Reagent infused materials are broken

[Iatots]

I made a synthflesh jumpsuit and it failed to heal my 20something brute damage.
I also made a pentetic acid jumpsuit a while ago, and it caused brute damage? This was not replicated with PA shoes though.

synthflesh heals on external application, not injection

Wait, so it counts as injection?
I thought it would count as contact, since not only have I heard of people using it successfully but witnessing myself a person healing with no meds application and attributing it himself to his jumpsuit.
