Did I buy a dud dose from SwissChems.is?

Hello.

I have injected 0.250mg every second day for 14 days. I've layed in the sun for about 15 minutes every day (summer in australia).

But my skin tone is not really any different. Not really any tan at all, maybe a 0.75% difference (I thought that would just be from the sun)

Is this normal for a pale skin irish lady? I feel like i have bought some empty useless peptide from SwissChems.ie
