Heres the deal. Without b/a water usuing sterile water the GH weakens after 3 days, its good up to around 8 days w/o the b/a but is much weaker at half strength at 8 days. With B/A 10-14 days the Gh will remain the same potantcy. the b/a has antibacterials in there thats why. Bacteria is what weakens the gh protein
