Playful Doodle Logo: HRT & JiuJitsu

I’m launching a hormone-replacement therapy brand that has its roots on the Jiu Jitsu mat, and I want the logo to feel as energetic and irreverent as that mix sounds. Think loose, doodle-style line work that looks hand-drawn rather than polished, yet still refined enough to live on a website header, rash-guards, prescription packaging, and social media avatars.

The concept calls for both worlds to be visibly intertwined—for instance, a flowing Jiu Jitsu belt looping through a stylised hormone molecule, or a playful hormone vial throwing a belt knot. I’m open to your twist on the imagery as long as the final mark instantly reads “HRT meets Jiu Jitsu” and stays light-hearted rather than clinical.

Please draw freehand (Procreate, Illustrator’s pencil tool, or your favourite tablet setup) and then convert the illustration to clean, scalable vector paths. Colour can stay minimal—two or three tones max—but the line art must hold up if the logo is reproduced in one colour only.

Deliverables
• Editable vector file (.AI or .EPS)
• Transparent PNG & high-res PDF
• Monochrome and full-colour versions
• Small usage guide noting colours and safe-space

I’ll give fast feedback during sketch and refinement rounds so we can land on a mark that feels authentic, playful, and ready to roll across all brand touchpoints.
