Frequently Asked
What BAC water volume gives the cleanest microdose precision for Epithalon?
A 5 mL reconstitution of a 10 mg Epithalon vial yields 2000 mcg/mL, which works out to 20 mcg per insulin unit on a 100-unit U-100 syringe. This makes targets like 250 and 500 mcg land on round unit marks instead of fractional half-units, which is the main precision constraint for microgram-scale research dosing.
How many micrograms is one insulin unit of Epithalon at this dilution?
At 10 mg per 5 mL of BAC water, each unit on a 100-unit insulin syringe (1 unit = 0.01 mL) delivers 20 mcg of Epithalon. The full draw chart for 250, 500, 1000 mcg targets is calculated on this page.
Can I use a different BAC water volume?
Yes. Larger BAC water volumes produce lower mcg/mL concentrations, which improves precision for very small doses but increases the injection volume. The alternative-volume table on this page shows what happens at 2 mL and 10 mL so the precision tradeoff is explicit. Always verify with the main Epithalon calculator before drawing.
Why does sub-100 mcg precision actually matter?
At the microgram scale, the difference between adjacent insulin unit marks can represent a 50-100% dose change. A single unit error on a target near 100 mcg can double or zero the intended dose. Some cycling protocols sub-divide the standard 5-10 mg cycle into smaller daily microdoses across 10 days.
Does the ASCEND main Epithalon calculator handle these doses too?
The main /calc/epithalon/ page handles the full dose range for Epithalon including the milligram presets. This microdose page is a focused entry point for sub-milligram research targets and links into the main calculator with the dilution pre-filled.
