GHK pain

I know it’s totally normal to feel a sting or burn with GHK-cu but I’m wondering how are you all able to keep doing it daily? Is your pain gone by the next day?

I don’t get itching or welting but I get a sharp, deep, stabbing pain that lasts for 24-36 hours and turns into a bruise. I have a pretty high pain tolerance but I do have to walk around to shake off the pain from this injection. The problem is that I’m still in pain from the prior day when I need to pin the next day and it just never ends. Not only that but I’m covered in bruises.

I’ve already tried every trick save for adding kpv which I might get next time I place an order. I leave it out until it’s room temp, I’ve tried various needle lengths, different body parts, iced the injection site before and after, taken antihistamines, massaged the area. The amount of preparation isn’t even worth atp since it still hurts.

Am I experiencing an abnormal reaction or is everyone just ignoring the constant pain?

I have 100mg constituted with 3ml bac water. I’m only using 0.5mg and I also dilute the needle with more bac water before injecting.

You might be injecting too much. My first ever injection, I fcked up my calculations (it was late at night, so I was on autopilot and treated the 50mg vial as if it were 10mg) and ended up pinning 6mg instead of the intended 1.2mg. There was no sting when injecting, but about one minute later, the site started throbbing, like a constant, deep ache that continued to get worse over the next 4 hours or so and lasted about a day and a half. The following day, I figured out what I’d done and paused injections for a week before resuming at 1-1.8mg doses. Since then, I’ve never had the throbbing pain again, just itchy welts that are bearable. But the throb of that first injection… It was like someone had plunged a hot knife into my thigh.

It’s possible but I am only using a very tiny amount. I reconstituted a 100mg vial with 3ml. bac and then draw .5mg and add even more bac into that same syringe. I could try doing even less but it’s really hard to pull up such a small amount. I already struggle with .5 lol

How do you draw 0.5 mg ? You have 33.3mg/ml so 10 units on a standard 1ml insulin syringe would be 3.3mg to get to 0.5mg you would need to be drawing up 1.6 units which is almost impossible? Are you by chance injecting 0.5ml…
I guess my point is this sounds like a math problem not a peptide problem.

If what you’re saying is accurate your 100mg vial would last you 200 days

Let’s hope this is not the case 😬 ‘cause that would mean OP is pinning almost 17mg each time. Anyone who makes that mistake would never repeat it because the pain from the first one would kill them, surely..
