CJC/IPA reaction after weeks of no reaction- is this normal?

[Lady Hamilton]

Hey, I’m after some advice..,
I started CJC/IPA a few weeks back, I’ve been absolutely fine and all of a sudden, I’m reacting with itchy bump (looks like a big bite) which lasts about 4 days.
So I mixed another vial, the same reaction. I just don’t understand.

Has anyone experienced this?

Do I give up or lower the dose?

Same happens to me. Was fine for awhile but now I get the small itchy welt that last a couple days so I stopped taking it. I don't mind a reaction like I get from MOTS-C where it's red and itchy for maybe a half hour. The multi-day itchy spot isn't worth it to me. A quick google search says apparently the GH peptides tend to be the cause. It's a histamine response from mast cell activation at the injection site.

Are you using a pen or syringe? What size needle? I test different needles from time to time and am finding that I have fewer ISR’s with a 32gx6mm pen needle than with a 32x4mm needle. I also get more of a flush with CJC/IPA - which may or may not mean i am getting better/faster uptake with the slightly longer needle. But definitely less bleeding and fewer itchy bumps.

My reactions from CJC/IPA have been all over the place. Never had anything that lasted days and nothing that was too much for me. Now my son just recently had an itchy bump last for about three days. First time that had happened to him.

I just have always seen it as part of the deal.

The same thing happened to my rat with both CJC No DAC/IPA and also MOTS-c. For a week or two nothing. Then itchy red spot that lasts 2-3 days usually. It caused him to stop MOTS and he's powering through the CJC/IPA until my cycle is over.
