Added energy
I generally run out of energy around 1pm. Taking the L-Leucine helps with my mental alertness and energy without any jitters. This definitely helps me process my calories better.

Easy way to get your dose
I was looking for an easy way to consume this bitter powder. The powder never mixes well in a shaker cup and tastes horrible. The capsules are a quick, easy, and palatable way to get it down. I just wish it came in a higher dosage. Other than that, it was a perfect fit.

62 year old trying to build muscle
I was having trouble building muscle, due to my age. This product triggered my body to build muscle and increased my stammina. Great quality and I will repurchase as my product runs out.

Amino Acid Product
This product was not highly comforting for my body. I was not impressed with the after affect. I was looking to recharge my energy level, and maybe my body was not low in this Amino Acid... Let's Ask another customer to see their difference. Thanks ⭐

Check the source
The product label on this supplement looked suspicious to me. It looked faded. There was a sticker placed over the expiration date, so I peeled it off, and underneath it looked like the expiration date had been removed from the label on the bottle. I have no idea what the expiration date was. I did some more checking, and this product is from the "swehoo store," NOT source naturals. Be careful, people!
