NRTC-103 is a U.S.-manufactured version of "Neurotec"—the multi-herbal supplement that uniquely combines dried extracts from Rosa canina, Urtica dioica, and Tanacetum vulgare in oral capsule form and which has been studied in placebo-controlled clinical trials and published about in peer-reviewed scientific journals.

NRTC-103™ is a dietary supplement formulated to match the original Neurotec herbal capsules that uniquely combine Rosa canina, Urtica dioica, and Tanacetum vulgare dried extracts. NRTC-103 is a replication of the same Neurotec herbal formulation that has been studied in various placebo-controlled clinical trials and discussed in published peer-reviewed scientific journal articles.

However, beyond just matching same ingredients listed on the Neurotec label, in the exact same amounts, NRTC-103 is considered interchangeable and comparable to Neurotec and the body of research behind it. Because it is standardized to meet the exact same chemical properties and identifying characteristics according to the original Neurotec manufacturer's specifications. In other words, it is a "clone" of Neurotec according to every meaningful and measurable feature.

Even the capsules and blended contents are indistinguishable from the original Neurotec capsules. Another obvious difference at the surface is of course the name. NRTC-103 instead of Neurotec. And the manufacturer, since NRTC-103 is made in the United States by TG Labs Inc.

Until recently, the original Neurotec had no substitutes or replicated versions available and this was a problem because Neurotec was not available outside of clinical trials or more broadly outside of its country of origin, Iran. And because of strict export restrictions, there was no way to order or legally access Neurotec if you lived in the United States or to North America, or anywhere in Europe, or anywhere outside of Iran. But research into this herbal combination and the strength of the findings and science alone, were enough to drive interest outside of the original country and eventually this inspired two companies in the United States to collaborate in developing a version of Neurotec available at home.

What happened was, in late 2024, an FDA-registered laboratory and manufacturing facility in Colorado (TG Labs Inc) finally began producing a domestic version of the original Neurotec herbal capsules. The decision was based on a growing interest from U.S. consumers to try as a dietary supplement the unique herbal formulation of Neurotec. Initial demand was limited, but strong among those who knew about the research papers that talked about Neurotec and the specific herbal combination it offered.

Today, that multi-herbal product is more widely sold as a non-official replication of Neurotec: NRTC-103.

NRTC-103 is sold as a U.S.-manufactured and domestically available version of Neurotec that is identical to what has been investigated in clinical trials and discussed and analyzed in various scientific papers.
