It doesn't matter if your dbol is from Thai, Russia, or Bulgaria... if you're prone to hair loss there is a chance that Dbol could speed up the process. Same goes for Winny.
If you have a predisposition to MPB,then ANY d-bol,or any androgen in general will accelerate this process.Deca would be your best choice if concerned about keeping your hair,or using nizoral shampoo with any future anabolic runs.
thanks huck.. i just read some posts where guys who actually were very prone to hairloss.. and used winny and shed like crazy, then used d-bol and no hairloss occured... i had a friend who used tais at 15 mg ed and gained 20 lbs which he kept all....so i will keep my dose at 15-20 mg ed for 5 weeks
