- Professional Assessment
- Budget tier appears cheaper per vial but delivers 33% fewer applications due to purity variance and degradation losses. Research-grade costs $1.43 more per application but eliminates the under-dosing risk that extends protocol timelines by 3–5 weeks. For 12-week protocols, budget tier requires 14–15 vials ($322–$345), research-grade requires 10–11 vials ($680–$748). The $335–$403 difference buys dose certainty and predictable timelines.
