He's better off saving his stash until he can get a hold of some Test Prop (enough to run 75-100mg/day for the duration of the cycle), an AI, and some syringes if he wants to get near his goals. Usually, uneducated noobs are the only ones who run oral-only cycles.
If he is absolutely set on running solo OT, then I'd suggest maybe extending the cycle a couple weeks and/or upping the dose. A lot of people increase the dose until they experience uncomfortable sides (back pumps, headaches, achy joints, etc) and then drop back down a little.
I think the half-life of Turinabol is on the longer side as far as orals are concerned, but spreading out dosages couldn't hurt. I'd also be sure to pop a good amount of the daily dose right before hitting the gym.
