So disturbingly bad is the quality of the steroids on the Dutch black market
The quality of the anabolic steroids on the black market is so bad that users hardly know which steroids they are injecting. Even if you have a hotline with William Llewellyn, [] with such crap, effective cycles are practically impossible. What good is advanced steroids knowledge if you can't trust the labels of the products on the black market?


We base the above paragraph on data published by the Doping Authority Netherlands on the EigenKracht website. The Doping Authority had several dozen preparations from Dutch users analyzed by a laboratory, and concluded to begin with that things were grosso modo severely underdosed.The average preparation on the Dutch black market contains only 55 percent of the number of milligrams of steroid on the label.
Remarkable was the total absence of mesterolone in the tested Proviron products. If you buy Proviron on the Dutch market, keep in mind that there may no active substances in the bloody thing at all. Or maybe they contain a little tamoxifen.

Wrong steroids
In almost all products, the lab found steroids other than those stated on the label. For example, the laboratory analyzed an ampoule that, according to the manufacturer, should contain 100 milligrams of methenolone.

However, this anabolic steroid was nowhere to be seen. Instead, the lab found in the ampule 140 milligrams of boldenone undecylenate, 75 milligrams of testosterone enanthate, 65 milligrams of testosterone decanoate, 20 milligrams of testosterone propionate, 5 milligrams of trenbolone nantate, plus some small amounts of anabolic steroids.
Methenolone is a popular steroid with users who want to minimize the health impact of their drugs. The users of the tested preparation will probably have felt quite cheated.
This may also apply to users of some of the tested trenbolone, nandrolone and drostanolone preparations which, according to the lab, contain testosterone as the main active ingredient. Users often opt for these preparations because they do not want easily aromatizable anabolic steroids in their system.
The laboratory also looked at the presence of substances other than steroids in the preparations. Heavy metals, for example, or pesticides. Fortunately, there was no trace of these contaminants.
