There's no context here so I don't know how to rate it… but you could make it stronger like 'How Protein Powder Silently Kills You' (as long as it is compliant)

@Chetan Sathe Just saying Protein might make it confusing for someone (what do you mean protein is good right?).... Again all this depends on the context and your offer... You gotta show the product you're writing for and what you're writing otherwise it doesn't make sense

Both helped me a ton... Mostly it makes things simple for you in your head on what to actually do (removed the confusion... Just need to follow the steps there)
