In my case, I did not notice any change in my performance. I don't know if it takes some time to see results, but I stopped it after half a month so as not to burden my body with extra supplements that I see are not needed.

I have never tried such a product before. I bought this one because a friend of mine told me (take it and you will see). Anyway, I have been using it for 4 days. I split it in half. I took half a pill in the morning and the other half in the afternoon. I noticed that while all day I felt drowsy, as the meals are small and frequent, when I started training I had a strange energy. During the sets I put more weight and in the drop set the pump was very intense. That is, I had better blood flow. The first day I didn't sleep well because I may have had hypertension maybe from the extra weight I put on. The next day I had no joint pain and I was not sore. In the workout I put more weight again for my back. The pull-ups on the barbell went up as well as the barbell curls. While the pump and strength were clearly greater. I slept well at night and my watch showed me a lot of DEEP SLEEP time. From the third day I have a nice tingling sensation all over my body. I feel more swollen all day. I will write again after 20 days for more results. So far it seems to work on strength during training and recovery time.
update: I thought it was my idea. It's not, it works. Shorter recovery time and a small but significant increase for a natural strength trainee. I will order more. TAKE IT AND YOU WILL SEE

I have never bought a similar product from other companies before, and I decided to try this one from biontech. It really does the job, it does what it promises! For example, it provides energy, strength, and endurance during workouts, which is why I purchased it. At least during the period I used it, I noticed differences in both energy and muscle growth. Of course, with good and intense workouts, let's not get confused. Yes, these pills are big, but there is no problem in breaking them into smaller pieces and swallowing them easily (for those who find them big and can't swallow them!). As for the claim that it increases nervousness, don't expect anything extreme. I would definitely buy it again!

Excellent product, I usually use Now's Tribulus, but I noticed that Biotech's Tribulus is stronger and better, maybe because of its content of 1500mg per capsule! You should definitely try it
