My wife gave me a 25 for Deca and I thought my thumb was going to fall off. I was like WTF did you give me!!! Pulled out and I was pissing blood all over because I kept moving the puppy around to get a better grip on the plunger.
Her remark "the other ones looked like they would hurt"
I've used 25's now for a few cycles... not a problem. I usually take my time to make sure everything is going smooth into muscles (site injections). Yeah, it's not as fast. But who's in the hurry anyway??? So far worked really well for me for Deca, fina, test. And they scar less...
not like 18's I used for my first cycle...
Terumo has ultra thin walls so 25's and 27's go through pretty easily without trouble. A lot easier than BD's. I would reccommend finding some Terumo, the 25 1" work well.
