Helix Log by Helix Horizon Labs

Every vial,
worked out.

Helix Log is a reconstitution calculator and dose log. Enter what is in your vial and what you mix it with, and it shows the units to draw on your syringe. Then it keeps track of your schedule, your vials and every dose you log.

  • Now available on Google Play; iPhone coming soon
  • Made for folding phones too
  • Your data stays on your phone
Helix Log's Calculator: 5 mg in the vial, 1.5 mL water added plus 0.5 mL acetic acid, 250 mcg per dose on a U-100 syringe. The draw is 10 units, 0.1 mL at 2.5 mg/mL, 20 doses per vial.

Your numbers in. A clear draw out.

From the vial
to the log.

Helix Log does the arithmetic that sits between a vial label and a syringe, then keeps the record. It does not tell you what to take or how much. You enter the peptide, the amounts and the schedule; it works out the rest from those numbers.

How the numbers work

Plain arithmetic,
in the open.

Every number Helix Log shows comes from the numbers you type, worked the same way each time. Here is exactly what it calculates.

From vial to draw

The calculator adds up the liquid in the vial, finds the strength, and turns the amount per dose into a volume and then into syringe units:

total liquid = water added + additional liquid

concentration = peptide in vial ÷ total liquid

draw (mL) = amount per dose ÷ concentration

units = draw (mL) × syringe units per mL

Doses per vial counts whole doses only: the peptide in the vial divided by the amount per dose, rounded down.

Syringe scales

  • U-100: 100 units per mL, up to 100 units.
  • U-50: the same 100 units per mL scale on a half-mL barrel, up to 50 units.
  • U-40: 40 units per mL, up to 40 units.

So the same 0.1 mL reads 10 units on a U-100 or U-50 syringe and 4 units on a U-40. Pick the syringe you actually use, and the units follow it.

Units of amount

Amounts in mcg and mg convert at 1 mg = 1,000 mcg, with the vial entered in mg. IU stays IU: in IU mode the vial is entered in IU, and Helix Log never converts IU to mg, because that conversion depends on the substance.

Blends and working backwards

Blend takes two to six peptides mixed in one vial and a draw in units, and shows how much of each peptide that draw holds and how many draws the vial gives. The water solver starts from "this dose should be N units" and works out how much water to add, allowing for any additional liquid.

Supply, from your own log

Each dose you log comes out of the vial it was drawn from. What is left, divided by the amount per dose and rounded down, is the doses left. Laid against your schedule, that gives the day the vial runs out and, for a protocol with an end date, whether the open and unopened vials cover it or how many vials short you are.

What it won't do

Helix Log has no list of compounds, suggests no doses or schedules, and links to no sellers. You type your own peptide names and amounts. Its results are only as right as the numbers entered, so check them against the vial label and your syringe before drawing. It is a calculator and a log, not medical advice. For what research does and doesn't show about peptides, see our Peptide Science page.

Your data stays yours

Kept on your phone.

  • Protocols, vials and your dose log are stored on your device. Helix Log has no account, no analytics, no advertising and no server of its own, and sends nothing to one.
  • Reminders are notifications scheduled on the phone itself.
  • Back up everything as a file, or export your dose log as a spreadsheet (CSV), and share it only where you choose. A backup file can be loaded back in, adding what the phone is missing.
