Let customers speak for us
Love these gummies! They help me get to sleep quickly (in about 30 mins or less) and generally not too groggy waking up. I stay asleep through the night for the most part (probably still need to optimize some other things like eating before bed, screen time, etc) but these things are amazing and (and taste good too, a nice little treat before bed haha).
I've been a beachbody pre workout fan for 10 years, so it's hard to pull me away from my staple, but in trying the SFL pre workout I have to say it is not only tasty, but also everything one would need to get through an intense workout. There is no crash or jitters and it definitely delivers!
this helps make me feel like I’m not 40. Running around with all the energy in the world off of this powder. Who would have known…
I’ve been taking these Lion’s Mane gummies daily for a couple weeks and I’ve noticed a real difference in my focus and mental clarity—especially during the midday slump when I usually lose steam. They taste great too (no weird aftertaste) Definitely a new staple in my routine!
Usually I feel tweaked out. This stuff has no crash, tastes amazing and I get a great workout in. No shakes from this
Can't believe how much weight I've lost, as well as the impacts on my daily mental clarity. Good solid product, everyone should be taking this!
Felt an immediate difference when blending in with my protein. Will be purchasing again, thank you!
Found my body getting healthier by the day when I took it for allergies this spring. Will be getting again!
DELICIOUS!!! Such a good flavor and I love that it's made with L Theanine so there's literally no crash :)
Ordering was easy and I received the shipment quickly. I've received compliments on it. It was a wise choice to "size-up." I'm 6 feet tall, 180 pounds and the XL (after washing) fits me perfectly. Will order again.
Super helpful when it comes to falling and staying asleep! Thank you!!!
I would absolutely recommend this product to anyone who's looking to start using Creatine. It dissolves well, I feel better using it and will be buying again. The price is lower than other popular creatine brands and it stands up to any other in terms of quality. The packaging is great!
Love taking this, it works, I feel better and sleep better. What else ya need?
Thank you guys so much! Great design and awesome fitb was a gift to my partner!
Noticed an improvement in my joints after just 4-5 days of taking it. Will be buying again.
