Description

Semax is a modified fragment of adrenocorticotropic hormone (ACTH 4–10) that retains biological activity in neurological research models. Unlike full-length ACTH, Semax is studied primarily for its central nervous system activity rather than endocrine adrenal stimulation.

In research environments, Semax is investigated for:

Modulation of neurotrophic factors (e.g., BDNF expression pathways)
Regulation of dopaminergic and serotonergic signaling systems
Neuroprotective pathway models in experimental settings
Cognitive and memory-associated signaling pathways (preclinical research)

Key Scientific Features

ACTH (4–10) synthetic analog peptide
High-purity research-grade formulation
HPLC/MS validated identity (batch dependent)
Lyophilized for long-term stability
Full Certificate of Analysis (COA) included
Manufactured under controlled laboratory conditions
Suitable for neurobiological research models

Research Applications (Non-Therapeutic)

Based on peer-reviewed scientific literature — not intended as medical claims.

Semax is studied in laboratory settings involving:

Neurotrophic signaling pathways (BDNF-related mechanisms)
Central nervous system peptide receptor interactions
Neuroplasticity and synaptic modulation research models
Stress-response signaling pathways in brain tissue models
Dopaminergic system regulation in experimental studies
Cognitive function–related biochemical pathway research (preclinical)

Scientific Evidence & References

Semax has been studied primarily in neuropharmacology and peptide neuroscience research:

Neuroprotective Peptides and Semax Research Overview
ACTH (4–10) Derivatives and CNS Activity Review
BDNF Signaling and Neurotrophic Modulation Studies

These studies describe Semax-related peptides in neurotrophic regulation, CNS signaling, and experimental neurobiology.

Mechanism of Action

In laboratory models, Semax is studied to influence:

Expression of brain-derived neurotrophic factor (BDNF) pathways
Regulation of monoaminergic neurotransmitter systems (dopamine, serotonin)
Modulation of cAMP-related intracellular signaling pathways
Neuroadaptive and synaptic signaling processes in experimental models

Handling & Storage

Semax is supplied as a lyophilized peptide powder requiring proper laboratory handling:

Store at 2–8°C
Protect from light and moisture
Avoid repeated freeze-thaw cycles
Reconstitute only under controlled laboratory conditions

Why Researchers Choose Semax

Well-studied ACTH-derived neuropeptide analog
Strong relevance in neurotrophic and CNS research
High analytical purity and batch consistency
Extensive published literature support
Reliable COA and traceability documentation
Used in neurobiology and peptide signaling studies

FAQ's

Research Use Only / Not for Human Consumption

These products are intended for laboratory research purposes only, and are not for human or animal consumption. The products are not intended to diagnose, treat, cure, or prevent any disease. The products should not be used as a food, drug, cosmetic, or other household use. By accessing this website or purchasing from this website, you agree that that it is your sole responsibility to ensure compliance with applicable laws and regulations within your jurisdiction; and you understand and acknowledge that no information on this website should be construed as medical advice.

Product Testing

We verify every batch of every product through accredited, independent third-party laboratories. Since each product requires unique analytical methods and equipment, we collaborate with specialized laboratories and PhDs in analytical and organic chemistry to design our testing protocols.

Analytical techniques we utilize include: NMR, FTIR, HPLC, LC-MS, GC-MS, TLC, ICP-MS, Gravimetry, UV-Vis, Titration, Melting Point, and Organoleptics.
We primarily test for purity, content, sterility, and endotoxins (LPS).

Product Appearance Variations

Variations in color, texture, odor or even biochemical properties may occur due to polymorphy (differences in crystal structure).These variations do not compromise product quality.

Peptide Form

Our peptides are provided in lyophilized powder form to ensure maximum stability. In any other format, peptide integrity would rapidly degrade before reaching the customer.

Optimal storage: Below –20 °C.
Short-term storage: Refrigeration at 4 °C for up to 2 years.
Room temperature tolerance: 4–6 weeks with minimal degradation if protected from direct sunlight (suitable for international shipping).

Peptide Top Colors

Images on our site display white tops for illustration purposes only. In practice, vial tops may vary in color to help our staff distinguish products during processing.

Peptide Powder Appearance

Lyophilized peptides typically form a solid cake. However, during transit, the cake may break or appear uneven. This is an aesthetic issue only and does not impact quality, potency, or purity.

Some peptides and proteins may appear larger due to buffering requirements. This is normal.

Storage Instructions

Storage instructions are provided on each product listing and product label.

General storage: Store in a cool, dry place away from heat, moisture, and sunlight.
Best practice: Refrigeration or freezing is recommended for long-term stability.

Solution Flakes, Precipitation, and Separation

Solution-based products may occasionally:

Crystallize (form flakes)
Precipitate (fall out of suspension)
Separate (form layers)
Lose homogeneity

This typically occurs during cold transit or accidental freezing. To restore uniformity:

Warm the vial in 50–70 °C water for 5–10 minutes.
Shake vigorously to re-suspend.

If the product does not return to homogeneity, please contact us.

Extreme Temperature Exposure

All molecules degrade over time, but proper storage significantly slows this process.

Low temperature exposure: Generally safe; may cause precipitation in solutions but does not accelerate degradation.
High temperature exposure: Prolonged exposure may accelerate degradation.
- Example: A product requiring room temperature storage exposed to 115 °F for a few days will not show measurable degradation once properly stored again.
Cold-storage products (–20 °C): Short-term exposure (<24h) to ambient temperatures does not significantly degrade the product unless oxygen, moisture, or sunlight are also present.

Accidental Exposure or Ingestion
