- The following table compares cost structure across supplier tiers for a standard 25mg daily research protocol (750mg monthly requirement).
- Tier 1: Unverified Bulk
- $0.50–$0.80
- $38–$60
- None
- No
- $58–$90
- Lowest upfront cost but highest protocol variance. Purity claims unverifiable and batch-to-batch consistency poor
- Tier 2: Domestic In-House Testing
- $1.00–$1.40
- $75–$105
- In-house HPLC only
- Limited
- $95–$135
- Mid-range pricing with self-reported purity data. Suitable for preliminary work but not publication-grade research
- Tier 3: Independent Third-Party Verification
- $1.60–$2.00
- $120–$150
- Third-party HPLC + MS
- Full batch traceability
- $155–$210
- Highest per-dose cost but only tier offering externally validated purity and reproducibility across studies
- Our team sources exclusively from Tier 3 suppliers for any protocol requiring documented reproducibility. The cost premium is the smallest controllable variable in a research budget. Far smaller than the cost of invalid results from impure or mislabeled compounds.
