Abstract

Pharmaceuticals and banned substances have been detected in hundreds of purportedly natural supplements. Recently, several athletes have been disqualified from competition after testing positive for the methamphetamine analog N,α-diethyl-phenylethylamine (N,α-DEPEA). Athletes have claimed they unknowingly consumed the banned stimulant in workout supplements. Three samples from different lot numbers of Craze, a workout supplement, were analyzed to detect the presence and concentration of N,α-DEPEA. Two labs independently identified N,α-DEPEA in the supplement using ultra high performance liquid chromatography (UHPLC) coupled to an LTQ Orbitrap XL mass spectrometer and UHPLC-quadruple-time-of-flight mass (Q-TOF) spectrometer, respectively. The identity of N,α-DEPEA was confirmed using nuclear magnetic resonance and reference standards. Manufacturer recommended servings were estimated to provide 21 to 35 mg of N,α-DEPEA. N,α-DEPEA has never been studied in humans. N,α-DEPEA is a methamphetamine analog; however, its stimulant, addictive and other adverse effects in humans are entirely unknown. Regulatory agencies should act expeditiously to warn consumers and remove N,α-DEPEA from all dietary supplements. Copyright © 2013 John Wiley & Sons, Ltd.

Attention Score in Context

This research output has an Altmetric Attention Score of 345. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 June 2019.
All research outputs
#32,049
of 13,372,528 outputs
Outputs from Drug Testing and Analysis
#5
of 814 outputs
Outputs of similar age
#390
of 166,100 outputs
Outputs of similar age from Drug Testing and Analysis
#1
of 14 outputs
Altmetric has tracked 13,372,528 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 814 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.2. This one has done particularly well, scoring higher than 99% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 166,100 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 92% of its contemporaries.
