- Adamax Expedited Cold-Chain
- 24–48 hours
- PCM packs + insulated EPS shipper, 2–8°C maintained
- Temperature data logger + visual indicator in every package
- +$25–40 vs ground
- Only method with post-delivery verification. You know peptide stability before reconstitution
- Standard Ground "Cold Shipping"
- 5–7 days
- Ice packs + foam cooler, no temp guarantee
- None. Relies on customer complaint if degradation suspected
- Baseline cost
- Adequate for stable compounds in mild climates, high risk for GLP-1 agonists or summer shipping
- Ambient Ground Shipping
- None. Room temperature throughout
- None
- Acceptable only for lyophilised powders with documented ambient stability (rare). Inappropriate for most peptides
- International Express with Customs Hold Risk
- 3–10 days depending on clearance
- Varies by carrier, often lost during customs transfer
- Rarely included
- +$60–120 vs domestic ground
- Transit time unpredictability makes cold-chain maintenance nearly impossible. Peptides often arrive degraded
- The cost premium for Adamax shipping. Typically $25–40 over ground rates. Represents less than 5% of the peptide's purchase price for most research-grade compounds. Yet that 5% investment protects 100% of the peptide's bioavailability. Researchers who opt for economy shipping to save $30 on a $600 peptide order risk receiving a product with 40–60% reduced potency, which effectively doubles the per-dose cost while introducing confounding variables into their research protocol.
