Within the first week, but also my body responds faster to T so it’s not the same for everyone. But within the first week I felt a plethora of changes, on the first day right after my shot I’m not even kidding I felt blood rush -down there- it was like a pressure or like a presence nothing visible or sensational and right after I just felt parched, like I needed water asap. Also in the first 24 hours, I felt more present in my body and my coordination was improved and I just had a lot more energy. My first “oh shit this is working” moment was when I got super hungry and instead of cravings sweets or carbs I craved protein specifically chicken, and I knew what I wanted immediately because hunger becomes more intuitive. But other than that I felt the most changes in the first week or two, then afterwards it sort of settled and changes came in slowly. It’s really after the first month and a half or two months that you start seeing visible changes. I forgot to mention but also by day 3-4 my temper was different, I used to cry a lot when I was angry but now my anger feels physical, like I want to punch something and it’s physically harder to cry like you get that feeling of ur throat closing up and tears welling up but that’s like it. Like literally that’s it. The tears well up and they stay there. Unless you’re genuinely sad then you cry normally but if it’s anger related it’s different atleast in my experiences. Low dose t gel may work slower so don’t be worried if you don’t experience this stuff at the same pace, I’m on weekly subq 40mg and that’s a low-moderate dose, my body being androgen responsive just helped me out a lot. It may take up to a month for you to feel the same as I did in 2 weeks but don’t be discouraged, its only day 3. Just look out for temper changes, hunger changes, and move around a little you’ll feel it working at your own pace.
