Important: This peptide is not yet FDA-approved
Selank has not been approved by the FDA for any use in humans. That means it hasn't gone through the rigorous testing process that confirms a drug is safe and effective. Products sold online have not been evaluated by any regulatory body.
What it does
Selank (selank (TP-7 / synthetic tuftsin analog)) is a synthetic peptide that researchers are studying, but it's not yet FDA-approved for any human use. Synthetic analog of the immunomodulatory peptide tuftsin. Modulates GABA, serotonin, and dopamine systems. Also acts on BDNF expression and has immunomodulatory effects. Anxiolytic without sedation.
The research is still early. Most studies so far are in animals or lab settings, so we don't know for sure how well this translates to real-world results in people.
How it's taken
Nasal spray (most common)
Subcutaneous injection
How people access it
Category 1 compounding-eligible since February 2026. Requires a prescription sent to a licensed compounding pharmacy. Most commonly used as a nasal spray.
Regulatory Status
Not FDA-approved in the US. Approved as a pharmaceutical in Russia. Category 1 compounding-eligible since February 2026.
Any use in humans outside of an FDA-authorized clinical trial would require an Investigational New Drug (IND) application. Products marketed as “for research use only” are not legally intended for human administration.
What the Evidence Shows
The evidence base for Selank consists primarily of preclinical studies (animal models and in vitro experiments). There are no completed, large-scale, peer-reviewed clinical trials establishing safety or efficacy in humans. The gap between promising animal data and proven human benefit is substantial — many compounds that show effects in animal studies fail to demonstrate safety or efficacy in human trials.
Marketing claims made by online sellers and “peptide clinics” frequently overstate the evidence and omit critical information about risks and unknowns.
Other options to consider
Depending on what you're hoping to achieve, there may be FDA-approved treatments that have been rigorously tested and proven to work. Discuss evidence-based options with your own healthcare provider to find what fits your specific goals.

Common Questions
No. Selank is not FDA-approved for any indication. It has no approved NDA or BLA and cannot be legally marketed as a drug for human use.
There is insufficient clinical evidence to establish the safety of Selank in humans. Most available data comes from preclinical studies. Using unapproved substances carries risks including unknown side effects, contamination, and incorrect dosing.
Depending on the condition you are seeking to treat, FDA-approved options may be available. Discuss evidence-based treatments with your own healthcare provider to find options that have undergone rigorous safety and efficacy review.
