I agree with the PP that it's better to consult a doc first, especially about the dosage. You can easily buy viagra online but taken into account side effects it can cause, I wouldn't risk to take it without a prescription.
Can one hire you as a specialist? My brother started his e-commerce business about a year ago. Now he needs help with product data management. I'm searching online to help him to optimize the work process, to manage all data. Maybe someone has any recommendations here?
