Selank dosage by bodyweight
Reference dose ranges scaled across bodyweight bands, anchored to the most-cited research dose (250 mcg @ 75 kg). Educational only, never a recommendation.
| Bodyweight band | Reference dose range | At U-100 (1 mg/mL) | Vol. on U-100 (5 mg / 2 mL) | 5× t½ elapsed |
|---|---|---|---|---|
| <60 kg / <132 lb | 156–211 mcg | 0.16–0.21 mL | 6–8 units0.06–0.08 mL | 10 h |
| 60–75 kg / 132–165 lb | 191–259 mcg | 0.19–0.26 mL | 8–10 units0.08–0.10 mL | 10 h |
| 75–90 kg / 165–198 lb | 234–316 mcg | 0.23–0.32 mL | 9–13 units0.09–0.13 mL | 10 h |
| 90–105 kg / 198–231 lb | 276–374 mcg | 0.28–0.37 mL | 11–15 units0.11–0.15 mL | 10 h |
| >105 kg / >231 lb | 319–431 mcg | 0.32–0.43 mL | 13–17 units0.13–0.17 mL | 10 h |
Volume column assumes a standard 5 mg vial reconstituted with 2 mL bacteriostatic water (concentration 2.5 mg/mL); insulin units shown for a U-100 syringe. Five half-lives is the conventional washout window where ~3% of peak plasma remains, a useful "next dose due" anchor for Selank (t½ 2.0 h).
