Could my peptides be fake?

Ive been in reta, ghkcu, kpv for about 4 weeks now
Ghkcu 3mg, kpv 0.5mg,
Reta
wk 1: 1mg
Wk 2: 2mg
Wk 3: 3mg
Wk 4: 5mg
Ye ik i probably increased the dose too quickly but im basically not feeling anything at all, no side effects no appetite supression nothing..
As for KPV i feel my body is instead getting more inflamed, im definitely in a calorie deficit i eat home cooked meals and tracked everything and i have not lost any weight at all and it makes no sense infact i gained 1-2kg... I do not have PCOS or hypothyroidism cld it be other underlyimg issues at play or are my peptides just not that pure. Ye 4 weeks may be too early to tell but i feel like i should at least be getting better the wks go by but i js feel more and more shitty. I havent been able to sleep well but i have been drinking 3l of water everyday i js really need some advise. It js makes zero sense how im in a deficit, i walk alot and gym yet the scale increased...
