ya, you are being jacked. those are prohormones, now just as illegal as steroids. the effectiveness is much less than steroids due to delivery issues and then conversion to active product.
the first is actually the only compound worth considering. Biotest used to make an excellent version before the ban that solved the delivery issue. this product was active in its unconverted form.
the second, the mark macguire drug, is a shitty testosterone precursor that has high estrogen conversion thus side effects and no gains.
the third is a 4-hydroxylated 17aa nandrolone. there is little feedback with this compound. in theory the 4-OH group will prevent aromatization and perhaps progestone activation, though nandrolone has low aromatization to begin with. i would stick to anavar, just as illegal, but proven and backed by mounds of actual human data.
you would be much better off purchasing a vial of testosterone enanthate and some arimidex for a cycle. this is a proven, safe combination and relatively cheap, it will certainly cost less than what that douche is trying to sell to you if you are measuring potential gains oer dollar spent and you will have to put a lot less hormone into your body. the option remains to stack anavar with the test furthur increasing the effects of the cycle.
