James! is the man I came in looking for a few specific supplements that he had all the knowledge on he made sure I got exactly what I needed and made me laugh too definitely come see him! read more

I've been stopping by the store since they've opened however recently noticed prices were no longer discounted and actually higher than other places for the same products. Then on top of that they charge you for using your credit card. With the prices being as high as they are, I don't see why they have to charge me for using my credit card. I would understand that if they were actually a discount store. I'll be passing by rather than stopping by read more

Awesome store with plenty of products and AMAZING staff. But their pricing is just crazy. I stopped by last night to grab some Animal brand protein which they just started carrying, but I was shocked to see that they're charging either $67 or $77, I can't remember which, but either is extremely expensive. I ended up just ordering it online and got it delivered this morning already for $46 for the 4lb jar. So if you're in a pinch I'd check them out, but if you don't need it right then and there I'd suggest price checking around first. Edit to reply to the owner- you should inform your staff of the differences then. When asked what I came in for, I said I was looking for Animal brand protein and was taken to the product. I was never informed it was anything other than their regular protein, even when I commented on the price being much higher than onlineit wasn't mentioned. So if you need any help teaching your staff how to correctly inform customers about products you carry so they don't lose sales "just let me know and I'd be glad to help" read more

This guy is cool as shit, he has great taste and EDM music, sometimes I don't know what I'm looking for and he directs me where to go while being professional kind and respectful. This store is right next to my house so it's not that far of a drive and it's right next to the gym so I'll be coming back here indefinitely thank you Walker read more

Brock was a rock star!! Needs a pay raise and a smaller shirt. Solid small site that has pretty much everything you need

Grat products and good prices, friendly staff.! Would recommend going and and learning about the different supplements. read more

I love this place ! Rodney always gives great customer service!! Highly recommend!! Thanks Rodney! I been a loyal customer for over 3 months wouldn't go no where else! read more

Great place good prices and very knowledgeable and helpful people working there !! Definitely 5/5 stars

If I could give them 0 stars, I would. Their customer service is terrible and you should give another store your business.

Nice to have staff working there that also lifts. Not just protein hustlers at the mall.

Everyone has an off day, and that day must have been my first visit. The guys (the owners) are friendly and knowledgeable. Though not informed with some of the most recent studies (if it wasn't part of my training, I probably wouldn't be either), they do not seem to push products they don't believe the customer really needs. I've recommended their website for many of my friends hooked on GNC and bodybuilding.com. Just to give you some of my favs: Preworkout: NOShotGun Protein: Lean Dessert (low carb, so add milk or add a piece of fruit if taken as a recovery supplement) Any NOW supplements: NOW is the best rated supplement manufacturer out there. NO supplement (arginine): MRI NO2 Platinum - could be substituted with NOW A-AKG arginine in a similar dose. ON Casein... great for nighttime protein needs... read more

First visit to this store today and was pleasantly surprised. My regular supplement store has fallen behind on their orders and selections, so I decided to check Supplement Giant out. First impression - well organized and fully stocked with a huge selection! Nick greeted me as I walked in and asked if I needed help with anything. While I did have a few products I needed, I really just wanted to look around and check things out. They had an ample selection to choose from in all categories (protein, pre-work outs, BCAAs, vitamins, etc.) and it looked like the shelves were freshly stocked! I picked up the few things I needed and went to check out. Nick asked if I had been in before, I told him this was my first time, so he explained their philosophy, pricing, etc. and signed me up for their points program, and even threw in a free blender bottle (thanks!). It is a bit out of my way, but this will be my new go-to store for supplements! Their prices truly are the lowest I have seen in-store in Colorado! I have been ordering some things online because my regular store has been out, but Supplement Giant had everything in stock and priced either equal or below online pricing! Hate that I missed their Black Friday specials! read more

This place is like a candy store for me! I like that I can pick up my bodybuilding treats with out waiting for them in the mail! Great prices! read more

Nick greeted us as we walked in the door, said hello and asked if we needed any assistance. After about five minutes he could see that I was going over a few supplements, he asked if I had any questions. Naturally I did, asking for product comparisons. Nick did something that no other supplement shop has ever done. He asked what I was looking for in said products. He then explained what each had, and benefits of each product. No sales pitch, just honest knowledge. Nick went on to suggest gyms for me since I am new to the area. Shook my hand and even remembered my name. If you're looking for supplements, definitely swing by here and check it out. You will be glad you did. Pricing is competitive if not lower than the Internet, and I am pretty sure they price match. read more

After going to GNC and receiving service where they can't give recommendations because they don't know the product- this place was amazing! The customer service was on point. The employees new what they were talking about, let us sample the product which led to us buying. I really appreciate the care they have! And to top it off their inventory was amazing! Absolutely love this place and would recommend it to anyone read more

Best supplement store I have ever been into. Everyone is extremely helpful and super nice. They're very knowledgeable about what they're talking about and will not try to push anything in your face like GNC. Answered all my questions and made sure I left happy. Their prices were cheaper than websites or other places. Will definitely go back read more

Avoid this business and their lack of customer service. I went in with a product that I was trying to return due to not being able to stomach this supplement. Yes I was past the "return window" but being a business owner myself I know rules can bend at any time. All I wanted was a store credit and was going to purchase way more supplements. Due to the crudeness of the employee and the not standing behind a product they sell I will NEVER be going back. For the record I was offered 10% off of a future purchase, or one that day, when I have a product that was bought from your store that smells and like moth balls and was worth $49.99. Obviously you stand behind your employees. Maybe it's start time you start standing behind your product. read more

Supplement giant is hands down the best supplement store for all your needs, if your a beginner to a seasoned fitness person. They will have what you need cause they're a wholesale store, they won't pressure you to buy a certain product. Lowest prices in town. All the guys are super knowledgeable about all the products, so they can help you get what fits your goals/needs. I promise you won't be disappointed! Everyone is super friendly that works at supplement giant too! :) read more

This is my home for all supps hands down? They literally have any and everything, a much better selection than any GNC or vitamin shoppe. If they don't have it they will rush order anything for you. Also their prices beat any competitors out there. A++ read more

This is a fantastic store. The staff is EXTREMELY helpful and aren't in it just to upsell you to some store brand. Huge selection of just about any supplement you can think off. The best part of it all, the prices! you'll be hard pressed to find better pricing online or at another brick & mortar store. read more

Just trust me when I say they have what you are looking for...best prices and a overwhelming supply of top brands. Go get you some really good products for a really good price. And honestly if you wanted to just go in and get some advice they are willing to tell you what each product has in comparison to other products. Good customer service and no sales pitch read more

My BF and I have looked online and in the popular mainstream stores. Supplement Giant has the best prices, most products in stock and most knowledgeable staff. Nick is the best! He has helped my BF create a stack that he loves and is helping me to find products that do what I want/need. The staff is always super friendly, store is always freshly stocked with a wide variety of products and the prices are always comparable or below everyone else's. Did I mention that they are happy to give out samples? We only go here to get our products. I cannot say enough about these guys and this store! They are amazing! You should really stop by and check them out. Tell them Amie sent you! :) read more

I have gone to supplement giant many times as they always have whatever it is i am looking for. I actually live clear across town, but the drive it always worth it. Their prices are as fair as they come, the advice is always spot on. I hope nothing every changes there. Keep up the good work! read more

Great service and knowledgeable staff and offers very good deals. They always take the customer's needs first.

Awesome place! I went to the one off of 88th and Sheridan, we walked in and the guy immediately asked if there was anything he can help with and he had taken us to exactly what we were looking for! Very informative! We are not some really fit people, but they treated us with the same attention they would with actual body builders! Really loved how comfortable we were just being there! read more

this is the best place i'd go to for supplements. better than any other company in colorado

Being new to the Denver area and wanting to get back into shape, I stopped into Supplement Giant in the Bel-Mar shopping center. Stepping in the store I noticed everything sectioned out very nice. Protein powders here, vitamins here, etc. Finding what I was looking for (N.O. Explode) wasn't hard to find at all. Not to mention the gentlemen working there (I would later find out he was the owner) greeted me with a smile and asked me if I needed help with anything. I said "not at the moment" but would later ask him about the N.O. product I was looking at. He explained to me which were the best sellers, best feedbacks, and his personal favorites. He also explained how the N.O. works in the body, how the various products differ and what they contain. He was surprisingly very knowledgeable about the workings of the products for a younger gentlemen. I ended up buying a different product per his suggestion (Black Powder) and couldn't be happier with the product. All in all, it was a great experience. I went in looking for a product but came out a more knowledgeable and happy consumer. Although I have spoken mostly about my product, Supplement Giant has a "giant" selection of items from vitamins to protein bars. Pretty much anything that I had researched online, the store had. The owner was extremely knowledgeable and helpful and the store is very organized and professional looking. If you are working out and want to get a product to help you reach that next level, go to Supplement Giant for a great buying and learning experience. read more
