KLOW: no pain while injecting. Does it mean it's fake?

[DarthRevan]

Hi, I got a KLOW mix, which contains:

• GHK‑Cu – 50 mg
• BPC‑157 – 10 mg
• TB‑500 – 10 mg
• KPV – 10 mg

I reconstituted it with 3ml Bac water and injected 0,11ml. It went quite smooth, and I had no reactions or pain after. This is making me skeptical because I read everywhere that the KLOW and GLOW (same but without KPV) mixes sting a lot when injecting.

Is it possible to be painless/smooth while injecting and still be the real KLOW? Or is "stinging" guaranteed, therefore meaning this is fake? At least it's blue as it should be...
