Our method
Every review answers the same seven questions.
A good decision needs the same facts every time. These are the questions we answer for every product, in the same order, so you can compare them side by side.

The seven questions
- Who makes it, and where does it ship from? We name the company on the brand's own terms and where it is registered.
- What's inside, and at what dose? We list every ingredient the brand publishes and say clearly when doses are not disclosed.
- What does the research say? We summarize published studies on each ingredient and link to them.
- What does it cost per day? We record every pack on the official store and work out the price per day.
- What do recent buyers say? We read the latest customer reviews, note what they praise and turn their most common problems into buying tips.
- How does the refund really work? We quote the guarantee as the brand writes it, including its conditions.
- Where do you get the original? We point to the official store and explain how to avoid copies.
Our sources
- The brand's own product page, order page and terms.
- Published research, mostly systematic reviews and meta-analyses found on PubMed.
- Prices and guarantees on the official store, recorded with the date we checked them.
- Recent customer reviews on independent platforms such as Trustpilot.
Keeping reviews current
We recheck prices, guarantees and availability every month and show the date of the last check at the top of each review. When something changes, we update the review and its date.
