27 gauge? You can try, but I'm not sure if it would. It's 100mg per ml so that means less injection volume...I'd at least use a 25, if not 23 gauge pin.
I shoot oil-based stuff into my triceps with a 23 gauge...Doesn't hurt at all.
I wouldn't try it (Ttokko) with the 27 gauge. A 23 would be safe and IMO it doesn't feel any different going in. The Stanol V injectible is a great value, IMO also.
BTW, AJC, excellent site; updated, current & informative, I am getting alot out of it.
Mine clogged a little with a 27 gauge. I have more pain tolerance than patience, but actually, I really dont feel any pain with the needle 23 g or otherwise. Then again, I haven't tried bicep injections yet...
