Counterfeit steroids often come from unscrupulous underground labs, where the precision in dosage, sterility, and purity seen in the top-grade labs or pharmaceutical-grade products is markedly absent. The smaller labs, ranging from sophisticated setups to makeshift operations in garages or basements, frequently lack any form of quality control. The result is a market flooded with products that may contain little to no active ingredients, incorrect substances, or harmful contaminants. Some products are merely vegetable oil, offering no performance enhancement benefits and posing serious health risks. The brand and legitimacy of the steroid you are using can tell you a lot about the quality.

The variability in the content and concentration of these counterfeit products makes them unpredictable and dangerous. Users might believe they are injecting a specific dosage of a steroid, only to be exposed to different concentrations or entirely different compounds. This discrepancy can lead to a myriad of adverse effects, ranging from minor to severe health issues, including but not limited to infections, hormonal imbalances, and irreversible organ damage. This is why you should only use steroids from established and well-known brands; never take the blank bottle special at the gym.
