Dymetadrine Xtreme
AST Sports Science
Overview
Dymetadrine Xtreme is designed to provide a strong stimulant-driven energy boost and thermogenic effects. While the caffeine dose is effective for acute performance enhancement, the combination with other stimulants like Yohimbine HCl and Octopamine Hydrochloride raises concerns about synergistic efficacy versus potential for adverse effects. The supporting amino acids (L-Phenylalanine, L-Tyrosine) may aid cognitive function under stress, but their overall contribution to the 'Xtreme' claims is not well-established for consistent, long-term benefits.
The Good
High dose of Caffeine Anhydrous (300mg) capable of delivering significant acute energy and performance benefits.
Contains Green Tea Extract and Theobromine, which offer some mild thermogenic properties and antioxidant benefits.
Provides L-Tyrosine and L-Phenylalanine, which are precursors to neurotransmitters, potentially supporting focus and mood under stressful conditions.
The Bad
High stimulant content may cause significant side effects like jitters, anxiety, increased heart rate, and elevated blood pressure.
Contains Yohimbine HCl, which carries notable risks including interactions with MAOIs and contraindications for individuals with hypertension or anxiety disorders.
Octopamine Hydrochloride lacks sufficient human safety and efficacy data, making its inclusion questionable.
