At the end of 2024 I challenged my closest friends of the last 20 years to a Testosterone Raising Challenge - who could raise their T levels the most for the calendar year 2025. The incentive? I put $1000 of my own money into the pot for the winner. On 1 Jan 2025 I made a few tweaks to these four: Sleep, Diet, Exercise & Targeted Supplements. I was already near optimized with the first three, so my big lever to pull was going to be Target Supplements. For the first 30 days of 2025, I ran this supplement stack with a focus on testosterone optimization, recovery, and overall performance. Here’s what’s in it, why it matters, and the target dosages you should look for. The Stack & Testosterone Benefits ✅ Zinc Bisglycinate – Zinc is essential for testosterone production, as it plays a role in the conversion of cholesterol to testosterone. Deficiency is linked to low T levels, poor immune function, and slower recovery. ✅ Magnesium Glycinate, Citrate, Malate – Magnesium regulates free testosterone levels by reducing sex hormone-binding globulin (SHBG), which binds to testosterone and makes it unavailable. It also improves sleep quality, which is crucial for T production. ✅ Thorne Basic Nutrients 2/Day (with Boron) – Boron has been shown to increase free testosterone levels by lowering SHBG and estrogen. This multi fills micronutrient gaps and ensures optimal hormone function. ✅ Omega-3 with CoQ10 – Omega-3s support testosterone synthesis by reducing inflammation and improving cell membrane integrity. CoQ10 aids mitochondrial energy production, which is key for testicular function. ✅ Vitamin D3 + K2 – Vitamin D acts as a prohormone for testosterone and has been shown in studies to increase T levels when optimized. Essential if you don’t get daily sunlight exposure. ✅ Tongkat Ali – This adaptogen is shown to raise testosterone, working by reducing cortisol, improving Leydig cell function, and supporting libido, strength, and energy levels. The Results After 30 Days - I started with a Total Testosterone of 653 and am currently at 804 (see picture)
