Eight years of bloodwork sit in a folder on my desktop. Not because I am obsessive. Because I got tired of not knowing. Every supplement I had ever bought, every protocol I had ever followed — none of it told me whether anything was actually working.

So I started measuring.

What "the protocol" actually means

A protocol is a system with feedback. You run it, you measure it, you adjust it. If there is no biomarker, no tracked outcome, no before and after — it is not a protocol. It is a habit. Habits are fine. But habits do not compound the way a real protocol does.

The number that matters is never the one on the label. It is the one in your bloodwork.

What the evidence shows

Magnesium Glycinate400mg nightly. Moves rMSSD within weeks. The most common deficiency in active men. Standard blood tests miss it — only RBC magnesium shows intracellular stores accurately.

Creatine Monohydrate5g daily. Over five hundred human trials. No kidney changes at this dose in healthy adults. The creatinine rise is metabolic, not structural — GFR and cystatin C remain unchanged.

Vitamin D3 + K25,000 IU D3 + 100mcg K2-MK7 daily. Most men over forty are deficient. The K2 directs calcium toward bones and away from arterial walls — never take D3 at this dose without it.

Omega-33g EPA+DHA daily. Check the EPA+DHA total on the label, not the "fish oil" total. They are different numbers. Most products are significantly underdosed.

Zinc15mg with food. Rate-limiting factor for testosterone synthesis. Deficiency is common in men who sweat regularly. RBC zinc is more accurate than serum zinc.

What I dropped

Proprietary pre-workout blends. Mass-market protein powders. Several testosterone support products — no measurable effect on LH, free T, or SHBG across two ninety-day cycles. The evidence is limited on most of what is marketed to men. I try to say that clearly.

Not medical advice. FDA has not evaluated these statements. Products are not intended to diagnose, treat, cure, or prevent any disease. Some links may earn a commission.

THE PROTOCOL
Magnesium Glycinate 400mg — rMSSD moved in three weeks. Deficient for years without knowing it.
Creatine Monohydrate 5g — six years continuous. No kidney changes. Non-negotiable.
Vitamin D3 5,000 IU — twenty-four to 67 ng/mL in six months.
Omega-3 3g — index doubled.
Zinc 15mg — rate-limiting for testosterone.
The variable nobody tested: SHBG. My free testosterone was low even when total T looked fine. Fix the binding protein first. Then build the stack.
