What is Boys Butter?
Boys Butter is a grass-fed tallow balm built for the skin that works hardest -- groin, inner thighs, underarms -- the areas that take the most friction, heat, and moisture every single day.
Tallow's fatty-acid makeup sits close to your own skin's oils, so it absorbs instead of sitting on top, and helps your skin hold onto its own natural defenses rather than covering the problem with powder or menthol.
How to use
Morning: a small amount on clean, dry skin each morning -- groin, inner thighs, anywhere friction tends to build.
Evening: apply before bed to let it work overnight, especially after a long day or post-shave.
Sport: apply before training, long days on your feet, or anything high-friction.

Why Tallow Works
The short version, without the hype.
Close To Your Own Skin
Human sebum and rendered tallow share a similar fatty-acid makeup, which is part of why tallow-based balms tend to absorb rather than sit on the surface.
Naturally Carries Vitamins
Grass-fed tallow naturally contains vitamins A, D, E, and K -- the same fat-soluble vitamins your skin already uses.
A Barrier, Not A Mask
Unlike powders or petroleum sticks that sit on top, tallow's fat content helps replenish the skin's own lipid barrier.
Simple, Not Synthetic
No menthol, no numbing agents, no synthetic fragrance -- just fats and essential oils your skin can actually process.
Cosmetic benefits only -- Onyx Boys Butter is not intended to diagnose, treat, cure, or prevent any medical condition.

Frequently Asked Questions
What makes this different from powder or anti-chafe sticks?
Powder absorbs moisture but doesn't heal anything. Sticks create a temporary, usually petroleum-based barrier that wears off fast. Boys Butter rebuilds your skin's own barrier with fats it already recognizes -- it absorbs deep and lasts all day instead of just masking the problem.
Does it help with stretch marks?
Many guys use it daily on stretch-mark-prone areas -- thighs, hips, upper arms. The fats in tallow help keep skin supple and well-hydrated, which can improve the look and texture of stretch marks over time with consistent use. It won't erase them, but it's part of a real skin-care routine instead of a one-time fix.
How long does a jar last?
With daily use, a 2 oz jar typically lasts 6-8 weeks. A little goes a long way.
Is it good for sensitive skin?
Yes -- it's built for skin that's already been irritated by everything else. No menthol, no numbing agents, no synthetic fragrance, no alcohol. Five clean ingredients your skin recognizes.
Will it feel greasy?
No. Tallow's fatty-acid profile is close to your own skin oils, so it absorbs fast instead of sitting on top.
Can I use it after shaving?
Yes -- post-shave is one of the best times to apply. It calms razor burn and helps reduce ingrowns.
What if it doesn't work for me?
You're covered by a 90-day money-back guarantee -- no questions asked.
