Semax 5mg
Price range: $ 55 through $ 110
Semax is a synthetic heptapeptide consisting of the ACTH(4-7) fragment (Met-Glu-His-Phe) extended at the C-terminus with a Pro-Gly-Pro (PGP) tripeptide tail, which increases its resistance to enzymatic degradation relative to the unmodified ACTH fragment. It is a frequent subject of laboratory research and is supplied as a lyophilized powder for research use only.
In published in vitro and preclinical research, Semax has been studied in connection with the regulation of gene expression for brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), and with melanocortin-related signaling. These studies are conducted in cell-culture and animal research models. The findings derive from laboratory research and do not describe or imply any effect, benefit, or use in humans or animals.
Published literature has examined Semax across a range of cell-culture and animal research models relating to neurotrophic-factor gene expression and ACTH-fragment peptide biology. These reports reflect controlled laboratory conditions only and do not translate to dosing, treatment, or applications in any other context. Its mechanism is studied alongside related research compounds such as Selank, Dihexa, and P21.

Storage
Storage Instructions:
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
