Is that the Gaspari Halodrol?
If it is I would say no PCT is neccesary because it contains no P/H's. I see the version they are selling in Aust is missing DHEA which is in the US version. As usual the most potent ingredient is taken out for the Aussie market.
P.H's can be of some benefit if taken correctly, but remember you can't get them legally in Australia and if you did you would require proper PCT with drugs like Nolva, Clomid and HCG which are not available without prescription.
I think i have been down this path before. LOL
