for me its about the test, when i was 18-19 i lived a full bodybuilder life had very high test levels natty, and i can remember jus rubbing my head over the table and hair would litterally fall right off, and i mean a good amount, now that i dont train as hard and not living a complete bb lifestyle = less test i no longer shed like a dog. thats me and thats y i will never do roids id b bald in 3 cycle.
