it will definately inject the oil but i will be more painfull and cause more scarring than 23 or 25 guage .

how much more scarring? im new to injects i no all where and all to inject and im starting out at 250 mg of sus every 5 days with 30 mg of dbol a day, i might just run the test byitself then throw the tabs in later a few cycles later.But yeah i got the needles and was like DAMN those mother fuckers r huge LOL.

you can draw up the oil in that 21 guage harpoon lol and then just switch to a new smaller guage and sharper needle [ sharper since you didnt use it in a amp or vial ] .
i reccomend just ordering the needles to go with the syringe and needles you allready have .

my mistake the syringes say 21G on the back of the package and have the 21G needled already in them, but my other package of just needles say 23G on the back of them.Will these 23G needles fit my 21G syringes safely and not leak an test ?

I would go with 25g. send that shit back
