Particle peptides vial has arrived

so I have a couple upcoming exams this year and I wanted to find a spot to order Semax from. I ended up finding a website called particle peptides and btw the reason I choose them it's because I cannot pay with bitcoin, so I just had to find a website where I could buy with card. The package arrived very fast, I'm in eu btw, and yeah I'm not sure if it's under dosed tho because it seems like there's very little powder in the vial. Anyways, I'm not sure if I will order from them again because I think I found a way to pay with bitcoin and I found a cheaper/better supplier.
