My injection looks...off?

Just curious, why do they put "For Research Only" on these things if they're OK to use? Seems kinda sketch.

Un-reconstituted vials should be clear or slightly off-white - cloudiness or particulate before mixing warrants a supplier inquiry.

Injection Shop is worth bookmarking for needle supplies - consistent stock and the prices are reasonable.

The vacuum seal integrity check is the primary indicator for untampered product - a properly sealed vial will have visible resistance when the cap is first broken. Powder appearance with no discoloration, clumping, or unusual particulates is the secondary check before reconstituting.
