Check the supplier’s legitimacy. Confirm their registration with relevant authorities and verify their physical address. Look for independent reviews and testimonials.
Packaging and Labeling
- Examine the packaging for inconsistencies. Look for blurred printing, spelling errors, or unusual fonts. Counterfeit products often have poor quality printing. Verify the batch number and expiry date. These should be clearly visible and easily verifiable through the manufacturer’s website (if available). Check for a tamper-evident seal. This seal should be intact and unbroken. A broken seal suggests tampering. Compare the packaging to images of authentic Viagra packaging found on reputable pharmaceutical websites.
Request Certificates of Analysis (CoA). Legitimate wholesalers should provide these documents that verify the product’s composition and purity.
Supplier Due Diligence
Request references from the supplier. Contact previous clients to inquire about their experience. Check the supplier’s history. Investigate whether they have any legal issues or negative reviews online. Use secure payment methods. Avoid transferring money through untraceable channels. Ensure proper documentation. Obtain invoices and delivery receipts. Secure all communication records.
Pill Characteristics
While visual inspection is not definitive, observe the pills. Genuine Viagra pills have specific markings and consistent color, size, and shape. Deviations could indicate counterfeits. Compare to images of authentic pills from reputable sources. Use this information cautiously, as visual inspection alone isn’t sufficient.
Professional Testing
Consider independent laboratory testing. A reputable laboratory can analyze a sample to verify the active ingredients and confirm the absence of harmful substances.
