Testosterone is number 1 in the Swiss Steroids Top 100
Researchers at the Antidoping Switzerland Foundation have published in Forensic Science International the amount of steroids and other bodybuilding drugs that the Swiss customs confiscated in the period 2013-2014. There were 960 consignments and a total of 1,825 products. We took the liberty of converting the tables in the article into figures.
The classic anabolic steroids were the most important group of substances. Almost 25 percent of all products confiscated contained testosterone. Testosterone, methandienone (the active substance in Dianabol), nandrolone, trenbolone, stanozolol and boldenone account together for 52.6 percent of all products confiscated.
The Swiss customs also found SARMs and designer steroids, but only small amounts. These substances are either not used much or they slip more easily through the net. The same can be said of newer substances such as ACE-031, Aicar and GW-1516, as the figure below shows.
The figure also shows that clomiphene and tamoxifen are probably still the most used anti-oestrogens in the Swiss steroids scene. Clomiphene and tamoxifen together accounted for almost 8 percent of all confiscated products.
The peptide hormones that the customs found were also mainly the classic ones such as growth hormone, hCG and IGF-1. The Swiss also intercepted some research chemicals, but only small amounts. So either the bodybuilders in Switzerland stick to known substances or research chemicals still enter the country relatively easily.
