I've been on these PP blue tops for about a week now and I am very impressed! Keep in mind I've been on GH straight since early Nov 06. No welts or problems at the injection spot and I am very prone to those issues with any 192aa GH, so that must mean that these are just what the label claims..191
If you see them on any lists, BUY THEM! I think I just may be able to afford staying on GH forever now.
