Yes, it means that it was made for human use. which is good.

UGL = Underground lab
Human Grade = From Pharmacy ( made for patients)

[Deezuhl]

UGL gear is made for humans. human grade basically means the way it was made. in other words it was manufactured under the same tolerances and strict standards as the human grade pharmacy gear.
