FAQ

Common questions

What's the core difference? ▼

Beast Bulk keeps regular Bulk's 200mg stimulant profile and 1.3g taurine, then adds 1.5g Nitrosigine. Bulk Black raises caffeine to 325mg and tyrosine to 2g, but drops taurine and theobromine from the current active formula.

How much caffeine is in Bulk Black? ▼

The linked BULK BLACK Supplement Facts panel lists 325 mg caffeine per full serving. Older 350 mg descriptions should not be used for this panel.

Does Bulk Black have taurine or Huperzine A? ▼

The linked BULK BLACK panel lists 200 mcg huperzine A. It does not list taurine. These are different ingredients, so they should not share a blanket “not included” answer.

Which should I buy? ▼

Beast Bulk for pumps at moderate caffeine; Bulk Black for a stronger stimulant and focus hit. They upgrade different sides of the same base.
