no joke every time i apply peptides to the muscle i am about to work out the peptides always leak out! this is my third time starting a thread about this but i just dont know. i mean i followed advice from u guys...let it warm up to room temp, keep pin in muscle for a few seconds...i dont think my muscle is tense..i jus applied to delts and my left delt had it come out. its OBVIOUSLY my fault something i do wrong i just dont know maybe the angle? but i do it in the mirror where i no its straight it....i just dont know
