You never know. I still think it's very unlikely however, all it takes is one dejected player in the squad to leak the info and the whole operation gets blown. This could mean they either are given PEDs without being told which is an extremely messy lawsuit considering every new designer performance enhancer isn't FDA approved. If penrith were to be using peptides it would have to be a few players on their own merit, it would be the only way that information would never get leaked, even then if nrl follows protocols they are supposed to they would get popped for it and be aware. It's a big conspiracy to suggest that nrl simply detect PEDs in certain players and turn a blind eye, a risky game for not much reward. Hate to admit it but the penrith dynasty is most likely just from good coaching and discipline. Sharks were caught of peptide use when it was new and they believed they could get away with it, they got busted most likely because rumors circulated and more strict testing was implemented afterwards. I think with how advanced they are in detecting things these days you will most likely never get a repeat of that situation unless a new designer drug is released that is completely undetected in blood test results (doesn't show weird levels comparable to PED usage) and if this drug did exist I doubt NRL would be the first to get a hold of it.
