I take a 50 mg vial of the copper peptide, add 1 ml bac water, then mix it into a hyaluronic acid serum with ceramides. Look into that approach before committing fully.

Same here. I added one more unit of bac water to the syringe, let it reach room temperature, and used numbing wipes. Still a little sore though.

My upper thighs look like paintball targets. I did six days on one version before switching to the current blend and reactions are milder now. A couple shots had zero reaction, so I'm trying to pinpoint what works. Since I'm a side sleeper, tomorrow's spot might need to be further around, though my partner isn't eager to help with that. I'll try the ice pack too.

Yeah, right now I'm using 15 units of the blend then adding another 25 units of bac water and it still stings like a stab. That user has some good suggestions, so I'll try the ice pack and percussion massager if I can find it.

Use the topical version for the face cream instead.

I found something that works for me and wanted to share in case it helps others. I had quit the copper peptide because of skin issues and welts that lasted days and flared at night. I suspected cortisol and histamine played a role. With a new vial from the same batch I changed two things and reactions are now minimal. I dilute more than usual, fifteen units copper to thirty-five units bac water, and I avoid fat tissue, sticking to lean subcutaneous spots. Those clear faster, probably due to better diffusion. I've seen the same with other irritating compounds. It's made a real difference for me.

Tried intramuscular with the copper peptide and it also produces little to no reaction. I was worried it would hurt more but it didn't.

I got the basic form and it removes all discomfort from the copper version. Extra bac water helped before, and adding epi or lido made it tolerable but left a dull ache later. Using a three-to-one ratio of copper to basic, with no additives or wipes, eliminated burning, stinging, and delayed pain completely. Responses vary, but if other methods haven't worked it's worth trying. Discussions on why it helps exist on certain forums.

Thanks for sharing your results. My own reaction is just mild itching on and off for a day plus a raised red welt that bothers me cosmetically. I only use outer thighs and they look rough now. I was thinking of trying the copper peptide alone today without the other one first to see if fewer pokes reduces the welt. I've seen some comments that the other peptide might be mildly inflammatory even while helping healing. Does the basic form reduce the benefits of the regular one?

It's strange that some say the other peptide has inflammatory effects since it's known for anti-inflammatory benefits and helps me with aches. It didn't reduce my copper peptide issues much but I used it anyway for its own effects and recently cycled off. The basic form shouldn't cancel out the benefits of the copper one. There's a thread on one forum discussing the blend.

I add one milliliter of two percent lidocaine per fifty milligrams of the copper peptide. I get a red spot but no itch or pain. My dermatologist uses less lidocaine for skin samples so I'm well under that amount.

Over time the sting has dropped to almost nothing. Glad, because it used to hurt badly at first.

Right, I forgot I'm not on that forum. I think the comments about the other peptide possibly being too much came from some Reddit users in long covid or autoimmune threads.

SharpHarbour71archiveApr 13

The key for me has been heavy dilution, ten milliliters bac water per fifty milligrams copper peptide, and that stopped reactions completely.

I only went to six milliliters bac for my sixty milligram vial. For the next one I'll increase to a ten-to-one ratio and see if that helps.

It's worth joining that forum. Here's how: follow the info thread on the glp1forum, spend a couple weeks reading and participating to unlock full access.

Draw the copper peptide into the syringe then add five to seven hundred fifty micrograms of the other peptide. That mix helps a lot. My partner is very sensitive to redness, sting, and itch on both peptides. Since they're compatible in solution and the second one is anti-inflammatory, combining them works. Nine out of ten times now there's zero reaction.
