Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
Dr. Jekyll Nightmare leans into mood and focus, backed by a real, well-dosed stack — tyrosine, NALT, ALCAR, and Rhodiola all together in one formula.
Pumps get solid support too, mostly from a genuinely well-dosed citrulline amount.
Performance is the comparative weak point, without a beta-alanine or creatine to lean on.
Honest take: A genuinely solid mood and focus formula, held back from being a complete package by the missing performance support.
