Tracking growth hormone abuse in sport: a comparison of distinct isoform-based assays.

What Was Tested

Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this randomized controlled trial publication.

Detecting recombinant human growth hormone (rhGH) abuse in sport remains one of the major challenges in doping control.

The researchers have compared two different approaches to detect the hGH (human growth hormone) abuse.

Who Took Part

PubMed tags the participants as men only.

How the Study Was Run

The researchers set it up as a randomized and single-blind study.

Because people in this Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Only one side, usually the participants, was kept unaware of whether Exogenous HGH, sermorelin & older GHRPs (why they're passed over) was given.

What Was Measured

The first measures the concentrations of the 22 kDa hGH isoform (rec assay) and pituitary derived isoforms (pit assay) and a ratio rec/pit is obtained.

The second measures the concentrations of 22 and 20 kDa hGH isoforms and also a ratio 22/20 kDa is derived.

The subject headings attached to it are Antibodies, Monoclonal, Doping in Sports, Human Growth Hormone, Immunoassay, Protein Isoforms, Recombinant Proteins and Substance Abuse Detection.

What This Means in Plain Language

The paper is a randomized and single-blind study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over).

The publication is from 2012 (Analytica chimica acta), a journal based in Netherlands.
