Now we're getting into a bit of opinion & surmise, but sure, I think 70 mg, +/-, is probably a close enough approximation for a sane initial dose, to assess Tren effects, efficacy/tolerability as a starting point, for the average or above average person in terms of AAS capacity/response. And what do ya know, it's right in line with what Negma came up with.
I don't like acetate for assessing Tren effects, this is my personal opinion. I'd just go with enanthate or hex. I think the at least alternate day pinning is already too much for someone new to trenbolone, it just reduces tolerability so much. I know I'll never go back to acetate, enanthate q.w. (1X/week) and boom, gtg.
