I posted this over in the paid community, but want to make sure everyone over here understands this! If you've ever used AOD, ARA, or a few others, you may have noticed gelling or clumping. There are a few peptides where you may need a solvent other than BAC in order to get them to reconstitute properly. These liquids are NOT interchangeable with each other. They will need one or the other. Acetic Acid: This has a LOWER pH number. The pH of the solution is around 2.75-3. Compounds that may need this: AOD-9604 (almost always), HGH Frag 176-191 (this is basically AOD by the way), Kisspeptin (sometimes, not always). Tesamorelin, CJC-1295, Sermorelin should NOT need this if you're using Hospira branded BAC water. Phosphate Buffered Saline or Sodium Bicarbonate Solution: These have a HIGHER pH number. Depending on which one, the pH is around 7-8. Compounds that may need this: ARA-290 (almost always), Thymosin Alpha-1 (sometimes). If you use the reconstitution cheat sheets, I tell you the appropriate solutions to use. I have a vendor working on getting the sodium bicarbonate solution in stock currently. I feel like it's important for you to understand the pH differences to understand that you can't use AA for a PBS-requiring compound and vice versa or it will take the pH in the wrong direction and probably make things worse.
