    Awesome Sample Package. Wish more companies did this. It’s a great variety of items to try and a nice bonus shaker cup. I really like the Kre – Alkyn and Karbolyn. It’s a solid company with great products. I will certainly be Ordering a few things.

    These products might work for someone else, but did nothing for me except keep me up all night due to the caffeine content.

    It’s great to find a company that offers sample kits like this as most don’t. Loved everything in it, especially the extra bonus shaker cup – a nice unexpected surprise. I use that everyday. I only wish the samples included a pre workout and BCAAs/EAA’s so I could try those before buying. Otherwise it’s still a sample kit that well worth trying.

    The shaker cup you get is definitely worth it. Best shaker cup around !!!!

    Nice size sample pack of the various products they have to offer. I received a shaker cup to try the protein and Karboyln. I must say I’m impressed with the products I received and will be ordering more for my weightloss goals. Good stuff!

    Not sure why some complain about the $8 shipping? It’s worth it. Great products so far I didn’t know karbolyn existed. I always try to eat some carbs before the gym but sometimes you don’t feel like eating before hand or it just makes you lazy. This drink is great, tastes great works. I haven’t got to the other samples I’ve got some other brand kre alkaline but can’t wait to try out the hardcore and the lyzme5. The shipping was fast. I ordered a few other sample packs from other companies that haven’t even sent the order out yet. That tells alot about how the company is. I will be getting my creatine and that karbolyn from here from now on. Mabe even try a pre-work out seeing how everything alse seems on point.

    First met your reps at the NPC natural Ohio after my show. Great products, the preworkout and karbolyn always hit just right.

    I am a firm believer in EFX products. Listening to Dr. J on crazy Carl’s show is great. I hand out some of these samples to my friends because I believe in the products.

    Got my samples and like all of them. I bought the Karolyn Hydrate, Fuel, andKre-Alkaline at Vitamin Store because I wanted fast. For some reason I couldn’t get any ofmycards to work at checkout. Finally used another email address and it solved the problem and I ordered Lyzme 5 and samples. Looking at the GlutaZorb also with protein drink.

    I think the is a complete and somewhat extensive sample pack, gives you about 2 full doses of each product. Great way to try it before you invest too much money.

    I’m fairly new to the supplement scene so I’ve been doing a lot of testing different products to see what works best for me and my style of training, I’m a mma fighter and I push my training and cardio to the max all the time.. i ordered this sample pack and gotta say I’m apsalutly impressed with ttese products and company, I love the Flavors of all my samples ,everything mixes up extremely well little to no vitamin flavor or chalkyness to the protein shake samples, the pre workout leaves no jitters and complex focus for my training wich is extremely important to me . Didn’t expect the shaker cup love it, great quality shaker … I’m also impressed with the quick delivery on my order .. nice to feel like I found a company that’s not all about the money. EFX Sports just wanna say thanks for making me a priority and thanks for the great products,I will be ordering from you again…

    Quick response! I got the sample and found a new pre-workout prep that worked exceptionally well. I placed my first order. I’m very happy and decided EFX is my new source for supplements.

    Great opportunity to sample their supplement menu. Appreciative to try before I buy. Products packaging, dosage form, and shipment were all top notch. I do recommend.

    I ordered a sample kit after hearing Dr.Jeff, on the SuperHumanRadio podcast, recommending it to test drive the brand. I clicked through the links on the SHR site to here, purchasing was fast and easy. Products arrived quickly and I had more than I expected. I had a small issue with a sample product in the package so I called just to let someone know. Rep on the phone was kind and attentive and insisted on making amends. You guys/gals went OVER AND ABOVE. This is a stand-up company with great products!
