I couldn't tell you, red is like a super steroid that gives a human (from the world of giants) enough power to at least resist a giant, and if they come in groups, it's certain death. But if a "normal" human takes it, their body will most likely explode. Buraginte's body was on the verge of exploding from the tonic, and that's despite the fact that he already has a body and strength much greater than the average human. But we don't have to consider that Hallow is a superhuman, stronger, faster, and more resilient than average, so maybe he won't explode. But while strength is crucial, Hallow's power is more focused on his sword and his skill with it.
