Description
N-Acetyl Semax Amidate is the most heavily stabilized version of the ACTH-derived research peptide, with protective caps at both ends of the chain. Limitless Life Nootropics supplies it in 20mg and 30mg vials, made in the USA and independently tested.
What Is N-Acetyl Semax Amidate?
Peptides can be degraded from either end: aminopeptidases attack the N-terminus and carboxypeptidases attack the C-terminus. This molecule addresses both. An acetyl group protects the front of the chain, while converting the terminal carboxylic acid into an amide protects the back.
C-terminal amidation also removes a negative charge, which can make a peptide more lipophilic and may influence how readily it crosses biological membranes. Together, the two modifications make this compound a popular choice for researchers investigating whether greater stability produces stronger or longer-lasting effects in neurological models.
It is offered in Premium lyophilized and Non-Lyophilized grades, in 20mg and 30mg sizes.
Research Applications
Published preclinical work has examined this peptide across several areas of investigation:
- Peptide stability against amino- and carboxypeptidases
- Membrane permeability of amidated peptides
- Neurotrophic signaling and neuroprotection
- Long-duration behavioral and cognitive studies
- Head-to-head comparisons with Semax and N-Acetyl Semax
Researchers can review peer-reviewed studies on this compound through the National Library of Medicine (PubMed) database.
