I've used a little of Negma's Parabolan from way back long after it had expired. Was some real good stuff, it was actually the first tren product I had ever used. I think the reason it is still so highly talked about is the times it was in. Tren now a days is a dime a dozen, especially with the ability to make your own. Back then, it was only this and there was nothing like it. Kind of like a hot French chick that moves to town, puts out, then moves away all of a sudden. Then 20 equally hot American chicks move to town and they are all whores with big titonas. Thats my analogy for the day. Ur welcome!
