Qenph sources: manufacturer, health authorities and studies
Find out how Qenph selects and ranks sources to review PhenQ, PhenQ PM, their ingredients, precautions and commercial claims.
A source does not carry the same weight for every question
The manufacturer’s official page is generally the best source for the stated composition, format or directions for use. It is not, however, an independent source for judging the effectiveness of its own claims. Conversely, a meta-analysis may be excellent for evaluating an ingredient but may not know the current commercial formula.
Manufacturer sources
PhenQ and PhenQ PM are used to verify the current product presentation, listed ingredients and commercial instructions. Performance claims are identified as brand statements and compared with external sources.
Health authorities and institutional bodies
Qenph gives priority to sources such as the NIH Office of Dietary Supplements, Anses and EFSA when they have published a relevant review. These sources are especially useful for safety, interactions, intake levels and the overall state of evidence.
Scientific literature
Systematic reviews and meta-analyses are prioritised when available. Individual randomised trials are then used to understand a dose, population or specific outcome. A single study is not presented as certainty when it contradicts or goes beyond the rest of the literature.
Commercial sources and testimonials
Customer reviews can provide information about reported experience, taste, delivery or perceived tolerance. They cannot establish clinical effectiveness. Weight loss reported in a testimonial may be influenced by diet, activity, starting weight and many other factors.
