Why We Do It
Hear from our satisfied customers who have experienced the quality and value of Custom Gains
Custom Gains has completely changed the way I approach my workout supplements. The ability to choose exactly what ingredients go into my pre-workout, mid-workout, and post-workout blends is a game-changer. I love how easy the website is to navigate—it guides you through the selection process so you can create the perfect mix tailored to your specific goals and preferences. The quality of the ingredients is top-notch, and I’ve noticed a significant improvement in my performance and recovery. If you’re serious about your fitness and want supplements that are customized just for you, Custom Gains is definitely worth checking out. It’s been a fantastic addition to my fitness routine!

I can even customize my protein powder, adding extras like creatine or melatonin as I see fit. It’s an unprecedented level of flexibility. I’ve named my personalized pre-workout ‘Petty’ and my protein blend ‘Tucked In’ – having the option to name my custom mixes adds a fun, personal touch. This degree of control over my supplements is truly game-changing.

Lexie Petty
Even having my normal Pre Workout recipe but with Custom Gains is cheaper. And now I have the convenience of a packet as a serving too… no brainer

Casey Williams
I’m a mom of 4 and I don’t take Pre or Post, but I do take the Mid drink. I created it so I can stay focused and hydrated for my long days of playing with my girls and when I need to work from home.

Riley Brown
I work as a pipe fitter and man are the days long. I don’t need a pre, but heck yes I need a Mid and Post day drink. I normally take melatonin on the side to help with sleep but now I just drink my favorite watermelon protein, to which I added melatonin and ashwagandha, I’m lights out for 8 hours of rest.

Cameron Miller
Finally, finally, I have a pre where i can load up the ingredients no more half-dosed ingredients, and scooper. My pre, my buddies cant handle it, but that’s fine with me. I want high everything stim and pump. I just ordered my Mid Workout drink to help sustain my long lifts and days at school. Need more focus in class so added Custom Gains ingredients that were suggested for focus during the beginner guide creation. Highly recommend!!!

How We Are Different
Fully Customized By You
If you are unique, why opt for standard supplements? Review your current supplement lineup – is there room for adjustments to cater more specifically to your individual needs? If a particular ingredient triggers allergies, eliminate it. Customize your supplement routine to match your distinct requirements and enhance your overall well-being.
Every serving is individually packaged
Why deal with the inconvenience of a non-travel-friendly tub and worry about getting accurate ratios with a scooper? Opt for Custom Gains where each serving is in individual packets, making it easy to take multiple packs on trips or bring one pack with you wherever you go for consistent optimal results.
You Can Even Change the sweetener
Do you hate Sucralose? With Custom Gains you can choose even your sweetener if you want! Try Monk Fruit, Stevia, or Erythritol.
Any Flavor For Any Occasion
Are you looking for the typical pre-workout in blue raspberry flavor, or are you interested in trying out different flavors without compromising on dosage? Your preference for a chocolate flavor over blue raspberry shouldn’t limit your choices only to protein supplements. With Custom Gains, you have the freedom to select any flavor to suit your mood or occasion.
The Road Ahead
Custom Gains isn’t just about selling packets—it’s about fostering a movement of self-driven achievers. We have new flavors and formulas in the works, plus community events and challenges on the horizon. Together, we’re redefining what it means to truly “own your gains.”
