If you can stand the pains, you'll make the gains.
It is works well, as well as being cheap. I don't know about other suspension but RWR Susp. is fairly granular (worse than their Stanozol) so you need to mix it with either B12 or maybe an oilbased inj. to help with getting it in without the pin getting blocked.
You might ne left with a lump of sorts but it goes away after a while. Makes inj. in the same place a pain in the arse (litteraly)
