I think alot of the low doses come from lack of availabilty and prices. In 1993 100 tabs of russian dbol at my college went for $125. Deca was $300 for 50mg/50ml. Anyway, people couldnt afford much and alot of the info comes from these people. The rumors just spread over time. Just like everyone always wanting deca or wintstrol because its so safe. Well winny used to only come in 2mg tabs! So, taking 50mgs ed was hard on the wallet. Look at the old anabolic reference guides. They suggest like 5-10 tabs a day. Well thats only 20mgs, thats why it was safe!
