The science behind MP-MA
The science

We’d rather show our work

Every active in MP and MA earns its place through peer-reviewed research — dosed at the levels those studies actually used.

Most supplement brands ask you to take their word for it. We’d rather point you to the evidence. Below is a selection of the peer-reviewed research behind our formulas, with direct links to each study so you can read it yourself. No proprietary blends, no hand-waving — just clinically-studied ingredients at clinically-studied doses.

MP · Testosterone — daytime

The research behind your mornings

MP is built around ingredients studied for testosterone support, drive, strength and stress resilience.

  • Ashwagandha KSM-66Strength & testosterone
    In an 8-week randomized, double-blind, placebo-controlled trial, resistance-trained men taking ashwagandha showed significantly greater increases in testosterone, muscle strength and size than placebo.Wankhede et al. — J. Int. Soc. Sports Nutrition, 2015

  • AshwagandhaCortisol & stress
    A 60-day randomized, placebo-controlled study found ashwagandha significantly reduced morning cortisol and self-reported stress in healthy adults.Lopresti et al. — Medicine, 2019

  • ShilajitTestosterone
    90 days of purified shilajit significantly increased total and free testosterone in healthy men aged 45–55 versus placebo.Pandit et al. — Andrologia, 2016

  • Vitamin D3Testosterone
    Men supplementing vitamin D daily for one year showed a significant increase in total, bioactive and free testosterone compared with placebo.Pilz et al. — Hormone & Metabolic Research, 2011

  • ZincTestosterone
    Dietary zinc restriction lowered serum testosterone in healthy young men, and supplementation raised it in marginally zinc-deficient older men.Prasad et al. — Nutrition, 1996

MA · Recovery/Sleep — night

The research behind your nights

MA is melatonin-free by design — built on ingredients studied for deeper sleep, calm and overnight recovery.

  • Magnesium BisglycinateSleep quality
    In a randomized, placebo-controlled trial, magnesium bisglycinate improved sleep in healthy adults reporting poor sleep — the same highly-absorbable form used in MA.Randomized controlled trial — 2025

  • GlycineDeep sleep
    3 g of glycine before bed improved subjective sleep quality and reduced daytime fatigue and sleepiness after sleep restriction.Bannai et al. — Frontiers in Neurology, 2012

  • L-TheanineCalm & sleep
    Four weeks of 200 mg L-theanine reduced stress and anxiety scores and improved sleep-quality (PSQI) measures in healthy adults.Hidese et al. — Nutrients, 2019

  • AshwagandhaEvening cortisol
    The same ashwagandha shown to lower cortisol also supports MA’s job at night: blunting evening stress hormones so the body can recover.Lopresti et al. — Medicine, 2019
