About

Signal TRT

Features
Read full description

Signal is a logging and reflection companion for men on testosterone replacement therapy. It gives you one private place to record your protocol, your symptoms and your bloodwork, and to see the patterns in your own logs over time. Signal organises and reflects your information back to you. It does not give medical advice, and it is not a substitute for your clinic or doctor. What you can do with Signal: - Log your protocol. Record your compounds, doses and frequencies, your injection dates, sites and notes, and keep your full history in one place. - Log how you feel. Guided scenarios help you record symptoms and day-to-day changes, from sleep and energy to mood and libido, in a structured way. - Keep your bloodwork together. Photograph a blood panel and Signal captures the values for you, or enter them by hand. Each marker comes with a plain-English explanation of what it is, and your results are organised so you can see them over time. - Add context from your fitness tracker. With your permission, Signal can bring in sleep, heart rate variability, resting heart rate and activity to sit alongside your logs. - See written reflections of your own data. Signal produces clear written summaries from what you have logged, so you can step back and see the bigger picture. - Prepare for your appointments. Turn your logs and bloodwork into a report you can take to your clinic or doctor. Signal Core and Signal Pro are available, with a free 14-day Pro trial. Signal is built for adults aged 18 and over who are on TRT or actively considering it. Important: Signal is a logging and reflection tool. It does not provide medical advice, diagnosis, treatment or clinical interpretation, and it is not a substitute for advice from your clinic or doctor. Always speak to a healthcare professional about your treatment. Privacy Policy: https://signaltrt.com/privacy Terms of Use: https://signaltrt.com/terms
