peptides leaking out after application

after applying with a slin pin to my tricep i realized sum of the peptides leaked out with a little blood
this is the second time it happened to me on my right tricep wat do u think the problem is?

The muscle is tense?

did you do this post workout?
if so the muscle is probley engorged with blood..... nxt time wait a bit before application

are you applying anything else to that area?

thanks for the replies bros i actually applied it about 30 minutes or so after the workout like i usualy do so im assuming it shouldnt be that engorged with blood and im not applying anything else to it. it must be how im doing it thats wrong i just gota figure it out. its the only second time happening over 2 weeks of applying to various places such as traps tri's bi's shoulders n calves its just the specific right tricep that its happnend too. just a little mad since i dnt want to waste any of it lol not really scared as to it being bad to my body
