About monthlees
The supplement industry is built on inflated pricing, confusing labels, and aggressive marketing.
Monthlees exists to fix that.
We believe:
- Supplements should be clinically dosed
- Pricing should be transparent
- Testing should be independent
- And customers shouldn't pay for influencer commissions or retail margins
Instead of hiding costs inside the product price, we use a simple membership model — so you pay what supplements actually cost to make.

How is Melon Creamsicle different from other Energenix flavors?
Melon Creamsicle shares the same active formula as Fruit Punch, Cotton Candy, and Lychee Blast — 200 mg green tea caffeine, 100 mg L-theanine, 1,000 mg taurine, B vitamins, and electrolytes per 2 scoops (7 g). Guava Berry uses the same actives in 2 scoops (6 g). Choose based on flavor preference; supplement facts doses are identical across the 7 g flavors.
How much caffeine is in each serving?
Each serving (2 scoops, 7 g) delivers 200 mg natural caffeine from green tea, paired with 100 mg L-theanine, as listed on the supplement facts panel. One container provides 20 servings.
When should I take Energenix Melon Creamsicle?
Mix 2 scoops with 8–12 oz of water 20–30 minutes before exercise or when you need sustained energy and focus. Avoid use close to bedtime if you are sensitive to caffeine.
Why I created monthlees...
When I was 19 years old, I was diagnosed with a brain tumor. That experience forced me to start asking deeper questions about how the human body actually works.
Over the next 18 months, I immersed myself in studying health, nutrition, and neuroscience — eventually earning my degree in Neuroscience from Duke University. Along the way, I discovered something powerful: the body is incredibly resilient & inherently self-healing when it’s given the right support.
Strategic nutrition and supplementation became a major part of my own health journey. And over the last two decades, I’ve devoted my life to helping millions of people around the world take a more proactive role in their health.
That experience completely changed how I thought about health — and ultimately shaped the way Monthlees was built.
I created Monthlees because I was tired of seeing people pay premium prices for supplements that were under-dosed, over-marketed, and difficult to trust.
My goal is simple: build the kind of brand I would want for myself and my family — with better ingredients, transparent formulas, meaningful dosages, and a business model built on long-term trust.
