Early or partial results. Treat as a signal, not a conclusion.
A forensic DNA analysis of a commercial dietary supplement (Purtier Placenta) revealed that the primary ingredient was Rusa unicolor/timorensis rather than the advertised red deer (Cervus elaphus), with minor admixture of fallow deer (Dama dama). This finding supports regulatory concern about product misrepresentation but does not evaluate safety or efficacy.
Forensic species identification study using DNA barcoding and sequencing. Capsule contents from Purtier Placenta Live Stem Cell Therapy (6th Edition), a dietary supplement claimed to contain deer placenta stem cells and marketed to patients in the Czech Republic.. Intervention: DNA barcoding and species-specific Sanger sequencing of capsule contents.. Compared with: Reference sequences for seven species; declared ingredient (red deer, Cervus elaphus) per official marketing.. Product analysed; regulatory warnings issued by authorities in the United Arab Emirates, the Philippines, and Singapore..
DNA from 6th Edition capsule was primarily Rusa unicolor/timorensis, with minor components of Dama dama and Cervus elaphus Main component confirmed to be of deer origin despite species mismatch with marketing claims No evidence of claimed active ingredients or clinical trial support found in public registries
No clinical efficacy data, safety data, or mechanistic evaluation provided
This study does not evaluate clinical safety or efficacy. It documents species mislabelling in a product marketed with unsubstantiated disease claims; clinicians should be aware that regulatory warnings have been issued by authorities in the UAE, Philippines, and Singapore regarding misleading claims.

Purtier Placenta Live Stem Cell Therapy is a food supplement by Riway Singapore Pte. Ltd., claimed to contain living deer placenta stem cells together with 11 other active ingredients. It is also promoted as maintaining health and youthfulness and as being supported by numerous patents and research trials. Individual ingredients are accompanied by many other statements implying that Purtier Placenta can alleviate or cure diseases such as diabetes, cancer, and neurodegenerative diseases. However, none of these claims is traceable in clinical trial registries, and the mechanism allowing stem cells to be alive in the capsule and be effectively delivered to the body via the digestive tract does not seem plausible. Consequently, authorities in the United Arab Emirates, the Philippines, and Singapore have issued public warnings or imposed penalties in relation to misleading claims. Nevertheless, the product has gained popularity among Czech oncological patients, who perceive it as a magic cure. This paper describes a three-stage testing process designed to verify the species origin of the declared main ingredient. Using barcoding primer mixes, melting analysis, and Sanger sequencing with species-specific primers against seven reference species, we tested whether the capsule content corresponded to the red deer (Cervus elaphus) depicted on the official website (https://www.officialpurtier.com). Our analysis identified that DNA extracted from the 6th Edition capsule was primarily Rusa unicolor/timorensis, with minor components of Dama dama and Cervus elaphus. Although the main component was confirmed to be of deer origin, the lack of specific information and the wording of the marketing materials may be misleading.
