I'm on tdf since almost 2 years and I've gained muscle in a meantime and my weight went up around 7kg.
I do hard weight/cardio trainings 4 times a week. I take protein supplements and 2000-4000 IU of D3 during autumn/winter.
Sir same with me. 3 months viread. Im losing weight and muscle mass.
weak bones are due to hbv, hbvers have life long vit d deficency which lowers immune system and makes oseoporosis
as to weight loss thet is beneficial for the liver, bmi between 20-22 are the best for the liver and also longevity, big muscles masses dont go well with liver both for hbvers or hbv negative people
if you do want muscles you may try heptech products and contact hepatitistechnologies, i think todd schnider also keeps good shape muscles so he might have good tips on diet and supplements, he had advanced cirrhosis from hbv+hcv and regressed cirrhosis by heptech products only (hbv+hcv has no therapy)
You should check your Vit D3 level. Test name is " 25OH Vitamin D3 "
Depending on how low your vit d3 level is, you can take vit d3 5000iu or 10,000iu. I am on 8000 iu vit d3 at the moment.
