Read the record in context
Semax's routes include nasal and subcutaneous recording, but its timing context is rat literature. The 10 mg package is another kind of reference altogether. Reading the species limitation first is more informative than comparing the 0.75-hour scalar with another compound's matching number.[1]
What the research says
The cited rat study investigated how intranasally administered Semax entered blood and brain tissue. Researchers labeled the peptide with tritium and followed the label after administration. The design examined penetration and breakdown of an ACTH-fragment analog, rather than testing a clinical outcome in humans.[2]
At two minutes, the investigators detected radioactivity in brain tissue and separated the proportion attributable to intact Semax from metabolites. They also described rapid enzymatic degradation, with the Pro-Gly-Pro fragment becoming prominent in biological samples. Intact peptide and total radioactivity therefore represented different measurements.[2]
The results provide a route-specific animal account of tissue entry and metabolism. They do not characterize human subcutaneous disposition, despite that route being available for recording in the app. The library's short timing value is a low-confidence model input rather than a directly measured human half-life from this paper.[2][1]
Cited amounts
The library records 10 mg as a supplier catalog package amount. This is the total listed in that presentation, not an amount selected for administration. No personal dosing range is inferred from it.[1][3]
Open the calculator for amount conversionsHalf-life and timing
Forty-five minutes per halving makes a two-interval example 90 minutes long. At that point the model retains one quarter; at 225 minutes it retains one thirty-second. The latter is five times the stored 0.75 hours. These calculations do not measure a human nasal preparation and cannot establish its absorption. The graph also contains no second recorded amount. A clean declining bar is therefore an explanation of the tracking estimate, not evidence that both available routes share this exact profile.[1][5]
Continue to the calculatorReconstitution
The catalog's 10 mg is a total mass, not a concentration per nasal spray or a device setting. With a hypothetical 2 mL final liquid volume, mass divided by volume gives 5 mg/mL. Multiplying by an illustrative 0.1 mL gives 0.5 mg. Those inputs do not describe an actual nasal device. Without independently known delivered volume, the concentration equation cannot infer the amount associated with any spray, and the guide provides no formulation or administration instructions.[3]
Tracking it in PinPoint
From a reference to a record
Built for peptide, TRT, and GLP-1 schedules. Set up your vial in seconds, log every dose, and see your modeled levels between doses. Enter vial size in mg, mcg, or IU and water volume for instant concentration and syringe units. Track vials and prefilled pens side by side.[4]
The Home curve models your levels between doses from published half-life data. Drag to scrub modeled values at any timestamp, or preview 30 days of a dose pattern. Ask PinPoint provides educational reference with sources; it never recommends a dose or a schedule change. These features record and visualize entered information, with the limits of each compound's source data still applying.

- What does a Semax vs Selank comparison establish?
- The library describes Semax's timing context as rat literature and Selank's citation as a human clinical-context study that does not state the model inputs. Both use uncertain tracking values. Equal stored half-lives do not make the evidence or compounds interchangeable.[1][2]
- Can a Semax reconstitution calculator determine an amount per nasal spray?
- Concentration alone does not specify how much liquid a device delivers. The library's 10 mg catalog package supplies no spray-volume input. A calculator cannot reconstruct that missing device quantity from the compound's half-life or name.[1][5]
- What does the Semax source contribute to the model?
- The library identifies rat literature as its timing context and marks human model data as limited. It does not describe the reference as a measured human nasal or subcutaneous dataset. That source qualification remains attached to the 45-minute input.[1][5]
- Can a peptide tracker app record Semax?
- PinPoint's compound library includes Semax. The app description covers logging compound, dose, site, and pain level, as well as viewing modeled levels between recorded doses. The curve uses published reference inputs and does not account for individual variation. The tracker records the schedule entered by its user; it does not choose a dose or recommend a schedule change.[1][4]
