Ultimate Stamina

Great products! It’s been about 2 weeks and I can notice a difference in my performance during workouts as well as private recreation 😉. I even notice that my mood is a bit better and I sleep better at night. Maybe from all the extra reps? Either way, great products. Just ordered the energy bundle a couple days ago and looking forward to seeing how those work as well. Thank you EC Sports for making supplements that actually work without draining my wallet 🙌🏽👍🏽

Good value

I can tell a drop off if I do not take this supplement. It is a good way for me to keep energy up for the gym. I have a low metabolism and this certainly helps some. I will continue to purchase it.
