I love primo S!!But keep in mind that I like hardness-drugs(winny,oxa) and not the mass ones(test,dbol,drol).
Primo S is fine,but expensive.
I've used 125mg(5tabs/ed)for 3weeks beacuse I couldn't get some more that time.
I loved the results in hardness.No size gained though,but my muscles were too beutyfull!!
