Why it's built for men

Three jobs, one daily stack.

Muscle, testosterone and metabolic health all move in the same direction with age — the wrong one. The Men's Vitality Stack is dosed to the ranges used in human trials to work against that.

Supports testosterone

Zinc contributes to the maintenance of normal testosterone concentrations in the blood — dosed within the EU-recommended range, nothing hidden in a blend.

Builds muscle & strength

Creatine monohydrate at the 3–5g daily intake shown to increase physical performance in successive bursts of short-term, high-intensity exercise.

Maintains lean mass

Whey protein to support muscle maintenance as part of a resistance-training routine, plus magnesium to support normal muscle function as the years add up.

The decline no one flags
8%/decade

Men lose roughly 3–8% of lean muscle mass per decade after 30 — faster again after 60. Testosterone declines gradually alongside it.

Getting older shouldn't mean giving up muscle.

Most men either ignore the slide or reach for a "T-booster" with a proprietary blend and no real evidence behind it.

The Men's Vitality Stack is the evidence-only alternative: nutrients research has actually measured, at the doses used in the trials, printed on the label.

What's inside

Every ingredient. Every dose. Disclosed.

No proprietary blends hiding sub-effective amounts. The core stack:

Zinc bisglycinate chelate15 mg
Creatine Monohydrate5 g
Whey Protein isolate25 g
Magnesium glycinate200 mg
How to use

Once a day. Every day.

01

Pick your stack

Start with the core four — zinc, creatine, whey and magnesium — or build around whichever you're already taking.

02

Keep it consistent

Testosterone and muscle-support nutrients work by staying topped up. A daily habit beats an occasional dose.

03

Give it a full cycle

Let it run across a full training block — creatine saturation and steady zinc intake both take a few weeks to show. Your 60-day guarantee covers you well past that.

Why we built Proco
"Most men's health supplements were proprietary blends and T-booster pixie dust. So we disclosed every dose, matched them to the human trials, and let the label do the talking. If the evidence isn't there, we don't stock it."
— Johnny Meagher, Founder
Questions

Straight answers.

Why not just take a "T-booster"?

Most T-booster blends don't disclose individual doses, so you can't tell if you're getting a meaningful amount of anything. We only stock ingredients with human-trial evidence, dosed to what those trials actually used, and printed on the label.

When will I notice a difference?

Creatine saturation and steady zinc and magnesium intake typically take a few weeks. It's a daily, cumulative thing, which is why the guarantee runs a full 60 days.

Are the doses actually meaningful?

Every ingredient is dosed to the range used in the human trials we reference — no proprietary blends, no sub-effective amounts. The exact dose is printed on the label.

Is it third-party tested?

Every batch is tested by an independent lab, and the certificate of analysis is available.

Can I cancel the subscription?
