I use it for my blood pressure issues. I would recommend it to others but go to doctor first. Whatever medication the MD puts you on. Take as directed and L-arginine plus once daily as directed. I am a retired RN so if I take it that tells you it is a holistic supplement. Let your doctor be aware. If he thinks it’s useless. I will tell you my B/p improved. I have taken it for years with good results.

!!!!!!!!!!

Great product, can tell at end of workout that it isn’t caffeine driven like others. Great on front end and not jittery on back end of workout.

I have tried many preworkouts in the past and they have made me very jittery and have upset my stomach. This is a great product and has not once made me feel sick to my stomach

Endless energy n no crash!!! I love this supplement as an older aging dad who is starting to take working out n lifting seriously again. Mahalo!!!

I had an awesome workout after taking GroMuscle. I will say that the concentration of Beta-Alanine, and L-Citrulline was higher than I expected, or I’m just no longer used to taking them, and the flush and itchiness got me good. Also, I took the 1st pack about 15 minutes before my workout which I now know isn’t the way to go. 2nd pack I took as I got the gym floor, and man it was GREAT. Been without for 3 days now, and I’m anxiously awaiting my new subscription order.

Taste great good energy boost not too much!

Once I realized to scan the code and to take it immediately, the flush wasn’t bad. Feels like a good primer and I have been able to finish my cross fit WOD with confidence, endurance and strength up.

Best pre workout on the market.

Absolutely in love with the product and the productivity it gives me. Just try it. But stay moving. The first 30-45 minutes gets wild!

I Love L-Argenine and take it pre-workout with other supplements daily.

It’s everything its says it is. Great product. I will definitely buy again.

Top tier preworkout that gets you pumped and the flush is awesome.

Almost two weeks in--so far so good! I can definitely feel it when taking it before working out!

Love it!!
