Lyophilization
Lyophilization (freeze-drying) is a three-stage dehydration process: (1) freezing the peptide solution, (2) reducing pressure under vacuum, and (3) sublimating ice directly from solid to vapor. The result is a dry, porous powder with greatly enhanced long-term stability.
Lyophilized peptides can maintain stability for 2+ years when stored at -20°C, compared to days or weeks in solution. The porous structure allows rapid dissolution when reconstituted. Most research peptides, including all Healthy Aminos products, are supplied in lyophilized form.
All Healthy Aminos products are for research use only.
