“Finally an app that speaks my language. Not a pill reminder. Not a bro-science bodybuilding tracker. It just works.”

Stay dialed in.
Without thinking about it.
Himcules is the first injection tracker written for men on TRT — not bodybuilders, not pill-takers. One tap to log. A quiet countdown that knows your protocol. And a serum-T curve that finally explains why Tuesday felt off.

Why Himcules
Generic pill apps don’t understand you.
Bodybuilder trackers aren’t built for you.
Abandoned clinical tools don’t even log.
Himcules is none of those.
Speaks your language.
Pin. E3.5D. Trough. Dialed in. Cypionate. The vocabulary is already yours — the app just uses it correctly.
VocabTRT-native
Serious, not sterile.
No lab-coat condescension. No PED stigma. A rigorous tool that respects you as an adult on a prescribed protocol.
ToneRespect · not policing
Private by default.
No account. No cloud. No injection data on our servers. Your protocol lives on your phone and only your phone.

What you get
Six moves that make dialed-in the default.
Every feature earns its place. Nothing is here for decoration. This is what we ship — and intentionally, what we don’t.
01Countdown
Never wonder if today is pin day.
A 180° arc on your home screen answers the only question that matters. Teal when you’re ahead of schedule. Amber when you’re due. Red when you’re overdue — with a pulse. Glance and go.

02One-tap log
Pin. Done. Next.
Every log is one tap. The app pre-fills dose, volume, timestamp, and the correct next site from your rotation. Two seconds from cap-off to confirmation. Haptic on success.
- Time to log
- ~2 seconds
- Fields
- 0 required (all pre-filled)
- Confirmation
- Haptic + optional confetti

03Rotation
Six sites. Zero memory required.
Deltoids, glutes, quads — left and right. Pick your preferred subset; the app rotates through them in order after every log. Scar tissue, PIP, and lipoatrophy don’t stand a chance.

04PK curve
See your levels between labs.
A mini serum-testosterone curve on the home screen uses peer-reviewed population-PK models for all five major esters. Not a replacement for bloodwork — an honest read on the rhythm between them.

05Streak
Life happens. Your streak survives.
Most trackers punish a single late log. Himcules gives you an automatic Streak Freeze — one grace per 30 days — for late logs within 48 hours, unlocked once you have 7 pins to protect. Consistency without the fragile.
- Grace window
- 48 hours
- Cooldown
- 1 freeze per 30 days

06Energy
One tap. One truth.
A daily one-second “How’s your energy today?” log pairs subjective state with injection timing. Over weeks, the pattern reveals itself: the day-4 dip isn’t you — it’s the protocol.

iOS only.
The only real
Android TRT tracker.
Four of the top five TRT trackers are iOS-only. Himcules shipped on both platforms from v1.0. Same one-tap log. Same PK curve. Same local-first architecture.
If you’re on Pixel, Samsung, OnePlus — this is the first time you’re not an afterthought.

What users say
From the men actually pinning.
“The rotation logic alone is worth it. Zero thinking required — it just tells me which side and I pin.”

“The PK curve made my trough/peak timing finally click. Explained my energy dips better than my doc did.”

Under the hood
The science
most trackers skip.
A population-PK model, tuned per ester, based on peer-reviewed literature. Clearly labeled as estimate. Never promoted as a replacement for bloodwork. Respect, not overreach.
