Lately I’ve been second-guessing myself every time I mix a new peptide vial, because even though the steps seem straightforward, I still get this weird feeling that I’m either shaking it too much or adding the water at the wrong angle. A couple of times the powder dissolved unevenly, and once I even got tiny bubbles that didn’t go away for hours. I’m wondering if others run into similar issues and what the most common “rookie mistakes” actually are, since half of the guides online contradict each other.
