Only ever bought a single kit so far. The bloating side didn't sit well with me, so I quit after five days, actually happened twice in a row like that. Put my second mixed vial straight into the freezer. Working through vial three currently, which has spent just past a week chilling. Clarity held up perfectly across all of them the whole time refrigerated.
Taking it before bed left me with wild, vivid dreams, actually enjoyed that part, but then I'd be staring at the ceiling wide awake around three-thirty every night without fail. Moved the timing to fasted mornings instead, and honestly it's been a huge improvement. More energy, sharper focus, fingers crossed for better outcomes in my training too.
A delivery pen's on the way, planning to fill it with roughly two to three weeks of supply and store that in the fridge. Curious enough about the frozen batch that I'll probably thaw it out and see how it compares first.
Anyway, where I've landed for now is a moderate amount combined with a touch of a separate growth-hormone-releasing peptide taken each morning, kept cold.
