I'd just stick with vials or amps bro, if you try to save to much cash then your not gonna get good product, im not saying that sackets are not good, just saying try not to cheap out to much when it comes to injecting stuff into your body, you want to treat your body like gold, pay the extra few bucks for quality product and supplies...it will be worth it at the end...so what if it takes you a month or two longer to save for a cycle
