HCG Tracker 4.8

Track Your HCG Protocol

Log every IU dose, calculate syringe draws from your vial concentration, and coordinate HCG with your TRT protocol on one timeline.

Free to download. Free for your first compound.

HCG is tracked in IU per injection. Standard TRT-support dose: 250 to 500 IU, 2 to 3 times weekly, subcutaneous. Reconstitute a 5,000 IU vial in 5mL bacteriostatic water to get 1,000 IU per mL. At that concentration, 250 IU is 0.25mL (25 units on an insulin syringe). Track: dose, injection day, vial concentration, reconstitution date.

Schedules, cycles, calculators, and inventory in one place

Stay on top of your dosing schedule.

Every schedule you need

Daily, weekly, EOD, custom, as-needed. Stay consistent with smart reminders for every cadence.

Cycle management

Set your cycle duration and get alerts when it's time to cycle off, take a break, or restart.

Reconstitution calculators

Reconstitution, reverse BAC, TRT oil, and intranasal. Regimen handles the complex math, so you don't have to.

Inventory tracking

Your weight has been dropping faster since your dose went up to 7.5 mg.
Your joint pain has eased over the three weeks you've been on BPC-157.
Your hematocrit has crept up three draws in a row: 46, 48, now 50%. It's the number TRT docs watch closest.

Why tracking HCG matters

IU calculator built in

Enter your vial IU count, water volume, and target dose. Regimen calculates the exact syringe draw - no more mental math or triple-checking.

Vial expiration tracking

Reconstituted HCG degrades. Regimen tracks when you mixed it, how many doses remain, and alerts you before it expires.

Protocol coordination

Running HCG alongside TRT? Regimen schedules both independently and shows your full protocol on one timeline.

What Regimen Tracks for HCG

  • Dose amount (IU), timing, and injection site
  • PK curves showing estimated HCG blood levels
  • Vial reconstitution details and expiration tracking
  • Fertility markers and symptom logging
  • Weight and body composition trends
  • Energy levels and mood
  • Sleep quality and duration
  • Coordination with TRT injection schedule
  • Lab work dates and notes
  • HCG (human chorionic gonadotropin) is the second compound most TRT users find themselves running, and it is the one most people screw up tracking. Doses are in IU (international units), not mg. Reconstitution math is different from peptides. And the protocol overlaps with your testosterone schedule in ways that matter. Here is how to actually track HCG so the math is right and the protocol stays consistent.

Frequently Asked Questions

What is the difference between IU and units on an insulin syringe?

+

IU stands for international units, the actual dose of HCG. Units on an insulin syringe are volume markings (1 unit = 0.01mL). At a 1,000 IU per mL concentration, 250 IU equals 25 units of volume. The two numbers are not interchangeable.

Can HCG and testosterone be injected in the same syringe?

+

Technically yes for subcutaneous use, but it is not recommended. Separate injections let you adjust dose timing for each compound independently and confirm each was administered correctly.

How long does reconstituted HCG last?

+

30 days refrigerated, kept cold throughout. Some studies suggest 60 days at lower concentrations, but stick with 30 days for confidence in full potency.

What time of day should I inject HCG?

+

Most users inject in the morning for consistency. HCG's half-life means timing within the day matters less than consistency week to week. Set a recurring schedule and stick to it.

Do I need bacteriostatic water or sterile water for HCG?

+

Bacteriostatic water. The benzyl alcohol in BAC water prevents bacterial growth during the 30-day usage window. Sterile water has no preservative, which would mean the reconstituted vial expires within hours.

What to track on an HCG protocol

  • IU per injection (the number that actually matters)
  • Vial concentration in IU per mL after reconstitution
  • Reconstitution date (HCG degrades, 30 days refrigerated maximum)
  • Injection day (coordinate with TRT injection day, see below)
  • Testicular size or firmness (the subjective indicator most TRT-on-HCG users monitor)
  • Mood and energy (HCG influences both)
  • For fertility goals: sperm analysis every 90 days

Common mistakes when tracking HCG

  • Confusing IU with units on an insulin syringe. They are different. 250 IU at 1,000 IU per mL concentration = 25 units of volume.
  • Forgetting to log the reconstitution date. HCG loses potency after 30 days refrigerated, faster if it was left at room temperature.
  • Injecting HCG on the same day as testosterone. Coordinated spacing (HCG midway between TRT injections) gives steadier signaling.
  • Skipping the testicular measurement log. For TRT-support HCG, this is the indicator most users actually care about.
  • Not logging dose changes when your protocol evolves. You need the history to correlate effects.
