How Shots Work 🤔

[LuCkySlither]

I love how you make scientific facts so interesting and accessible

[BobbyMushinsky]

I am a nurse practitioner. This is not a shot, this is an IV push you're talking about. A shot goes into subcutaneous or muscle tissue

Rare moments Zack isn't trying to traumatize us

[Mr-Unknown-jl]

Zach videos is such as addict that it feels to watch again again because of the animation and the information he gives us.

[azerkfv]

Zack’s animations are literally S tier

[Lizardouz]

Zack is just getting more and more terrifying animations 🎥

Zack just made my fear of Needles even worse

[wowueewow]

You’re awesome thank you for these medical shorts!

[SleepersJeepersGacha-fr]

As someone who was at the hospital last week this video made my arm feel attacked

[HeisenbergFam]

Zack is best hype man when it comes to promoting his own products

[MikelBasurtoMusic]

If Zack traumatizes us again by labeling his name on everything he adds, he'll make his own merch 💀

[Sirfearair]

i think its so cool how your skin heals over time

[MarmaladeFinalBoss]

This is the one Zach D films short that wasn’t traumatising 😭
