Using Stud 100 Male Delay Spray is super easy. Just spray it on your penis 5 to 15 minutes before having sex. This gives the mild anesthetic enough time to work its magic. There's no need to get a prescription or see a doctor first. Remember, this spray is designed to help with premature ejaculation and make your intimate moments last longer. As for maintenance, keep it in a cool and dry place. Don't expose it to extreme temperatures. If you have any allergies or health concerns, it's a good idea to do a small patch test first. And always follow the usage instructions to get the best results and ensure your safety.
