## Questions

### Does HEALTHYLIFE10 still work?

Yes. It was cart-tested on October 9, 2026 and took $9.00 CAD off a $90.00 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.

### How can I tell if a peptide company is legitimate?

Weight the things you can check over the things that impress. Stated shipping routes confirmed by your own tracking, testing you can verify on a laboratory's own domain, batch codes that match your vial, and policies specific enough to be breached. Site design and certificate styling prove nothing.

### What should I ask a vendor before ordering?

Ask which batch will ship and request the report for that specific batch. A seller testing per production run can answer immediately because the document exists. One reusing a single certificate will answer a more general question instead, and that substitution is the signal.

### Is unusually low pricing a red flag?

It is information worth following up. Independent testing, proper handling and per-batch documentation cost money, so a seller well below the market has either found a genuine efficiency or stopped paying for one of them.
