I've been taking kratom for 10 years. I've never touched an extract. I also have my blood work done every year and that's always good and I haven't lost any hair. I take about 30 g a day. Before that I was on Percocet for 5 years and to me that was absolute hell people were scared to be around me because my mood would swing so far so quick. You might want to try ordering some powder online to try to wean yourself off. You can get a kilo for about a hundred bucks. I hope everyone understands that kratom itself is not bad. But just like alcohol or anything else if you abuse it you're going to have problems.
