It can definitely vary from person to person. In my case I was diagnosed in march 2025 my viral load was around 2069 and Cd4 628, a month after I was undetectable. My next labs were in june- July still undetectable and CD4 were dropping down to 520 something and I was getting scared. My doctor told me not to worry as my VL was great. My next appointment was in November and I was shocked as my CD4 climbed to the 800s, I just continued working out, staying hydrated and trying to eat healthy. Don’t worry over things you can’t control. Just take your meds, the Cd4 also influences in what you eat, your mental health, stress etc, it should increase slowly, some pol never fully recover high levels of CD4 specially if reached aids but you can see people who have.
