To further determine the proportions of fake AAS found on the black market, we conducted a systematic literature review and meta-analysis of analytical test results for those substances within the published literature. The very wide range in proportions of counterfeit or substandard black market AAS puts the user in a situation of unpredictable uncertainty. This also may have led either to over or under estimation of certain proportions of the estimates of "substandard" or "counterfeit" anabolic androgenic steroids and their subclassifications and sub-analyses. Rather than caused by study design issues, the differing proportions of counterfeit or substandard AAS reflect the selection of the tested AAS samples, with real differences in the quality of AAS found on the black market. We searched PubMed/Medline, Embase and Google Scholar for studies published before March 29, 2022 that analyzed the quality and quantity of AAS to determine the proportions of substandard and counterfeit products found on the black market. With this systematic review and meta-analysis on black-market AAS, we have demonstrated that substantial mean proportions may be of substandard quality or counterfeit. Funnel plot for counterfeit AAS (left), funnel plot for substandard AAS (right). In some studies, the contained active ingredients in "under-concentrated" preparations was much lower than 50% of that indicated (e.g. 0.5–1.5% , 9% or 16% ) if quantitative data was available. Firstly, defined ranges of declared labels could vary massively between articles, had a quantitative analysis been performed, with defined ranges between 50–200% , 80–130% , 80–120% or 90–110% . Furthermore, we assessed the different analytical methods used to determine the quality and quantity of AAS on the black market. We used a subclassification of "counterfeit" substances to comprise "adulterated", "substituted" and "inert"; and "substandard" substances to comprise "over- and under- concentrated" (Table 3). • to increase the homogeneity, article with mixed samples (e.g., if the analysis includes different classes of IPED) in which data on AAS are The shift from pharmacies to deregulated underground online sites and clandestine underground laboratories occurred after the United States enacted the Anabolic Steroid Control Act in the 1990s. AAS were the most dominant group within all analyzed products, and they were almost exclusively analyzed within the WADA class S1. Some authors assessed visual inspection of packaging and detection of counterfeiting rate with contradicting results.
