      5/5

      My result

      Bloodwork showed my testosterone was around 460 ng/dL. Increasing vegetables and planning my nutrition improved my mental clarity and performance

      My result

      I got a simple, personalized bloodwork protocol that removed the guesswork and showed me what my diet and supplements were missing

      About the creator

      Callum made it really simple and…easy to follow while still optimizing it. My testosterone was in the mid-to-low 500s, while my vitamin D was already fine, so the bloodwork helped me stop blindly supplementing. I “100%” recommend it, especially for entrepreneurs who need to operate at their highest level

      My result

      My bench press increased from 102.5 kg for 8 reps last week to 105 kg for 8 reps this week. My strength and motivation were at an all-time high

      I felt “pretty good” with testosterone at 750 ng/dL, but testing found low iron, suboptimal vitamin D3, high homocysteine, and adrenal fatigue signs
