Amps are a pain in the ass and this is why.
1) Sometimes the Ampule head shatters into a million pieces and you cut yourself.
2)Juice can spill out of the amp.
3) you cant create a vacuum.
4)when you're sucking out the last juice on the bottom you start sucking in air and it takes forever to get the last amount in your syringe.
How come when im breaking off the amp head its shattering into a bizillion pieces??
I paid 18 bucks an amp for 100mg Schering Primo Depot.
