Selank Near Me: The Nearest 5 mg/mL Is One You Mix

The results fall into four groups, and none of them is a supplier in the sense the query intends. We are not naming businesses, because a real local list would be different in every city and inventing one would be worse than useless.

Only the third row can ever say yes, and it is the row where the least is knowable in advance. A retail bottle may carry a strength, a batch number and a certificate, or it may carry a brand name and nothing else. That is a documentation question rather than a geography question, and proximity does not improve the answer.

This is a genuinely different picture from the one our NAD+ local page describes, where a real service channel exists and a clinic can quote you a session price for material going into a bag. Selank has no equivalent. It is closer to the MOTS-c situation: a compound with an active online market and no local counter at all.

The pharmacy result is the one most people click, so it is worth being exact about why it fails.

Under section 503A of the Federal Food, Drug, and Cosmetic Act, a pharmacy compounding from a bulk drug substance needs that substance to be the subject of an applicable USP or NF monograph, or a component of an FDA approved drug, or on the bulk drug substances list FDA maintains for this purpose. Selank meets none of the three, and there is no fourth route.

Its actual position is more specific than most pages report. Selank acetate (TP-7) was nominated for the 503A bulks list and placed in category 2 under FDA's interim policies. The nomination was then withdrawn by the nominator, and Selank now appears on FDA's list of bulk drug substances nominated but withdrawn. Search the 503A category lists updated 14 May 2026 and it is absent from category 1, category 2 and category 3 alike. If you have read that Selank is "FDA category 2", that is out of date, and our page on the legal position sets out the full sequence with the sources.

So the pharmacist is not being unhelpful and there is no better pharmacy across town. The first step in the chain that ends with a filled prescription does not exist.

Where a local search wants an address, the material wants a volume. The vial contains a labelled 10 mg of dry powder and no solvent at all, so it has no concentration until bacteriostatic water goes in, and the number you choose sets every other number downstream.

At 2 mL the vial is 5 mg/mL, one unit on a U-100 barrel is 0.01 mL and holds 50 mcg, and 10 units draws 500 mcg. The last column reads the same in every row because 500 mcg is half a milligram and half a milligram costs half of $2.375 regardless of what it is dissolved in. Volume changes resolution, not price. The Selank reconstitution calculator will run any volume you enter, and these are laboratory handling conversions for research material rather than instructions for anything else.

If a nearby shop does have something, the useful skill is converting whatever they quote into dollars per milligram, because that is the only figure that sits next to the online listing without further translation.

The gaps that turn up are usually large. A 5 mL bottle at 0.1 percent holds 5 milligrams, so a $50 bottle is $10.00 per milligram, over four times the $2.38 rate on the vial. A 10 mL bottle at 0.3 percent holds 30 milligrams, so the same $50 is $1.67 per milligram, which beats it. The label difference between those two bottles is a handful of characters, and neither price tells you which one you are holding.

There is one more figure worth carrying into any comparison. Both published certificates measured more than the label: 12.29 mg on lot 29-01260229 and 11.86 mg on lot 29-05260628, so the real rate on those fills was $1.93 and $2.00 per milligram rather than $2.38. Those are lot specific measurements and not guarantees, which is why $2.38 stays the headline. The full arithmetic is on our Selank price breakdown.

Proximity is not a quality signal, and a shelf is not a certificate. Four questions separate a local seller worth buying from one worth walking away from, and they are the same four you would ask an online vendor.

• What is the lot number, and is there a certificate for that lot? Not a certificate for the product line. For the lot on the container in front of you. If those two numbers do not match, nothing else on the report applies.
• What does the certificate cover? Purity by HPLC, identity by mass spectrometry against an expected monoisotopic mass of 751.43 Da, and a measured quantity are the baseline. The published certificate for this listing reports 99.32% purity, a measured 751.47 Da, and 12.29 mg per vial.
• Is there an endotoxin or sterility result for that lot? This is the question FDA's stated concern turns on. In its own words, compounded drugs containing selank acetate "may pose risk for immunogenicity for certain routes of administration due to the potential for aggregation and peptide-related impurities", and it "lacks important information regarding any safety issues raised by selank acetate administered to humans". Aggregation and peptide-related impurities are measurable, so this is a testing question. The lot matters more than the product: certificate 29-01260229 carries no bacterial endotoxins test and no sterility screen, while certificate 29-05260628 carries endotoxin below 0.20 EU/mL by kinetic chromogenic LAL and a rapid sterility screen returning no growth. Ask which one applies to the container in front of you.
• How has it been stored, and for how long? A dry vial is the stable form. A solution has been in water since it was filled, so its shelf life has been running the whole time it sat on a shelf, and the portion left is what you are buying.

If a seller cannot answer the first two, the price is not the problem. If they can answer all four, the remaining decision is arithmetic, and this page has given you the conversions to do it.
