This has been amazing for me. It has helped me relax and be ready for a good nights sleep. I'm going to purchase again and have my husband try it.
I finally started waking up feeling rested. Before, no matter how many hours I slept I would wake up feeling like I hadn't slept at all. It's not a miracle fix of course. I also took some other steps to improve my sleep, but it definitely makes a difference!
Excellent product to help us regain tranquility and sleep. I am very satisfied with the results; I feel more energetic and motivated every day. It contains very beneficial ingredients for the body such as magnesium glycinate, taurine, lemon balm, and lavender, among others, which provide many benefits for our body.
This has been an amazing supplement for me. I really liked Heart of Steel 10-in-1 I've been using it regularly. I have noticed that I have more energy. And I have better workouts. It has also improved focus throughout the day. The combination of these different really helps with my circulation and endurance. I haven't seen any side effects that some people talk about when taking these supplements. I will be purchasing this supplement again.

I love this product. I find it so convenient as it contains several things I have been taking seperately. Now, it is my all around super-charger.
bought the Formulation Factory Self Obsessed Starter for my fianc, and we've both noticed a difference. After a couple of weeks, he's had noticeably better energy, motivation, and overall drive. His workouts seem stronger, and he's more focused and consistent throughout the day without any crash.
What I really like is how well-rounded the ingredient list is it feels like a clean, thoughtfully formulated supplement rather than something overly harsh or stimulant-heavy. He hasn't had any negative side effects, and the capsules are easy for him to take.

This is on auto ship and love the benefits. The cost is worth it & they are easy to swallow!
Almost a month since I started taking it. Now I can share my experience. As a 40-year-old woman who is also overweight, I noticed a real difference. It gave me more steady, natural energy for my workouts without the jitters, and I felt less sore the next day. I also felt a bit less puffy overall, which was a nice bonus. It's been a great support for my fitness goals.
My new go to supplement for overall health and support for my workouts. This supplement is easy to take and easy on my stomach.

I've been using Heart of Steel for a while now and I'm really happy with how it feels. The energy is smooth and steady without jitters or crashes, which is very important for me. It works well both for workouts and busy days.
I like the ingredient profile it feels well thought out and balanced. I didn't experience any stomach discomfort or nervousness while taking it.
