A product can contain the wrong drug, a different quantity, or microorganisms. Chemical testing and sterility testing answer different questions; neither is implied by an attractive label.
Chemical identity is one problem
Van Wagoner and colleagues analysed products marketed online as SARMs and found a substantial mismatch between labels and chemical contents. That study concerned chemical identity and quantity; it did not establish sterility or the quality of every product on today's market.
A plausible label, web photograph or one manufacturer's certificate cannot establish what is in a specific purchased unit. Batch identity matters, especially where supply chains or repackaging are opaque.
Microbial safety is another
Injectable preparations add risks from contamination and the injection process itself. Published clinical accounts of infection after anabolic steroid injections illustrate the consequences of failed sterility, while a clear liquid or sealed vial cannot demonstrate microbial safety.
A chemical purity result does not show that a product is sterile. Conversely, sterile manufacture would not prove the declared active ingredient and concentration are correct.
Responding to signs of infection
Spreading redness, warmth, swelling, fever or worsening pain following an injection calls for medical assessment. Severe illness, rapidly spreading symptoms or confusion requires urgent care.
Be candid about what was used and bring packaging or documentation if available. This is about enabling treatment, not validating the supplier's claims.
In short
- Chemical contents and microbial sterility require separate evidence.
- A certificate for another batch does not verify the product in hand.
- Fever or spreading redness following injection needs medical assessment.
