Selank TP-7 is a synthetic heptapeptide studied for anxiety and focus. Learn what selank tp-7 is, how it's used, typical doses, and safety concerns.
Selank TP-7 is a synthetic seven-amino-acid peptide studied for anxiety, focus, and stress resilience. TP-7 is an alternate catalog name for Selank, not a separate compound — both terms refer to the same tuftsin analog developed in Russia. Selank is not FDA-approved for human use in the United States and is sold primarily as a research chemical.
What Is Selank TP-7?
Selank is a short peptide built from seven amino acids, which is why the label TP-7 appears in supplier listings and older research papers. The molecule was engineered from tuftsin, a naturally occurring immunomodulatory peptide, then modified to survive longer in the body and act on the central nervous system.
Some product pages write it as selank tp 7, while others list it as TP-7 alone or Selank (TP-7). The naming varies by vendor, but the structure is identical. If a listing implies two different peptides, that is a marketing distinction rather than a chemical one.
It is usually grouped with other Russian-developed peptides such as Semax and is frequently discussed in nootropic and biohacking communities.
How Selank Is Thought to Work
Published animal studies and a small number of human trials point to several mechanisms at once, which is unusual for a peptide of this size:
- Enkephalin protection: Selank appears to slow the breakdown of enkephalins, the body's own calming opioid-like peptides.
- GABA signaling: It is studied for effects on GABA-A receptors, the same target as many prescription anti-anxiety medications.
- Monoamine balance: Research notes shifts in serotonin and dopamine turnover, which may explain reported changes in mood and focus.
- BDNF expression: Some studies report increased brain-derived neurotrophic factor, a protein tied to learning and stress adaptation.
- Immune modulation: Because it derives from tuftsin, it retains some immunomodulatory activity.
None of these mechanisms has been confirmed in large, well-controlled human trials, so the evidence base remains preliminary.
Selank Nasal Spray vs. Injection
Most research and nearly all real-world use involves intranasal delivery. The choice between selank nasal spray vs injection usually comes down to convenience, onset speed, and comfort.
| Route | Onset | Notes |
|---|---|---|
| Intranasal spray | 15–60 minutes | Most studied route; direct nose-to-brain transport; mild nasal irritation possible |
| Subcutaneous injection | 30–90 minutes | Higher systemic exposure; requires sterile technique; more injection-site risk |
| Oral capsules | Not established | Peptides are generally broken down in the digestive tract, so oral bioavailability is considered poor |
A selank spray sold online may contain a different concentration than what was used in published research, and label accuracy for research chemicals is not guaranteed.
What Dosage Charts Claim
There is no standard human dose of Selank. A selank dosage chart shared in forums typically lists 250 to 500 micrograms per intranasal dose, one to three times daily, based on concentrations used in Russian clinical work.
| Route | Commonly cited amount | Frequency | Caution |
|---|---|---|---|
| Intranasal | 250–500 mcg | 1–3× daily | Concentration varies by vendor |
| Subcutaneous | 250–500 mcg | 1× daily | Very little human data on this route |
| Cycle length | 10–30 days | — | No long-term safety data |
These figures are reported for informational purposes, not as a recommendation. Anyone considering a peptide like this should speak with a healthcare professional first.
How Long for Selank to Work?
The question of how long for selank to work depends heavily on the route of administration. Users of the nasal spray often describe a calming effect within 20 to 60 minutes, while injected doses may take slightly longer to peak.
Effects on sleep, worry, and mental clarity — the outcomes people actually care about — are typically described as building over one to four weeks of consistent use, mirroring the timelines reported in small clinical studies.
Anyone expecting a single dose to resolve long-standing anxiety will likely be disappointed. The research frame is gradual adaptation, not immediate relief.
Side Effects and Stopping
Reported side effects are generally mild and include nasal burning or dryness, headache, fatigue, and occasional irritability.
Reported selank withdrawal experiences are uncommon, and published research does not describe a dependence syndrome. Some users still report rebound anxiety or low mood for a few days after stopping, which may reflect the return of underlying symptoms rather than true withdrawal.
Because long-term safety data in humans are limited, anyone using it should track mood changes and stop if symptoms worsen.
Other Peptides People Compare It With
Many readers arrive looking for selank vs semax comparisons, since those two are the most frequently discussed Russian peptides. Semax is generally associated with focus and cognition, while Selank is studied more for calm and stress response; the two are sometimes stacked.
Other common comparisons include Selank versus Selank amidate, a modified version with reportedly greater stability, and Selank versus prescription anti-anxiety medications, which have far more human trial data behind them.
Legal Status in the United States
Selank is not approved by the FDA for any human indication. It is not a permitted dietary supplement ingredient, and products labeled "for research use only" are not intended for human consumption.
Importing it for personal use sits in a gray area, and shipments can be seized by customs. Buyers also face the broader problem of unverified purity: third-party certificates of analysis are useful but not a guarantee.
The bottom line is that Selank and TP-7 are the same peptide, studied for anxiety and focus but not proven as a treatment, and not legally sold as a consumer product in the United States.
Frequently Asked Questions
Is Selank the same thing as TP-7?
Yes. Selank and TP-7 are two names for the same synthetic heptapeptide, a seven-amino-acid tuftsin analog developed in Russia. The "TP-7" code refers to its seven-residue structure, and vendors use the labels interchangeably.
Is Selank safe to use for anxiety?
Selank has only limited human safety data, mostly from small Russian studies, and it is not FDA-approved for treating anxiety. Reported side effects are usually mild, such as nasal irritation and headache, but long-term risks are unknown. Talk to a healthcare professional before using any research peptide.
Is Selank legal to buy in the US?
Selank is not approved by the FDA for human use and is not a legal dietary supplement ingredient in the United States. It is sold online as a research chemical, and importing it for personal use can result in seizure of the shipment. Purity and labeling of these products are not guaranteed.
