1. **Thyroxin**:
- **Source**: Thyroxin is a hormone produced by the thyroid gland.
- **Function**: It regulates metabolism, increases oxygen consumption in tissues, and promotes the oxidation of glucose.
- **Conclusion**: Since thyroxin is secreted by the thyroid gland, it is **not** secreted by the pituitary gland.

2. **FSH (Follicle Stimulating Hormone)**:
- **Source**: FSH is secreted by the anterior lobe of the pituitary gland.
- **Function**: It plays a crucial role in reproductive processes, including the regulation of the menstrual cycle and the production of sperm.
- **Conclusion**: FSH is secreted by the pituitary gland.

3. **GH (Growth Hormone)**:
- **Source**: Growth hormone is also secreted by the anterior lobe of the pituitary gland.
- **Function**: It stimulates growth, cell reproduction, and regeneration.
- **Conclusion**: GH is secreted by the pituitary gland.

4. **ACTH (Adrenocorticotropic Hormone)**:
- **Source**: ACTH is secreted by the anterior lobe of the pituitary gland.
- **Function**: It stimulates the adrenal glands to produce cortisol and other hormones.
- **Conclusion**: ACTH is secreted by the pituitary gland.

**Final Answer**: The hormone that is not secreted by the pituitary gland is **Thyroxin**.
