Expression: Core

by toastydoll

Expression: Core adds hormone replacement therapy mechanics, potion effects and dosage screens to Minecraft on NeoForge, with the mod's own player model effects.

NeoForgeClient and serverAll rights reserved1.21.1

What it does

Players take hormones such as estrogen, testosterone, progesterone and spironolactone, and the mod tracks each dose through a GUI that shows how much has been taken. Pills, gels, injections and implants are all patched in as ways to administer them. Raising the dose count to 10 or more produces a euphoric state, and the mod adds new potion effects, including a soft falling effect and a gender affirming potion form.

Gender presentation is handled through Wildfire's Female Gender Mod, which Expression: Core uses for its player model effects. The mod also adds a few unrelated extras, such as a dream block, a dashing mechanic and a music track inspired by Celeste. Client and server both need the mod, and it is released under All rights reserved, so it is not open source.

Required dependencies are Curios API and Female Gender Mod. Five catalog mods depend on Expression: Core, including Create: Expression, Expression: Industry, Expression: Community, Expression: Easy Recipes and Abel's Expression Recipes. Files are published for NeoForge 1.21.1, with the latest, 3.0.7, dated 2026-09-25.

Key features

  1. Hormone items

    Estrogen, testosterone, progesterone and spironolactone are available as items that can be taken in several forms.

  2. Dosage screen

    A GUI shows how much of each hormone has been taken, so players can check their current amount.

  3. Euphoric state

    Raising the dose count to 10 or more makes the player euphoric, and the effect is tied to the dose total.

  4. Potion effects

    New potion effects include a soft falling effect and a gender affirming potion form.

  5. Dream block and dashing

    A dream block, a dashing mechanic and a music track inspired by Celeste add non-hormonal gameplay.
