Yeah personally I just don't find it fun. Just as glp1s are a shortcut to lose weight I would rather have the convenience of not mixing my nad. More power to whoever enjoys it.I don't know, friend. For me, the time spent researching and prepping the materials is all part of the fun of it. The time and money are investments in my health, and that's invaluable.
It's all in your perspective. This is more of a fun hobby than something I view as a chore.
Also, and forgive me if I'm wrong, but don't group buys pool resources to purchase large quantities from... Chinese manufacturers? Again, someone please correct me if I'm mistaken. I would just hate for some unsuspecting soul to pin some NAD+ without checking the pH and suffering the acidic, fiery hell that might follow, along with the potential tissue damage.
The only way for you to get exactly what you want without any sort of time and labor spent is to go legit. There is no easy way out on this side of things. If you're not willing to research, then what is the point of going the research route?
As far as the group buy goes for nad I've ever only seen it buffered because you can buy it every day unbuffered. The organizer will usually disclose whether it's buffered or not.
