    $10-$20 dollars higher than competing shops in the area. Didn't even purchase anything.

    Their product lineup looks legit -- lots of supplements, protein, vitamins, and performance stuff…read more-- and it seems like they cater to both serious lifters and regular people just trying to stay healthy. The store also looks clean and well set up from photos, and reviews mention knowledgeable staff, which is always a good sign. I haven't made it in yet, but it's definitely on my list next time I'm in the market for supplements and want to support a local spot instead of ordering online.

    The products here are all products I've seen over the years stand the test of time. Brands that try…read moreto reformulate or tweak based on science and feedback. The staff is always attentive at any location I visit and extremely knowledgeable. The price point is on par with purchasing from the brands direct. supplement Giant does a great job marketing by keeping us engaged but not using unrealistic fitness models regurgitating buzz words and pseudo-science. They have actual athletes and local legends to speak to their repertoire of rocket fuels. They don't try to stack cheap shirts and branded things and instead have a tasteful curated select few items allowing us to show our support, which shows me they have integrity and believe in their products. I am anaphylactic allergic to milk and unfortunately allergic to wheat. Those allergies make it difficult to navigate supplements, and I still find options there. At this location Jacob has been exceptionally welcoming and informative in regards to things he can procure if needed, as well as turning me on to products I wasn't aware existed. I do estate gardening/landscaping and am an endurance athlete so, it goes without saying eating can be a full time job, I need supplements to help buy me time between meals and for recovery. I'm so glad to live close to a Supplement Giant again. Thank you so much for your commitment to efficacy and integrity as a business. Thank you for hiring people who seem motivated to help. If I had one wish, it would be for a vegan protein that is strawberry flavored. But, please not pea protein. If you were Santa, I'd ask for a soy-based strawberry vegan protein or a blend. However, I understand supply and demand so, it is what it is. ‍
