Nootropic and Neuropeptide Research Compounds
Our nootropic category holds neuropeptides investigated for their activity at central nervous system receptors and neuromodulatory pathways in laboratory models. These are characterized research chemicals for in-vitro and preclinical study, and they are not sold for use in humans or animals.
Semax 10mg is a synthetic ACTH(4-10) analogue studied for its influence on BDNF and NGF expression in rodent brain tissue and neuronal culture. Selank 10mg, a tuftsin-derived heptapeptide, is investigated for its interaction with GABAergic signaling and enkephalin-degrading enzyme systems in preclinical models. DSIP 5mg, the delta sleep-inducing peptide, appears in electrophysiological research on slow-wave activity and hypothalamic signaling in animal studies. PT-141 is examined as a melanocortin receptor ligand with central nervous system activity in receptor-binding and animal-model literature.
What researchers study in this category
Work published on these sequences tends to focus on blood-brain-barrier permeability, receptor affinity and selectivity, neurotransmitter turnover, and the stability of short peptide chains in biological buffers. Researchers frequently compare several analogues within a single assay, which is why sequence purity and accurate molecular identity matter here as much as in any category we stock.
All four compounds ship from the United States and are manufactured to a minimum 99% HPLC purity specification. Batch certificates of analysis (COAs) are published on many product pages, giving HPLC chromatograms and mass-spectrometry data that a laboratory can check against its own incoming-material procedures. Peptides arrive lyophilized and are reconstituted at the bench with an appropriate laboratory diluent.
No statement on this page describes an outcome, an application or a method of use involving people. These neuropeptides are experimental materials whose published evidence exists entirely in cell culture and animal research, and they are supplied only to qualified investigators, universities and commercial laboratories. Storage, handling and disposal remain the responsibility of the receiving laboratory.

Frequently asked questions
What do the peptides in the nootropic category act on?
The sequences here are investigated for their interaction with the central nervous system in preclinical models. Semax and Selank are short peptides derived from endogenous regulatory molecules and studied in neuropeptide signaling, DSIP is investigated for its role in sleep-associated regulation, and PT-141 is a melanocortin receptor ligand examined for central signaling. All four are laboratory research chemicals and are not for human or veterinary use.
What is the difference between Semax and Selank?
Semax and Selank are both synthetic heptapeptides, but they derive from different parent molecules. Semax is based on a fragment of adrenocorticotropic hormone, while Selank is built from the immunomodulatory peptide tuftsin with a stabilizing tripeptide extension. The literature investigates them along different signaling routes, so they are often compared rather than combined. Each is listed as a 10mg lyophilized vial at minimum 99% HPLC purity.
How should Semax, Selank or DSIP vials be handled in the lab?
Standard laboratory practice for lyophilized peptides is to keep the sealed vial cold, dry and shielded from light, and to limit temperature cycling by removing it from cold storage only when required. Labels and lot numbers should stay with the vial so it remains traceable to its certificate of analysis. True Form Peptides does not publish reconstitution or usage guidance for research materials.
Does True Form Peptides ship these peptides outside the United States?
No. Shipping is limited to destinations within the United States, and orders typically enter processing within one to two business days before tracking is issued. Everything in this category, including PT-141, DSIP, Semax and Selank, is sold strictly as a laboratory research chemical and is not supplied for human or veterinary use. Shipments are packed for transit of sealed lyophilized vials.
