A private calculator hub for steroid half-lives, ester weights, injection schedules, lab-unit conversions, body composition, and post-cycle timing.

Landing page captured for the 2026-08-28 issue.

Field notes

The homepage exposes seven browser calculators, including a plotter that accepts compound, dose, frequency, and cycle length before charting active milligrams by week. It also lists half-life references such as testosterone enanthate at 4.5 days, boldenone undecylenate at 14.0 days, and oxandrolone at 9 hours. Guides extend beyond arithmetic into bloodwork, injection technique, detection windows, liver toxicity, and post-cycle timing.
