I personally do not believe it has that great if any localized spot reduction properties, as I have tried it few times, however, this shit is potent!!! Used Keytech Helios at 40 MCG and it feels like 120mcgs of oral clen.
The only bad thing with the Helios is that you have to injected yourself everyday, so your skin become tender. Otherwise, I am seeing better results with the Helios then the Clen.
