stacks pair cardarine with fat-loss partners such as clenbuterol, salbutamol or T3, or with anabolic partners like Anavar or Winstrol when lean tissue preservation matters. All partners are available in the Dragon Pharma catalog.
Where to buy cardarine online?
Dragon Pharma GW 501516 is available in this shop as a 100 tablet pack of 20 mg cardarine. It is an experimental research chemical supplied for laboratory purposes only, not for human consumption.
