Reviewed by Garett Reid, MSc, CSCS, CISSNStrength coach & sports nutrition specialist · · About the author
This is one of Bucked Up’s strongest pre-workout formulas. It’s for experienced pre-workout users who have built a high stimulant tolerance and want something substantially stronger.
It delivers a massive 400mg dose of caffeine, which is very high, and then adds 2mg Rauwolscine and 100mg Theobromine. This is for stimulant lovers.
Past the energy, what’s interesting is that the rest of the formula is genuinely comprehensive. Mother Bucker delivers a full, evidence-based daily dose of 6.4g Beta-Alanine for muscular endurance, while 1.5g Nitrosigine® and 4g L-Citrulline create a strong pump foundation. Then 1.5g L-Tyrosine, 300mg Alpha-GPC, and Huperzine A give a nootropic hit to help you stay mentally engaged.
However, its benefit is also its drawback: it’s intense, not suitable for beginners, and potentially too aggressive even for some regular pre-workout users. The 6.4g Beta-Alanine is also pretty high and will almost definitely give you “the tingles.”
But for someone with the stimulant tolerance to handle it, Mother Bucker stands out because the formula isn’t just extreme for the sake of caffeine. It delivers substantial doses for endurance, pumps, hydration, and focus.*
