I've not seen any sites close down
One has changed it's domain name from .com.au
You're not trading within Australia if you do not have a .au domain name. The Australian government holds no jurisdiction over .com TLD sites, only .au
There is also only one peptide that has been legislated against. You can't blanket ban all peptides - only ones that have been proven to be growth hormone releasing peptides. Thankfully, many don't have legitimate studies done on them. Synthetic IGF for example holds no evidence whatsoever that it has physiological effects on the body. Studies done on animals are also not enough to legislate. The Government is actually very reluctant to ban things that are not killing people due to the amount of research that would have to go into it first. DMAA killed a kid so it was easy to ban. 4-mmc killed a kid so it was banned. Steroids have major health risks. HGH frag will never kill anyone, there is no evidence on humans that links it to increased GH levels in the body.
The peptide industry is here to stay, it's incredibly profitable- especially in Australia and the government has better things to do once this scandal is blown over like banning things that people actually use and are of risk to the human body
