Tools & Calculators

Explore volume arithmetic from entered amounts using a U-100 scale.

Print a clear label for a reconstituted vial — concentration, dates, notes.

Convert insulin units, mcg/mg, mg/kg, and HCG IU.

Pick a gauge and syringe from the dose volume and fluid type.

Log injections and rotate sites to protect tissue health.

Log labs over time and trend against reference ranges.

Check your stack against a curated compound × supplement/Rx interaction dataset.

Symptom/E2 scenarios → the category of approach (reference, not dosing advice).

Symptom → likely cause, suggested bloodwork, and when to seek care.

Review PCT evidence and prepare for a clinical discussion of recovery.

Visualize compound concentration over time with harm-reduction overlays.

Overlay pharmacokinetic curves and compare compounds side by side.

Inspect sampled extrema and the pre-next-dose value within one modelled interval.

Explore a single-dose model decline relative to its sampled peak.

Understand analytical detection, study limitations and current anti-doping requirements.

Convert between ng/dL, nmol/L, pg/mL for total and free testosterone.

Calculate free and bioavailable testosterone using the Vermeulen formula.

Explore available testosterone models and their source and calibration limits.

Compare editable assumptions on a relative scale, without claiming human blood concentrations.

Convert esterified mg to actual free testosterone — how much of the vial is hormone vs ester.

Vial size, price, and dose → true cost per week, month, and cycle for a multi-compound stack.

Calculate your basal metabolic rate (Mifflin-St Jeor).

Find your total daily energy expenditure and maintenance calories.

Estimate body fat percentage using the US Navy tape method.

Calculate calorie deficit targets for fat loss.

Calculate calorie surplus targets for muscle gain.
