## Questions

### Does HEALTHYLIFE10 still work?

Yes. It was cart-tested on October 22, 2026 and took $20.00 CAD off a $200.00 CAD cart at growthguys.com — exactly 10%. This page is rebuilt from that test, so the date above is when it was last confirmed, not when it was written.

### Does 99% purity mean the vial holds 99% of the labelled dose?

No. Purity is an area percentage describing what proportion of the detected material was the target compound. How much material is in the vial is a separate content or mass test. Of the 240 published reports, 178 carry a purity percentage and 62 are identity or content tests.

### How many of the published reports fall below 98%?

Thirty-three of the 178 reports that carry a percentage come in under 98%, and they are published alongside the rest. The full range runs from 93.844% to 99.99%, with a median of 99.52%.

### A kit report shows a mass far below the labelled strength. Is the product underfilled?

Check the denominator before concluding anything. On the six HGH kits in this set the product name states the kit total while the report covers one vial, a ratio of about ten to one. Measured against a single vial's share, those six results fall between 97.2% and 109.4% of label.
