What Are The Long Term Effects Of Taking OxyElite Pro?

Hello, I took oxyelite pro 5 years ago for 6 weeks and stopped. I was using it to lose my pregnancy weight. I ate a healthy diet. I stopped and continued a healthy diet and exercise plan. I never felt any side effects and used as directed. I had success. I do not use any supplements now. Is there any long term effects of oxyelite pro? Thank you
