Bottom Line: Store Dry Longer, Mixed Shorter The simplest BPC-157 storage rule is this: dry powder is for longer storage, mixed solution is for short refrigerated use
The Shared Backbone: BPC-157 and TB-500 Because all three blends contain both BPC-157 and TB-500, understanding this pair is the single most useful thing a reader can do
