Where can I buy the Semax + Selank stack for research?

Buy from a supplier that supplies both in the intranasal format with stated concentrations per actuation, lot-matched release sheets, and clear research-use language. Titan Peptide Lab supplies the Selank + Semax stack at $105 as two 15mL nasal sprays for in-vitro laboratory research with crypto-only checkout. It is not for human use.

How much is the Semax + Selank stack?

The Selank + Semax stack is listed at $105 as a set — below the $119.98 combined list of the two single sprays. Discounts apply at checkout — FIRST10, BULK15, TITAN20, and VIP25 — and the displayed total is what the crypto payment settles at.

Why are Semax and Selank studied together?

Semax is studied in cognition, attention, and BDNF-signalling research; Selank in anxiolytic, immune-regulatory, and stress-response research. The pair covers complementary angles of neuropeptide research, which is why they are frequently discussed and sourced as a set. Titan makes no human-use or efficacy claims.

Does each spray in the stack have its own COA?

Yes — because the set is two distinct peptides, each spray ships with its own lot-matched release sheet keyed to the lot code on that bottle, with an HPLC main-peak purity result and a mass-spec identity confirmation, rather than a single shared document.

Is the Semax + Selank stack approved for human use?

No. Research-grade Semax and Selank are not approved for human use. Titan supplies the stack strictly as research-use-only compounds for in-vitro laboratory work — not for human or animal consumption, and not for diagnostic, therapeutic, or preventative use.

Where to buy the Semax + Selank stack, in the intranasal format.

Semax and Selank are the two most-cited nootropic peptides in the intranasal literature, and they are frequently studied as a pair — Semax on the cognition/attention side, Selank on the anxiolytic/regulatory side. Titan supplies them as a documented two-spray set at $105, both pre-formatted for intranasal research with no reconstitution.

Selank + Semax stack — $105 Semax vs Selank

Why the two are studied together

Semax is an ACTH(4-10)-derived heptapeptide studied in cognition, attention, and BDNF-signalling research; Selank is a tuftsin-derived peptide studied in anxiolytic, immune-regulatory, and stress-response research. The pair is discussed together because the two cover complementary angles of neuropeptide research — which is why they are sourced as a set.

Both pre-formatted intranasal

The stack is two 15mL sprays — Semax at 1mg per actuation and Selank at 750mcg per actuation — pre-formatted for intranasal research with no lyophilized vials to reconstitute. The intranasal route is the format most of the Semax and Selank literature uses, so the documented sprays map directly onto how the compounds are studied.

The stack price and tiers

The Selank + Semax stack is listed at $105 as a set — below the combined single-spray list of $119.98. FIRST10 takes 10% off a first order, BULK15 15% off three or more items, TITAN20 20% off orders over $250, and VIP25 is the returning-researcher tier. The figure on screen is what the crypto order settles at.

Documentation on each spray

Because the set is two distinct peptides, each carries its own lot-matched release sheet keyed to the code on that bottle, with an HPLC main-peak purity result and a mass-spec identity confirmation. You are verifying two units, so confirm the paperwork on each rather than assuming the stack shares one document.

How checkout settles

Titan is crypto-only — BTC, USDC, or SOL. The network and wallet are shown before payment and an order ID is logged with support first. Paying in USDC holds the total at the quoted figure even if BTC moves between cart and confirmation.

Storage and shelf life

Both are intranasal solutions, which store differently from lyophilized vials. Titan documents the nasal-format storage and shelf-life expectations for the set so both sprays behave predictably across a study window rather than degrading silently.

The detail, in plain terms

Two documented sprays, one nootropic pairing.

The Semax + Selank set is two compounds sourced together, not a blended product — so each spray is independently verifiable. The set price sits below buying the two sprays separately.

Semax: 15mL intranasal spray · 1mg/actuation — cognition/attention research.
Selank: 15mL intranasal spray · 750mcg/actuation — anxiolytic/regulatory research.
Stack price: $105 as a set (vs $119.98 buying both separately).
Format: Both pre-formatted intranasal — no reconstitution.
COA path: A separate lot-matched release sheet for each spray, on request.
Checkout: Crypto-only — BTC, USDC, SOL; on-chain confirm before dispatch.
