Frequently asked questions

PCC1™ is the finished dietary-supplement formula sold on this site. It combines procyanidin C1, procyanidin B2 and epicatechin in a phospholipid-complex formulation. It is not a medicine and is not intended to diagnose, treat, cure or prevent disease.

Published research on procyanidin C1 includes a Nature Metabolism preclinical study in cell and mouse models of cellular senescence. PCC1™ is built around that compound, with procyanidin B2 and epicatechin, in a finished monthly formula. Explore the science.

It describes how the ingredients are paired with phospholipids in a phytosome-style delivery format. In our measurements, that approach achieves about 5.7× better bioavailability than standard grape-seed extract.

Each box contains 3 sachets, and each sachet contains 3 capsules. One box provides one complete 30-day monthly cycle.

Take 1 sachet (3 capsules) daily for 3 consecutive days, followed by 27 days off. This is one 30-day monthly cycle.

Senolytics are typically studied as short, spaced pulses rather than daily doses. PCC1™ follows that idea: three days on, then twenty-seven days of rest — one complete 30-day cycle per box.

We cannot assess individual interactions. Ask an appropriate healthcare professional before use if you take medication or other supplements, have a medical condition, are pregnant or nursing, or are under 18.

We offer free shipping only to the destinations currently supported at checkout. Choosing a site language does not establish delivery eligibility; the delivery address entered at checkout is authoritative. See the current destination list and shipping policy.

We send tracking information by email after dispatch. Delivery time varies by destination, carrier and customs, so an estimate is not a guaranteed delivery date.

Eligible purchases may be reviewed under the published guarantee when you contact us within 90 days of delivery and provide the requested order details. We generally do not require the product to be sent back. The policy does not limit mandatory consumer rights. Read the full returns policy.

The price, billing interval and quantity are shown before payment. Monthly plans bill for 1 box, quarterly plans bill for 3 boxes, and annual plans bill once for 12 boxes planned as four quarterly shipments of 3 boxes. A subscription renews at the selected interval until cancelled.

Use the contact form before your next billing date. Cancellation applies to future renewals once confirmed and does not reverse an order already processed, except where the returns policy or applicable law requires otherwise.

The published reports document the named samples, batches, methods, analytes and results — including heavy metals, microbiology, residual solvents and procyanidin C1 content. Read the original laboratory reports.

PCC1™ is manufactured at a GMP-certified facility. GMP covers manufacturing controls for how the product is made.
