After graduating, Guggenheim joined Burgelstein's private laboratory in Basel. He worked there from late 1986 to 1988 on stress physiology and catecholamine research. His work included cardiovascular monitoring, blood collection, blood-gas measurements and the processing of plasma samples for adrenaline and noradrenaline analysis. Burgelstein was already conducting unauthorized experiments on adult psychiatric patients obtained through medical contacts, and Guggenheim assisted with restraint and physiological monitoring during these procedures.

Burgelstein transferred his work to the Glöbbery-controlled [[Rheintor Medical Institute]] in 1988. Guggenheim became a Laboratory Physiologist and was promoted to Deputy Laboratory Chief in 1989. He directed staff during experimental sessions and supervised physiological monitoring and sample processing while Burgelstein retained overall authority. The Rheintor Catecholamine Trials later involved captive adults and children. Surviving records identified 312 victims, of whom 117 died during the experiments or from their effects.<ref name="rheintor-trials"/>

Guggenheim took part in blood-extraction experiments on captive children and recorded cardiovascular changes during the procedures. In the later Rheintor period he sometimes consumed blood taken from captives before it was processed, leading staff to call him '''The Slurper'''. He formally left the Deputy Laboratory Chief position when he moved to Israel in 1992, but Burgelstein kept him on a restricted internal payroll as an external scientific adviser. Guggenheim reviewed Rheintor data from Israel and returned to Basel several times a year for selected experiments and changes to the institute's protocols.
