Benefits found that match human patients. Just when the hell is someone going to write up a stroke protocol on this? I'm guessing never since stroke patients have no say in anything about the stroke medical world. We are just pitiable objects to bring in donations to our fucking failures of stroke associations.

Abstract
We previously demonstrated that the administration of growth hormone (GH) immediately after severe motor cortex injury, in rats, followed by rehabilitation, improved the functionality of the affected limb and re-expressed nestin in the undamaged contralateral motor cortex.
Here, we analyze whether positive GH effects are restricted to a time window after the cortical injury and if this is dependent on the re-expression of nestin and actin.
Injured animals were treated with GH (0.15 mg/kg/day) or vehicle, at days 7, 14 and 35 after cortical ablation, and rehabilitation was applied at short- and long-term after the lesion. On completion of the long-term rehabilitation, animals were sacrificed and nestin and actin were analyzed by immunoblotting in the undamaged contralateral motor cortex.
Giving GH at days 7 or 35 after the lesion, but not 14 days after it, led to a remarkable improvement in the functionality of the affected paw. The abundance of contralateral nestin and actin re-expression was clearly higher in GH-treated animals; probably because compensatory brain plasticity was established.
GH and immediate rehabilitation are key elements for repairing brain injuries, with the exception of a critical time period; that is, when the GH treatment starts 14 days after the lesion. Our data also indicate that there is not a clear plateau in the recovery from a brain injury. This agrees with our data in human patients.
