Semax is a synthetic peptide derived from adrenocorticotropic hormone (ACTH) fragments and is widely studied for its potential neuroprotective and nootropic properties. Research has explored Semax’s role in cognitive support, neural adaptation, and stress-response modulation. Although it has historically been investigated in contexts such as mood regulation and neurological disorders, current studies continue to examine its broader influence on learning, memory, and neuroplasticity.
One of the primary mechanisms associated with Semax is its ability to modulate levels of brain-derived neurotrophic factor (BDNF), a key molecule involved in neuronal growth, synaptic plasticity, and the brain’s ability to adapt to new experiences. Semax has also been shown in research models to inhibit the breakdown of enkephalins—endogenous peptides linked to pain modulation, inflammatory responses, and emotional processing—making it a valuable peptide for studying neurochemical balance and stress resilience.
Scientific investigations into Semax have examined its potential influence on attention, mental clarity, information processing, and memory formation. Additional areas of research include its role in supporting cognitive function under stress, promoting neural recovery mechanisms, and modulating anxiety-related pathways. Because of these multifaceted actions, Semax remains a prominent molecule in the study of neurobiology, cognitive enhancement, and brain health

Frequently Asked Questions
-
Commonly known and understood peptides in the medical community are insulin, oxytocin, collagen. These are all peptides.
As a matter of fact, the human body naturally produces more than 7,000 known peptide types. With this many peptides, they are used in a wide variety of the body's systems and are essential to the way we function and age.
Peptides are very tiny proteins made up of short chains of amino acids. They signal the cells in your body to act in certain ways. As a result, peptides are responsible for how you function, feel, look and live overall. Since different peptides affect different cells and functions, they can be highly tailored and targeted to treat a full spectrum of health, wellness, fitness, metabolism, aging and cognitive conditions.

Peptides should be stored in a refrigerator (2°C to 8°C) after reconstitution. Lyophilized (powdered) peptides should also be kept in a cool, dry place until reconstitution or in a freezer for long term storage.
To preserve the integrity of peptides, proper storage is essential. While some peptides are more susceptible to degradation than others, knowing and implementing the best practices for peptide storage can greatly lengthen their stability.
Once peptides have been received, make sure 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 acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months room temperature is adequate.
For longer term storage it is 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.
Avoid repeated freeze-thaw cycles. This can increase the peptide’s susceptibility to degradation. Also, frost-free freezers should be avoided to store peptides, as temperatures can fluctuate widely during defrosting cycles.
-
Lyophilization is a freeze-drying process that removes moisture from a compound to improve stability during storage and transport. Many peptides are supplied in lyophilized (powder) form for this reason.
Peptides in dry form are generally more stable than liquid formulations. This allows for longer shelf life prior to preparation and helps preserve integrity during shipping. -
A Certificate of Analysis (COA) is a quality document that summarizes analytical testing performed on a specific product batch. It helps confirm identity, purity, and consistency. Typically includes:
- Product name
- Peptide sequence or abbreviation
- Batch or Lot Number
- Manufacturing date
- Test or report date
Identity testing (MS) confirms that the compound analyzed matches the intended molecular structure.
Purity (HPLC) refers to how much of the sample is the intended compound versus related fragments or residuals.
-
Sterility and endotoxin testing are quality and contamination-screening tools.
Sterility testing is performed to assess whether a sample contains viable microorganisms (such as bacteria or fungi) under specific test conditions. It is a growth-based test, meaning samples are incubated and observed over time.
Endotoxin testing screens for lipopolysaccharides (LPS) — components of the outer membrane of certain bacteria. Sterility and endotoxin testing may not be required or meaningful for every peptide due to:- Synthetic manufacturing processes that do not involve biological growth media
- Short peptide sequences that undergo cleavage, purification, and solvent exposure
- Lyophilization, which limits microbial viability
- Batch handling and packaging format
While sterility and endotoxin testing are not required for all peptides, Soma goes above and beyond standard industry practices by offering sterility and endotoxin reports on products and upon request. This additional testing reflects our commitment to transparency, quality oversight, and providing partners with robust batch-level documentation to support their internal review and compliance processes. - Synthetic manufacturing processes that do not involve biological growth media
