2. UK Anti-Doping (UKAD) has announced former Leigh
and Wales hooker Sean Penkywicz has been banned for
two years after he tested positive for a growth hormone
releasing peptide.
The 33-year-old tested positive for GHRP-6 but denied
taking the substance. However, Penkywicz accepted the
doping verdict and had his contract terminated by the
Centurions. His sample was initially tested by the Drug
Control Centre at King's College, London and no
prohibited substances were found. UK Anti-Doping
instructed the laboratory on January 27 to reexamine the
same sample specifically for Growth Hormone Releasing
Factors. The sample was found to contain Hormone
Releasing Peptide-6 (GHRP-6).

3. Growth Hormone Releasing Factors are classified under section
S2 of the World Anti-Doping Agency's (WADA) Prohibited List.
This is the second finding of its kind in the United Kingdom for
GHRP-6 that is commonly used by bodybuilders. Sean has been
banned from all sport from April 9, 2015 to April 8, 2017.
In 2007, Penkywicz played for Wales in World Cup qualifiers
against Scotland and Lebanon and won his last cap against
England a year later. Penkywicz was in the Leigh team that won
the Championship Grand Final at Headingley last October but
has not played this season due to a knee injury. In 2005, he was
suspended for two years after he tested positive for Stanozolol
(Winstrol) after his sample tested positive for the drug
following an out-of-competition test on December 5, 2014.
