Drug interactions
Winstrol (stanozolol) is an anabolic steroid historically used in veterinary medicine for horses to stimulate appetite, promote weight gain, and treat muscle-wasting diseases or osteoarthritis. Because commercial production has ceased, it must be obtained via veterinary prescription from compounding pharmacies. It is generally banned in competition.Key Clinical UsesWasting Conditions: Utilized to help horses recover from illness, severe injury, or malnutrition by addressing catabolic (muscle-wasting) states and promoting red blood cell production.Joint Therapy: Some equine veterinarians have used stanozolol intra-articularly (injected directly into the joint) to manage osteoarthritis, as it can help reduce inflammation and support cartilage health, though it is not a cure. Side Effects: Like all anabolic steroids, it can cause liver strain, hormonal imbalances, and reproductive issues if misused.Veterinary Control: The drug is highly regulated. Always rely on a licensed veterinarian for diagnosis and appropriate, tailored dosing.Further information regarding how this medication acts on equine joints can be found via Kentucky Equine Research, or by viewing the AAEP clinical guidelines via The Horse.
