Serum Question: Are Scaly Skin and Healing Factor worth it?

I’m about to switch from Carnivore to Herbivore and it’s prompted me to reevaluate my serum intake. I will be taking:

• Speed Demon
• Marsupial
• Herd Mentality
• Bird Bones
• Egg Head
• Eagle Eyes
• Herbivore
• Adrenal Reaction

Do the pros actually outweigh the cons of Scaly Skin and Healing Factor? Im considering leaving them off the list. (I’m a full-health commando build)

Be interested to hear what people’s thoughts are on the two serums in question :)
