GRN Labs Vascular Intelligence

Your vascular age is a number
your annual physical never gave you.

Most men at this point have the data. Nobody has told them what to do with it. The protocol maps exactly what to change first, built from your specific results, including the markers behind blood pressure and morning erections. At 90 days, you re-test. That number either moved or it didn't.

Because I already have the number. The 90-day re-test will tell me if it moved.

The protocol starts from your calculator inputs. Lab work, when you're ready, makes it more precise.

The checkup that keeps telling you everything's fine has a design problem.

01
You came here from the calculator with a number.
And you exercise, watch your diet, plus you have a blood pressure cuff at home to know what the trend is. You may have even already tried a health platform that gave you data you couldn't act on.
02
The problem is that data without a specific plan and feedback loop is just another thing to try.

Trackers gave you panels and a generic recommendation list.

Your doctor gave you a pamphlet and a follow-up in six months.

Reddit gave you 40 different opinions on which magnesium to take.

What none of them gave you: a protocol built for your specific combination of markers and current lifestyle. None of them re-tested you to show whether anything moved. GRN Labs was built to close those gaps.

03
You have the number. The next question is whether the plan is actually specific to you.

A recommendation list is general. A protocol is built from your specific combination of factors. GRN Labs assigns you to one of eight clusters based on your 15-factor pattern, then delivers the supplement forms, the weekly focus priority, and the re-test cadence that fit your cluster specifically.

Fifteen factors evaluated.

Eight biological clusters.

One protocol mapped to yours.

Re-tested at 90 days.

What this gives you that your physical does not.

How It Works

The loop that moves the number.

Every data point you add makes the protocol more precise, so what you're doing today is informed by what actually worked last month.

Step 01

Your Score

Your calculator result becomes the baseline. Every factor that drove your number is visible, ranked by impact, and graded against the research-backed optimal range.

Your Vascular Score
ApoB Elevated
hs-CRP Optimal
Homocysteine Elevated
Vitamin D Low
Step 02

Your Protocol

Four domains, specific to your markers. Each recommendation links to the research behind it. As you add data, the protocol refines to reflect what's actually changing.

Protocol — Week 1
Nutrition 3 actions
Lifestyle 2 actions
Exercise 2 actions
Supplements 1 action
Step 03

Your Re-Test

When you order a follow-up panel, the protocol maps what moved and adjusts accordingly. Each cycle narrows the gap between where your vascular health is and where it should be.

ApoB Improved
hs-CRP Stable
Homocysteine Improved

The Protocol

Built from your markers. Updated as data comes in.

Most health advice applies to everyone. This applies to you. The protocol maps the changes most likely to move your vascular age across four domains.

When you add new data, the protocol updates to reflect it.

The Feedback Loop

What moves at 90 days.

Most health changes happen too slowly to notice without a before and after. The re-test is that before and after.

Days 1–30

Baseline and first shifts

Protocol targets identified. First measurable changes to blood pressure and resting heart rate typically begin here for men who engage fully.

Days 30–60

Subjective signals shift

Energy steadier. Recovery faster. Sleep quality measurably different for most participants by week six.

Days 60–90

Measurable improvement

Research shows measurable vascular marker improvement at 90 days with consistent targeted intervention. Re-test reveals what moved.

“

My vascular age came back at 61. I am 49. That number was uncomfortable to hold. I followed the protocol for 90 days and retook the assessment. It showed 55. I had never had a before and an after before. I had only had numbers I could not do anything with. The 90-day re-test changed that. I have two kids. Being present for the next 30 years at full capacity is not a metaphor for me.

I came here from a Peter Attia episode. I thought I knew what my cardiovascular risk looked like. My vascular age came back at 59. I'm 46. The 90-day re-test showed 54. That's five years of arterial age in one protocol cycle.

Questions

Good ones, answered.

What if my standard bloodwork is already normal?

Normal on a standard lipid panel isn't the same as optimal vascular age. GRN Labs assesses endothelial function markers, ADMA accumulation, and glycocalyx-relevant factors that a standard metabolic panel doesn't include. Most men with normal LDL-C and blood pressure in the acceptable range can still carry vascular ages meaningfully older than their chronological age because these upstream mechanisms are not measured in routine screenings.

How is this different from Googling supplement stacks?

A Google search returns population-level research. GRN Labs assigns you to one of eight biological clusters based on your specific 15-factor score, then delivers the forms, doses, and timing relevant to your cluster pattern. The 90-day re-test then tells you whether that specific protocol moved your specific markers. That feedback loop doesn't exist in any search result.

Will this work if I'm already on blood pressure medication?

Yes. GRN Labs works alongside existing care, not instead of it. Many men using GRN Labs are also managing blood pressure with medication. The 90-day re-test data is designed to be shared with your physician, giving you more specific information for that conversation than a routine follow-up appointment typically provides.

What happens after 90 days?

You retake the 15-factor assessment. Your vascular age score updates based on your current markers. If your cluster assignment warrants an adjustment to the protocol, the protocol updates. Your subscription continues with the updated plan and a new 90-day re-test cycle.

What if my vascular age does not improve at 90 days?

The re-test tells you what changed and what did not. If your vascular age didn't move, the data shows which specific factors held flat. That information has value: it narrows the protocol and gives your next 90-day cycle a more precise target. GRN Labs does not promise a specific number. It promises a feedback loop that no other platform provides.

Is GRN Labs a substitute for seeing my doctor?

No. GRN Labs is a vascular health assessment and protocol platform. It is not a medical service and does not provide diagnoses. It generates data that is designed to complement your medical care and support more specific conversations with your physician.

How does the cluster assignment work?

Your 15-factor score places you into one of eight vascular biology profiles based on the pattern and severity of your marker combination. Each cluster has a corresponding protocol: specific supplement forms and doses, a weekly focus priority, and blood pressure logging cadence. The cluster is not a diagnosis. It's a protocol architecture.

What is the cancellation policy?

You can cancel your subscription at any time before the next billing cycle. There are no contracts and no long-term commitments.
