Reconstitution chart: 5 mg vial
| BAC water added | Concentration | Draw for 100 mcg dose | Draw for 250 mcg dose |
|---|---|---|---|
| 1 mL | 5,000 mcg/mL | 2 units | 5 units |
| 1.5 mL | 3,333 mcg/mL | 3 units | 7.5 units |
| 2 mL | 2,500 mcg/mL | 4 units | 10 units |
| 2.5 mL | 2,000 mcg/mL | 5 units | 12.5 units |
Draws are U-100 insulin syringe units (100 units = 1 mL). Formula: dose in mcg ÷ (vial mcg ÷ water mL) × 100. The calculator above handles any other combination.
About DSIP
DSIP stands for delta sleep-inducing peptide, a small neuromodulating peptide first isolated from the blood of sleeping rabbits in the 1970s. Research has examined its effects on sleep architecture, stress hormones, and circadian rhythm, with mixed and inconsistent results across decades. It has no regulatory approval anywhere, and the human data is thin and old. What circulates today is research-grade powder.
Community protocols typically discuss 100 to 250 mcg in the evening before sleep, the timing that matches the studied purpose. Note the unit: micrograms. A 5 mg vial holds 5,000 mcg, so even at 250 mcg per dose one small vial covers twenty injections. Entering a DSIP protocol with the unit set to mg rather than mcg produces a 1,000x error, which is why this page defaults to mcg and warns on suspicious values.
Because the doses are small relative to the vial, the water you add is about readability. With 1 mL of BAC water in a 5 mg vial, a 100 mcg dose is only a 2 unit draw, too small to measure honestly. Stretch the water to 2.5 mL and the same dose becomes 5 units. The calculator flags any draw under 3 units so you never have to eyeball a sliver of a syringe. Keep the reconstituted vial refrigerated and use it within the window your source specifies.

Stop gambling on where you buy your peptides.
The calculator tells you how much to draw. The Verified Buyer's Manual tells you how to source the peptide itself without getting scammed or shipped underdosed product. Trace any compound back to the lab that made it, read a Certificate of Analysis and catch a fake, grade any seller before you pay, and price it right. A repeatable system, not a list of names that goes stale.
- How to read a lab report (COA) and spot a faked or misattributed one
- Source tracing and the referral route: find sellers worth trusting
- The vetting grid: a yes-or-no scorecard for any seller
- Real cost-per-mg math, plus what domestic stores and direct sellers really charge
- When a paid lab test is worth it, and how to filter every vial
- Payment, shipping timing, stocking up, and the first 72 hours after a package lands
