MG Sports Supplements

Matt Gaines is the most friendly and knowledgeable supplement guru I know. He's always takes the time to discover your goals and help you get to them faster. I love the selection and the fact that I get what I'm looking for at the best prices every time.

I’m from Los Angeles and I travel back and forth, from work. I hold out, just to make sure I stop by Matt’s shop, upon arrival to the SLO area. They’ve always been incredibly helpful when it comes to my fitness journey, as well as general supplement information. Hands down, the best supplement shop I’ve ever been to. Honestly. Will be heading there tomorrow. May God Bless you all.

After going to different supplement shops in town here in SLO over the weekend, and not finding what I was looking for (as well as finding helpful service), I called Matt at MG Sports Supplements this morning and he was incredibly helpful. After work I swung in to pick up my item, and we began to chat about their products and his business (which just celebrated 20 years, congrats!!). They carry a huge selection of items, and if they don't have it in stock, they'll quickly order it for you to have in about 3 days. He told me a story about how a client was looking for some product, they could've ordered it, but helped them out by recommending other nearby shops that would carry what he was looking for since he needed it that day - how rad is that?!? Matt was super cool and very knowledgeable, and I highly recommend talking to him and making MG your go-to shop for sports supplements. I am very much looking forward to going back for more in the future, as well as spreading the word on their professionalism, product knowledge and most importantly, to support local business. MG for the win, thanks again, Matt!

This has been my go to shop for years. Super cool owner. Always willing to give advice and is generally very helpful. Plus great if your looking for supplements you will not find in other supp stores. Great Job Matt!

Recently moved to the area and so glad to stumble on this hidden gem of a shop! Matt made us feel welcomed and shares great knowledge of sports nutrition without being salesy. Seriously, the guy know his stuff and carries an array of high quality, hard to find supplements. I'll be a regular here.

Best prices around! Great selection of top shelf supplements. Knowledgeable staff willing to spend the time to help you meet your needs. Great 70% off selection that helped me find new things I might not have tried otherwise. Plus free tees, hats, and shakers to get you started and help spread the word about the new location. I won't go anywhere else.

Awesome store tucked away in a small shopping center. Great prices and staff are very knowledgeable and orientated with getting you supplements to help with goals at great prices. Was directed to a great protein supplement and creatine. Adds when they’re awesome and kind

Awesome selection and super knowledgeable staff. I like the Ghost protein Chips Ahoy! MG’s been around for over 20 years. Shop local. Support local.

Every time I need anything for my nutritional needs MG Sports Supplements always has my back. With great prices and even better products to choose from. No other place I’d rather go than here.

Great supplement company! Friendly, honest, and fair, (which is why they've been around for almost 20 years and have outlasted all other supplement companies in SLO County!).

Extremely knowledgeable and accommodating. Also does tanning. Great prices, selection, and service!

Great customer service , stacked with best price .
BEAST MODE

Very good service

Dude! This is by far my favorite sports and nutrition supplement shop on the central coast. These guys are knowledgeable about every supplement they carry. I have been going to them for almost a year now, listong my specific health and fitness goals, and they have been steering me in the right direction with the products necessary to help me get my gains and reach those goals every step of my journey. I never review places, but this shop has truly earned my respect so I thought I should give them a shout out. Thanks MG.
