Aquí tienes un título que resume bien la experiencia: Late Shipping, No Customer Support, and Never Received the Product in Time
I paid for the fastest shipping because I needed this supplement urgently, yet it wasn't even shipped until 24 hours after I placed my order. As a result, it didn't arrive on time and was completely useless for the purpose I bought it for. I also contacted the seller to try to find a solution, but I never received a response. I never even had the chance to try the product, so this rating is based entirely on a very disappointing purchasing experience, shipping that failed to meet what was promised, and nonexistent customer service.
