Primobolan, an anabolic steroid used by bodybuilders and athletes, typically does not need to be refrigerated. However, to maintain its stability and effectiveness, it should be stored in a cool, dry place, away from direct sunlight and heat sources. Ideally, the storage temperature should be between 15°C and 30°C (59°F to 86°F). While refrigeration isn't required, keeping the vial sealed and properly stored ensures the longevity of the substance. Always refer to the manufacturer's instructions or consult a healthcare professional for any specific storage guidelines. So, to answer the question, does Primobolan need to be refrigerated? No, but it should be stored correctly to preserve its quality.
