I have used it. Its the real thing i believe those are the 5cc vials. The only problem with EC is they are hit and miss. Sometimes there stuff is really good other times it can be a little underdosed.
The first injectable cycle i ran was Tren and Eq and my strength sky rocketed. I just started a Tren enanthate,Sust250 and Eq stack this week. I think if you want size and strength test is King. If you want strength good size hardness and to stay pretty lean Tren is the way to go.
