Would you re-test mazdutide after sixteen weeks at room temperature, or accept the original certificate?

What I am working with: mazdutide · sixteen weeks · room temperature.

I would rather over-plan the first cycle and simplify later.

I am prepared to do the work if someone can tell me which work matters.

What is the minimum version of this that is still defensible?
