I've just found a news report in Autosport about this sponsor, but it's a bit muddled. (Autosport 2 Jan 1975 p3). It refers to Laffite having sponsorship from "the Swiss drugs company Caffina, who are based in Lucerne". It then goes on to suggest that H7 and "Ambrosium" [sic] are two different but very similar products "which supposedly rejuvenates those over 40 years of age". ....
An interesting case and a sobering thought on how good it was back in 19…. Possibly his sponsorship money was welcome despite his past (if at all known to the fund receivers). In fact, Dr. Bruno Cassina was convicted for drug trafficking as early as 1962. He had been receiving parcels with cocaine in his Lucerne pharmacy and sold it on. For that he got a one year (!) sentence and a 1000 Franc fine for drug trafficking. He had been framed as a customer tipped him off after finding out he was cutting the real stuff.
In 1971 he was also linked to the death of a woman who had overdosed to morphine. He had been supplying her since 1969. News that was in the Swiss press.
In 1976 he was forced to, beside Ambrozium also withdraw Gerovita and Aslavital from the Swiss market. Now Gerovita seems to have a long history in the world of potions and snake oils. In the 80/90’s it was sold (also through the net) by Gero Vita International. A company of a person called Braswell who started to sell in the late seventies, early eighties products to cure baldness, delay the aging process, cause weight loss, etc.
Now one of the products he sold was called Gero-Vita GH3, supposedly an anti-aging formula developed further on a product from Europe called Gerovital H3. Here is your H3.
In 1995, the FDA banned the importation of all of Gero Vita's products marketed with claims that they can prevent or treat disease. All prison time and financial penalties could not stop the guy, even after his death. And still Gerovital and Aslavital are available on the net.
Another link with racing. Richard Petty (with two other famous sportsmen) filed suit in a Californian federal court against Braswell and Gero Vita for misusing their names in advertisements for Prostata in 1997 claiming they suffered prostate problems.
