Suggested use

Take 1 daily packet with food, or as directed by a healthcare professional.

Foundation is designed as the baseline input layer of the Testosterone I/O system — take it daily for consistent micronutrient support. Hormonal health responds to daily inputs over time, not occasional supplements.

Each packet contains the full capsule system for one day. Vegetarian capsules — no animal products.

Store in a cool, dry place. Keep out of reach of children.

Consult your physician before use if pregnant, nursing, taking blood-thinning medications, managing a thyroid condition, or under medical supervision.

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.

Shipping & returns

• Shipping: Orders are processed within 1–2 business days. Standard delivery takes 3–7 business days depending on your location.
• Returns: You may return or exchange products within 30 days of receiving your order. Items must be in original condition with proof of purchase.

How it works

  1. Packet

    Step 1: Packet

    One daily smart-stack sachet — the full capsule system organized for you. No juggling 30+ bottles, no guesswork, no stacking errors.

  2. Correct

    Step 2: Correct

    Low T often reflects missing micronutrient inputs — magnesium, boron, zinc, and trace minerals modern diets skip. Foundation supplies the vitamins, minerals, and cofactors your body needs to run hormone production pathways properly.*

  3. Consistent

    Step 3: Consistent

    Hormonal health responds to daily inputs over time. Take Foundation every day as the baseline input layer — supporting stress resilience, cellular energy, and the systems testosterone depends on.*

RCT Vitamin D3

Effect of vitamin D supplementation on testosterone levels in men

In a one-year randomized controlled trial, vitamin D supplementation significantly increased total, bioactive, and free testosterone in vitamin D-deficient men — supporting Foundation's 125 mcg D3 dose.
Research Zinc

Zinc supplementation and serum testosterone levels in healthy men

Research shows zinc deficiency can reduce testosterone levels, and supplementation restored normal testosterone in deficient men — relevant to Foundation's 30 mg Albion® zinc bisglycinate.
RCT Ashwagandha

Withania somnifera supplementation on testosterone and reproductive health

In a randomized controlled trial, men taking ashwagandha experienced significant increases in testosterone along with improvements in sperm quality compared to placebo — supporting the 475 mg daily ashwagandha dose.
Research Boron

Short-term boron supplementation and testosterone levels

Research found increases in free testosterone and reductions in inflammatory biomarkers after boron supplementation — relevant to Foundation's 10 mg boron glycinate plus 200 mcg boron citrate.
Review Magnesium

Magnesium supplementation and testosterone in athletes and sedentary subjects

This study showed increased testosterone following magnesium supplementation, particularly with exercise — supporting Foundation's 133 mg magnesium glycinate per packet.
Review Myo-inositol

Myo-inositol supplementation and metabolic health outcomes

Myo-inositol supports insulin sensitivity and metabolic signaling pathways closely connected to endocrine health — relevant to Foundation's 40 mg inositol per daily packet.

Same problem. Very different solutions.

Everything you need to know about Monthlees member pricing, subscriptions, and how checkout works.

What is in each daily Foundation packet?
Each packet is one daily serving with 31 disclosed ingredients: full B-vitamin complex with Metafolin® methylfolate and methylcobalamin, 125 mcg vitamin D3, dual-form vitamin K2 (MK-4 and MK-7), Albion® chelated zinc, magnesium, copper, manganese, and molybdenum, 475 mg total ashwagandha, boron glycinate and citrate, selenium, chromium, inositol, and more. See the consolidated supplement facts panel for every dose.
How is Foundation different from typical testosterone boosters?
Most T-boosters use proprietary herb blends or single-pathway stimulation. Foundation is a micronutrient foundation system — 31 vitamins, minerals, and adaptogens at clinical doses with no hidden blends. It supports the nutritional inputs, stress physiology, and metabolic cofactors testosterone production depends on, not just temporary stimulation.
What results should I expect and how long does it take?
Human clinical studies on key nutrients in the Foundation formula report testosterone increases ranging from ~10% to over 30%, with free testosterone often rising even more due to reductions in SHBG. When deficiencies are corrected simultaneously, improvements in the 15–35% range for total testosterone are biologically plausible within the first month. Individual results vary — consistency with daily use matters. Consult your physician for lab testing and personalized guidance.

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.
