An underground concoction with NO legitimate research to support it.
Yes, Mesotherapy and lipostabil DO have a history, and a number of articles can be found on these.
I did a search of PubMed, which has over 17 million articles from MedLine, as well as numerous other science publications from all over the world - NOTHING on helios. Then did a Google search on helios alone - NOTHING on the first 10 pages, after that I stopped scrolling. Finally did a Google search using the terms helios AND mesotherapy together. The only things that came up were from BB forums like Bodybuilding.com, and a place called AvantLabs, who look like they sell this stuff.
The article posted a few days back was taken down since there's NO credible research on this helios.
