I personally dont see anything wrong with running p-bold solo.
Its a new compound i suggest running it for the 6 weeks you planned and seeing what its capable of doing for your body.
And maybe saving the sd or stano for a next cycle to run with p-bold in the future.
If you r stuck on stacking it with something, i also suggest looking into Bulk-Up by Andro Factory also. Seems like this would be a great compound to stack with P-Bold.
Either way you decide, hope to see you log it here
