Put 2 mL of bacteriostatic water into the 10 mg Kisspeptin-10 vial. That makes 5.00 mg/mL. A 150 mcg dose is then 3.0 units on a U-100 syringe.
That volume is the one that lands the draw on a syringe line, so the reading can be checked by eye. More water makes a weaker mix and a bigger draw. Less water makes a stronger mix and a smaller one. The amount of Kisspeptin-10 in the glass never changes. Only the number of marks it takes does.
Kisspeptin-10 is the ten-amino-acid working core of kisspeptin, the signal sitting at the very top of the reproductive hormone chain.
| Water added | Concentration | Per U-100 unit | Example: 150 mcg = |
|---|---|---|---|
| 2 mL | 5.00 mg/mL | 50 mcg | 3.0 units |
| 3 mL | 3.33 mg/mL | 33.33 mcg | 4.5 units |
Straight arithmetic: concentration = 10 mg ÷ water, and 1 U-100 unit = 0.01 mL. The example column shows the math at 150 mcg; it is not a dose recommendation.
Which volume to use is a practical choice rather than a dose. Pick the one that puts your draw somewhere you can actually read it on the syringe. The flags in the last column mark where that fails. “Hard to measure” means the draw is too small to judge by eye. “Won’t fit” means it is bigger than one U-100 syringe holds.
The larger kisspeptin vial contains about sixty-six weekly doses at the amount shown—more than a year—and produces the smallest syringe readings in these guides.
At the smaller listed volume a dose is three units, where a single graduation is a third of it. The larger volume helps only slightly, and it lands between marks rather than on one.
Neither water option makes this small draw easy to read because the vial is highly concentrated.
Both kisspeptin vial sizes use the same worked amount. Only the amount of powder changes, which makes the larger vial more concentrated.
Everywhere else in this family more powder means more doses and little else. Here it also means a draw nobody can measure by eye.
With no sourced window figure to make the extra doses worth having, the larger vial trades a legible reading for a count that nothing supports.
The arithmetic gives more than a year of weekly draws, but no cited source says the mixed solution remains usable for anything close to that long.
The count is arithmetic on the powder. Reading it as a duration is the specific error this vial size invites.
The table shows the offered water volumes. The calculator does the same arithmetic for any volume and any syringe, and shows its working line by line.
