Logistics
What happens to a pen in transit
A peptide pen ordered from a UK lab reaches your door via a chain of carriers, warehouses, and vehicles. This is the reality of shipping – and it is why the format decision matters as much as the compound decision.
This page covers the physical journey and what it does to peptide stability.
The journey
The typical UK/EU shipping journey
Placeholder: Break down the journey stages: factory, cold chain (or not), export customs, air freight, import customs, courier hub, delivery van, doorstep. Note typical timings for UK and EU customers. Louie: replace this block with your prose.
Temperature
Temperature exposure
Placeholder: Cover typical temperature exposure ranges during international freight. Note the difference between validated cold-chain shipping (rare, expensive) and standard courier flow. Reference the ICAO temperature specifications if useful. Louie: replace this block with your prose.
Agitation
Vibration, shock and freeze-thaw
Placeholder: Cover physical stress: multiple sorting steps, cargo compression, hub temperature swings, freezer trucks in the winter, hot warehouses in the summer. Aggregation risk from repeated freeze-thaw. Louie: replace this block with your prose.
The consequence
What arrives at your door
Two identical peptide products shipped from the same lab can arrive in materially different condition depending on format.
- Freeze-dried, sealed, dry powder. Insensitive to temperature swings within a wide band. Insensitive to agitation. Arrives at day 3 the same as day 1.
- Pre-filled, in solution. Every hour above freezing is degradation time. Every temperature cycle is aggregation risk. What is inside on day 7 is not what was there on day 1.
See Freeze-dried vs pre-filled for the full comparison, and Why peptides degrade for the chemistry.
