Importance of Starting HRT Early
Starting hormone replacement therapy (HRT) at a younger age can significantly impact the physical and emotional aspects of transitioning. Many individuals express regret for not starting sooner, as earlier initiation can prevent further masculinization and allow for more effective feminization. For example, one user shared, "At 18 not all the bone plates have fused. For example, the hip bones don’t fuse until around 25. I started at 19 and noticed growth in my hips some of which I think came from bone growth." – basedboymoder source [citation:4de67ce8-b4c8-4d77-b340-c369ef801ab4]. This highlights the potential for more significant physical changes when starting HRT earlier.

Psychological and Emotional Benefits
The psychological and emotional benefits of starting HRT earlier are profound. Many individuals report feeling more centered and aligned with their true selves, which can lead to improved mental health and overall well-being. One user shared their experience of starting HRT later in life, stating, "I feel better, happier, more centered on HRT and presenting MTF/NB than I ever did as a man." – DevonReally source [citation:b7bf44d9-81a8-4711-84e5-9d37a9261caf]. This underscores the emotional relief and happiness that can come from aligning one's physical appearance with their gender identity.

Challenges of Starting HRT Later
Starting HRT later in life can present challenges, such as the difficulty of reversing years of masculinization. Many individuals express regret for not starting earlier, as they face limitations in physical changes like hip growth and facial fat redistribution. One user shared, "I started at 36 and I've had great results, but even then, it would've been much more effective if I could've started earlier." – Ok-Baker7413 source [citation:ccde793d-29a6-4e0d-8806-742d01dc3be4]. Despite these challenges, starting HRT at any age can still lead to personal happiness and fulfillment.

Regret and Encouragement to Start Sooner
Many individuals who started HRT later in life encourage others to begin as soon as they are sure of their identity to avoid future regrets. One user emphasized, "As someone who started at 35, I'm constantly encouraging trans people to start HRT ASAP. I'm very happy that I finally started, but if I could go back and start 20 years ago, I absolutely would." – ReginaSpektorsVJ source [citation:f29be8c8-5768-4691-9d35-ec28851c54bc]. This highlights the importance of taking action when one is ready to embrace their true self.

Conclusion
Starting HRT is a deeply personal decision that can have significant physical and emotional benefits. While starting earlier can prevent further masculinization and allow for more effective feminization, beginning HRT at any age can lead to personal happiness and fulfillment. The shared experiences emphasize the importance of taking action when one is ready and informed, to live a life that aligns with their true identity.
