I used to have alot of stomach pains and issues. Ever since ive got on tren i never had Any pain, digestion issues or diahrea. I feel like it's helped my stomach and digestion a lot. Poops are always nice And solid. It does give me insomnia tho. Ive had a few cases of acid reflux during my sleep only a few times at higher dosages. Mainly from spicy food or tomato sauce. If i stay away from those im good. Also get night sweats. I never have an appetite either.
