Well, we are about the same size, so I don't think you need my advice. . . But I do something like hst with aas, but a 2 day split to give more old-school volume. But I believe in maintaining a frequent stimulus. I do like 2 sets of 3 exercises for each body part I'm working. Its hst, but I split the full body in half, since the factors leading to hst (satellite cells, igf, etc) are mostly local, so the 48 hours is local. GH and test are factors in trad hst, but if your test level is artificially 9 to 10 times high all day, there are no peaks and troughs that are meaningful to "catch". I like it. And interestingly enough, its arnolds old olympia routine, chest/back am day 1 , legs am day 2 , shoulders/arms pm day 2, repeat . . . As hst says, you start to realize why old routines from the past worked or didn't . . . I will tell you this, I hit a plateau even with aas and hard training, and since i hit the first week of 5s with this hst, I have hypertrophied and my weight is up 10 lbs so far with less aas than before (just 400deca ew and 20 dbol ed)
