Reports and Statistics on Cardarine Defects

Cardarine (GW501516) was initially developed in the 1990s by GlaxoSmithKline (GSK) and Ligand Pharma, as the companies worked together to create a medicine that could potentially halt the formation of tumors in the colon, prostate, and breast tissue.In 2007, GlaxoSmithKline (GSK) halted development of Cardarine after preclinical studies revealed alarming results. High doses in animal models led to tumor development in multiple organs, including the liver, raising serious safety concerns. These findings prompted GSK to abandon further research, signaling potential long-term risks for human use.Medical reports have documented elevated liver enzyme levels in users, a sign of potential liver toxicity. While human case studies are limited, animal research suggests a strong link between Cardarine and tumor growth after prolonged exposure:

  • High doses of Cardarine caused rapid cancer development in rodents, with tumors appearing in multiple organs over a 104-week study [1]
  • Limited human trials (2.5-10 mg/day for 12 weeks) reported no major side effects, but long-term risks remain unknown [2]
  • Cases linked to SARMs, including Cardarine
  • Over 50% of SARM users report mood swings, testicular shrinkage, and acne [3]

Regulatory agencies worldwide have acted against Cardarine due to its unapproved status and safety concerns:

  • The U.S. FDA has explicitly warned against SARMs, including Cardarine, citing significant health risks
  • Countries like Australia have classified Cardarine as a prohibited substance, restricting its sale and use

Cardarine Risks & Safety Concerns

Selective Androgen Receptor Modulators (SARMs) like Cardarine have been linked to severe health complications, some of which can be life-threatening.

  • Cancer Risk: Animal studies show tumor development in multiple organs after exposure; years of exposure may be required before symptoms appear
  • Liver Damage: Warning signs include jaundice, dark urine, abdominal pain, extreme fatigue; symptoms can appear within 7-8 weeks of use
  • Cardiovascular Issues: Chest pain, shortness of breath, irregular heartbeats, fatigue; typically develops within weeks to months of use
  • Heart Attack: Intense chest pressure, pain radiating to arm/jaw, nausea, sweating; can happen suddenly
  • Blood Clots: Swelling, redness, tenderness in the leg or arm; can develop within days to weeks of starting SARMs
  • Deep Vein Thrombosis (DVT): Pain, swelling, and warmth in one leg, difficulty walking; often appears within weeks due to increased clotting risk
  • Pulmonary Embolism (PE): Sudden shortness of breath, chest pain, rapid heartbeat, coughing blood; can occur within hours to days if a clot travels to the lungs
  • Stroke: Sudden numbness, weakness (especially on one side), confusion, slurred speech, vision loss; can happen suddenly with prolonged SARM use increasing risk
