Hi everyone,
A quick but extremely useful peptide science tip for all researchers.
Many new users worry that normal-temperature shipping will affect peptide quality. In fact, dry lyophilized peptides are chemically inert and very stable.
Only water and humidity will break down peptide structures — not room temperature.
Our factory peptides are professionally freeze-dried and vacuum-sealed. All moisture is removed during production. This keeps the peptide molecules in a stable dormant state during international transit.
Ambient shipping is completely safe and causes zero degradation.
Once you reconstitute the powder with bacteriostatic water, the peptide becomes active. From that point, cold storage (2–8°C) is required, and freezing the liquid is not allowed.
In short:
✅ Dry powder = stable, safe for normal temp shipping
✅ Liquid solution = sensitive, requires refrigeration
Our Factory Service Highlights
✅ High-purity peptides with complete COA & HPLC reports
✅ Third-party testing supported. Failed quality = we cover test fees + free reshipment
✅ DDP door-to-door, double clearance & tax included
✅ Free reshipment for loss, damage, or customs detention
✅ Multiple payments: Wise, Alipay, Western Union, Bitcoin, USDT
