Semax 10mg

Semax 10mg — Ultra-Purity Research Grade

What Is Semax?

Semax is a synthetic nootropic peptide based on the ACTH(4-7) sequence (Met-Glu-His-Phe-Pro-Gly-Pro). It was developed in the Soviet Union during the 1980s at the Institute of Molecular Genetics and has been used in Russian medicine as a prescription nootropic for decades. In Russia, it remains an approved pharmaceutical used in the treatment of stroke, transient ischaemic attacks (TIAs), cognitive decline, and optic nerve disease.

Unlike many research peptides which are primarily researched for physical recovery, Semax is firmly in the neurological and cognitive category — one of the few peptides with an actual clinical approval history, even if that approval is limited to Russia.

X-Fuel Semax is supplied at 10mg per vial, lyophilised to ultra-purity research grade.

Why the Community Uses It

Semax has a devout following in the nootropics community, particularly among practitioners who prioritise evidence depth over anecdote. Key areas of interest:

BDNF Upregulation

Brain-Derived Neurotrophic Factor (BDNF) is one of the most important proteins in brain health — associated with neuronal survival, synaptic plasticity, and memory formation. Semax has been shown in animal studies to significantly upregulate BDNF expression, particularly in the hippocampus. This makes it highly relevant to anyone researching learning, memory, or neuroprotection.

Focus & Cognitive Clarity

Users consistently report improved focus, reduced mental fatigue, and sharper working memory during Semax protocols. This aligns with its research profile around dopaminergic and serotonergic system modulation.

Neuroprotection

Given its clinical use in stroke and cognitive impairment in Russia, Semax’s neuroprotective properties are well-supported by preclinical and some clinical literature. Research has explored its role in reducing ischaemic neuronal damage and supporting recovery of cognitive function following neurological events.

Mood & Anxiety

Some users and research note effects on stress resilience and anxiety reduction — potentially linked to its influence on the HPA axis and serotonergic tone.

Mechanism of Action

Semax acts through multiple pathways: it mimics ACTH fragments that interact with melanocortin receptors, modulates the expression of neurotrophin genes (BDNF, NGF), and influences monoamine neurotransmitter systems. Its Pro-Gly-Pro extension improves CNS penetration and extends the peptide’s half-life compared to the parent ACTH fragment.

Administration Routes

Semax has historically been used as a nasal spray in Russia (intranasal administration allows direct nose-to-brain delivery bypassing the blood-brain barrier). Subcutaneous injection is also researched. X-Fuel’s lyophilised format allows reconstitution for either route.

Reconstitution & Storage

Reconstitute with sterile or bacteriostatic water. Store unreconstituted at 2–8°C. Reconstituted solution should be refrigerated and used within 14–21 days.

Storage Information

Store lyophilised vial refrigerated at 2–8°C away from light. Reconstituted solution: refrigerate and use within 14–21 days. Semax is more sensitive than some peptides — maintain cold chain.

Usage & Reconstitution

Reconstitute with sterile or bacteriostatic water. Can be administered subcutaneously or intranasally (via nasal spray adapter). Intranasal is the traditional Russian clinical route for direct nose-to-brain delivery. Common reconstitution: 1–2mL per 10mg vial.
