Selank dosage, framed for intranasal research.

Selank is a synthetic analog of the immunomodulatory peptide tuftsin, studied for anxiolytic and neuro-regulatory questions. Like the other nasal nootropics Titan stocks it is referenced in micrograms per intranasal administration rather than milligrams, and modelled around the behavioural window being measured. Its tuftsin lineage gives it a different research profile from the ACTH-derived Semax it is often paired with. This page lays out the microgram framing, timing, and metered-spray delivery for Selank as a laboratory reference — not a human protocol or medical advice.

A tuftsin analog, not an ACTH fragment

Selank is a heptapeptide based on the endogenous immunopeptide tuftsin, with terminal modifications added for stability. That tuftsin origin is why its research sits around anxiolytic and immunomodulatory questions — a distinct lineage from Semax, which is an ACTH(4-10) fragment studied for cognition. Researchers pairing the two are combining two different mechanisms, not two versions of the same one.

Selank anxiolytic research

Microgram ranges in the literature

Anxiolytic and behavioural research models intranasal Selank in microgram amounts per administration, with study designs spanning a single-dose window depending on the endpoint. As with Semax, the defining feature is an acute per-session amount delivered nasally rather than a milligram daily total. These figures are a laboratory reference, not a human protocol.

Semax vs Selank framing

Stabilised peptide, acute timing

Selank's terminal modifications slow enzymatic degradation relative to native tuftsin, but it is still studied as a short-acting peptide rather than an accumulating one. Research designs administer it acutely — around the behavioural window being measured — instead of relying on a standing daily build-up. Timing relative to the experiment is the variable that matters most.

Why timing matters

Metered spray — no reconstitution

Titan supplies Selank as a ready-to-use metered nasal spray, so there is no bacteriostatic-water reconstitution step like a lyophilized injectable vial. Each actuation delivers a fixed volume, which is what lets a per-session microgram reference map onto a known per-spray amount. Storage and handling follow the nasal-spray shelf-life guidance rather than vial reconstitution math.

Identity and concentration to confirm

For a nasal-spray format, the verification points are peptide identity and the labelled concentration per actuation. Titan's Selank is characterised by mass-spec identity and HPLC purity against a ≥99% internal target on a lot-matched release sheet — so the microgram references on this page map onto a known concentration rather than an assumed one.

Research-use framing

Selank in this format has no regulatory approval for human use in most jurisdictions. The microgram ranges and timing here are reproduced as a laboratory research reference for in-vitro and behavioural-modelling work — not instructions for human use. Titan supplies Selank strictly as a research reagent, and nothing on this page is medical or dosing advice.

The variables an anxiolytic-research protocol weighs for intranasal Selank — the peptide's tuftsin origin, the microgram unit convention, the stabilised-but-short profile that drives acute timing, and the metered-spray delivery that removes reconstitution.

Questions researchers ask

Before you order.

What is the research dosage for intranasal Selank?
Anxiolytic and behavioural research models intranasal Selank in microgram amounts per administration, with study designs spanning a single-dose window depending on the endpoint. It is referenced as an acute per-session amount delivered nasally rather than a cumulative milligram daily total. These figures are a laboratory reference, not a human dosing protocol or medical advice.
How is Selank dosing different from Semax dosing?
Both are intranasal heptapeptides referenced in micrograms and administered acutely, so the unit and route conventions are similar. The difference is lineage and research focus: Selank is a tuftsin analog studied around anxiolytic and immunomodulatory questions, while Semax is an ACTH(4-10) fragment studied for cognition and neuroplasticity. Researchers who pair them are combining two distinct mechanisms.
Does Titan's Selank nasal spray need reconstitution?
No. Titan supplies Selank as a ready-to-use metered nasal spray, so there is no bacteriostatic-water reconstitution step like an injectable lyophilized vial. Each actuation delivers a fixed volume, which is what makes per-session microgram references practical to apply. Storage follows the nasal-spray shelf-life guidance rather than vial reconstitution math.
Why is Selank administered acutely rather than daily?
Selank's terminal modifications slow degradation relative to native tuftsin, but it is still studied as a short-acting peptide rather than an accumulating one, so research designs administer it acutely around the behavioural window being measured rather than on a standing daily schedule. Timing relative to the experiment matters more than dosing frequency.
Is Selank approved for human use in this format?
No. Titan's Selank nasal spray has no regulatory approval for human use in most jurisdictions. Titan Peptide Lab supplies it strictly as a research-use-only reagent for in-vitro and behavioural-modelling laboratory work — not for human or animal consumption, and not for diagnostic, therapeutic, or preventative use.
