Mg for mg Test suspension is best, can hurt like hell but here is why it's the best.
It's the only one without an ester. The ester chains that are attached to all the other tests, weigh something and take up room. So there is less of the parent
steroid. the longer the chain, the less of the parent
steroid.
So the test that has no ester would in fact be the best.
Now for which one I like the best, I'd say test enanthate. Not as many shots per week. Especially when your also doing fina.
As it is, I already feel like a pincushion.
