Husband and I have been on the shots (GHK-cu & KPV) for over 2 weeks. Have missed a couple nights. Last night’s shot caused a reaction for my husband. Same vials for us both.

He has a raised rash and it feels hard underneath. It was itchy and he ended up putting itch cream on it and taking Benadryl today as a ‘just in case’. Is this a sign he is building up for an allergic reaction? He skipped tonight.

His allergies have been acting up lately and he’s been more itchy.

Full disclosure: I didn’t filter the first vials but I have filtered the newest one.
 
I've had this happen a few times. It seems random and goes away on its own. Maybe it's a certain injection point that is sensitive or something. Still, your husband may be different from me, so it wouldn't hurt to keep an eye on it and him for further signs of an allergic reaction or infection.
 
IDK but wife and I are using Klow, and I didn't get the lump under skin and mild irritation until 5 or 6 shots in. I know this may not help much but maybe someone more knowledgeable than me on the subject will chime in, as I chose to just deal with it and continue and irritation goes away in about 24hrs for me
 
From Gemini about GHK-Cu: "Noted for intense sting. Primarily localized irritation, but copper sensitivity can cause systemic hives."

If you want to freak out (motivation to discontinue or to get EpiPen or Neffy):

Epi Pen resources?

Has anyone managed to buy some Epi Pens as a hedge against potential anaphylaxis? If so, what was your process? Is there a go-to telehealth that can issue a scrip?

We have some. Husband is deathly allergic to yellow jackets and son is allergic to shellfish and penicillin.
 
Some people decide to switch to GHK (without the Cu/copper) and seem fine with that:

all the reports about ghk basic I’ve seen have reported complete comfort

Personally, I have only used GHK-Cu topically so far, because of such reports with the injectable version (despite the injectable version having more benefits). PWGrove's website has good pricing on the topical version as does Uther's US warehouse (UtherPep).
 
A 2014 paper mentions a 1:1 mix of copper and copper-free GHK, saying that just copper-free is also fine:

quoted said:
GHK and DNA: Resetting the Human Genome to Health

GHK has a very high affinity for Cu(2+) (pK of association = 16.4) and can easily obtain copper from the blood’s albumin bound Cu(2+) (pK of association = 16.2). Most of our key experiments used a 1:1 mixture of copper-free GHK and GHK:Cu(2+). In wound healing experiments, the addition of copper strongly enhanced healing. However, others often obtain effective results without added copper .

Google Gemini said:
By using a mixture that has more GHK than copper, you provide a "buffer". Any copper that might have caused a "sensitivity" reaction is instead snapped up by the extra GHK and turned into a protective, antioxidant complex. This is likely why the paper notes that GHK is safe and effective even without adding extra copper—it just uses what your body already has available .

If you use copper-free GHK, it will "strip" copper from albumin in your blood because its binding strength (pK=16.4) is higher than albumin's (pK=16.2). The authors used a 1:1 mixture of copper-free GHK and GHK-Cu to ensure a balance between immediate activity and the ability to interact with the body's natural regulatory molecules.

Using an excess of GHK ensures that there is zero chance of "free" copper floating around. Any extra copper in the environment is immediately "snapped up" by the empty GHK. f"Free" or "loose" copper is dangerous because it is chemically unstable and acts as a pro-oxidant. When copper ions are not safely "caged" (sequestered) within a peptide like GHK, they trigger a chain reaction of cellular damage.

At least two people here (like @kmamz296 and @RadicalCrimson) have done a mix (50 copper : 9 basic and 1:1):

I used to get awful ISR with 50/10/10 GLOW. It would take a few hours but would last the rest of the day… just persistent burning at the injection site. I know it sounds crazy… but someone on an old QSC telegram group suggested I add some GHK-Basic (so without the -Cu) to the combo and I’ve been adding ~9mg of GHK-basic and the ISR/burn is COMPLETELY GONE. Not sure if the GHK-basic is scavenging some free copper that causes the ISR or what. But adding a little GHK-basic has made GLOW easily tolerable for me

RadicalCrimson said:
Same, I was doing fine at 5mg/day of GHK-Cu with 3 close injections (1/2" needle), but one night I randomly got the bad ISR back that required ice packs all night.

Now I've added GHK-Basic (5mg/day, same as GHK-Cu) to the blend, zero ISR at the full dose in a single injection.

I would probably just go copper-free rather than doing a mix (which seems like more work, even if just adding to the same syringe or injecting separately). For the curious, a copper blood test is $11.34 at Fitomics and $27 at GoodLabs. Zinc is cheaper to test for.

Why copper-free avoids immune/allergy reactions:

Google Gemini said:
Feature GHK-Cu (Copper Complex) GHK (Copper-Free) Primary Immune Action Immunomodulatory. Attracts immune cells (macrophages, mast cells) to injury sites to kickstart healing. Anti-inflammatory. Primarily reduces pro-inflammatory cytokines and resets gene expression. Allergy Risk Level Higher. Adds the potential for metal sensitivity (copper) and higher histamine activity. Lower. Fewer "moving parts" for the immune system to react to; no metal ions. Histamine Interaction Known to stimulate mast cell migration. While this helps tissue repair, it can trigger localized itching/hives. Less likely to trigger acute mast cell responses; focuses on calming systemic inflammation. Metal Sensitivity Possible Contact Dermatitis or systemic reaction if you have a copper or nickel sensitivity. None. Ideal for those with known metal allergies. Injection Site Reaction Common. Known for "stinging" or "burning" and localized redness due to the copper ions. Rare. Usually very "smooth" and painless when reconstituted correctly.
 
I had a similar reaction to mots c once. I often got small itchy lumps from it but once I got a huge 15cm round deep firm lump under the skin in the subcutaneous fat tissue that was super itchy and took a week to get better, then never got it again. More severe local reactions or any signs of a general allergic reaction are a good reason to consider stopping it.

With his allergies already acting up he is much more likely to have that kind of response, in my experience. I deal with environmental and food allergies. So I noticed when my allergies are already bad I can't eat certain foods because it will trigger an allergic reaction when it normally wouldn't. Glad you are filtering now!
 
I take GHKcu (my little Blue Witch) regularly and sometimes, depending on the injection site on any given day I can develop a lump under the skin...I do dilute it w/extra bac water in the syringe and that does seem to help with that little lump.

I love the stuff, so no plans on stopping it...but playing around with injection sites seems to help as well.
 
I had been using ghkCu/basic 50:20 along with kpv injected first at the same site and some topical hydrocortisone for good measure… working my way up to 4.5mg/day divided doses… which was really working for stopping migraines… and there was no immediate sting at all but I would get stinging 2-5 hours later in the same leg at other pervious injection sites where I had bruises. I took this to mean that some sort of healing was going on.

About a week in, I was starting to get delayed itching and a persisting bump deep down that was itchy (not hives) at the injection site. I switched to using abdominal sq sites and the bumps all got much less. Then a few days after, my qd lira and ss31 injection sites (other leg) also developed delayed itchy bumps. And my scalp had been increasingly itchy as well as my overall skin. I have been a fairly environmentally allergic person in the past and due to the recent rains we are having an early spring allergy season here so that eas adding in.

This is still just one organ system (skin) so not anaphylaxis. It still seemed like a mast cell reaction, a mechanical irritation, but was extending to make me more sensitive to actual allergies too, as can happen. I started wondering if it was my actually pretty crappy quality needles and pen needles, maybe the rubber stoppers, or something in all the products (my rather $$$$ Rx’d generic lira pen actually came from CN so I am very suspicious it is also recon’d lyo’d pep).

I had talked to someone with a history of similar reactions who had taken 5 days of high dose brand name Zyrtec antihistamine (4 pills a day, but do check with your doctor to make sure you’re not missing or covering up increased anaphylaxis risk, which can be the case with those with atopic dermatitis or mast cell disorders, and mast cell disorders are apparently underdiagnosed since 50% of people with history of wasp sting anaphylaxis im one study turned out to have a mast cell clonal disorder ).

Continuing, with my neffies to hand, I am on day 3 of antihistamines and only 1.5mg of ghk and can say that it has given me relief from my insomnia 🤣 and I’m less itchy but still getting new itchy welts. I restarted topical hydrocortisone which helps.

I think I might try ghk basic alone next, on the copper theory, but I am a little worried that I might need to take a break from all injections to let my mast cells settle down if literally everything is triggering this.

Is anyone having this ghk reaction while also on tirz? Tirz is likely very good at suppressing mast cell inflammation. Would you please let us know if you take tirz and ghkcu and whether you have any kind of isrs?

Anyone getting a spreading reaction should be very cautious and quite likely more cautious than I am being. Antihistamines DO NOT treat or prevent anaphylaxis. Anyone with previous anaphylaxis is likely at higher risk for another episode. Epi does not save everyone who gets anaphylaxis!

I take Tirz and I’m on my 2nd round of ghkcu. I have no isrs, not even the post sting people talk about. But as everyone knows, we are all different on how we respond to things.

When I was on tirz, my longstanding residual frozen shoulder cleared up like magic a few days in microdosing. What dose of tirz are you on? Thanks for sharing even though we’re all different… there are some general trends!

I started maintenance recently so I went from 5 and 2.5 divided up in a week to 2.5 weekly now. Im still trying to figure that part out though

Thanks, that’s pretty efficient that you’re not needing too high a dose to get good effects. Keep us updated on how the ghkCu goes, too!

Why copper-free avoids immune/allergy reactions:
Excellent info 👍 👍 👍

And adding GHK to a GHK-Cu removes the sting feeling because the free GHK "captures" the excess free copper that normally is one of the reasons for some reactions and sting. Also, KPV may have the same properties as free GHK of capturing free copper

Still looking. I searched the web app for STG test results and only GHK-Cu came up.

GBBB is doing a traditional (slow ass) GB for every GHK (with a previous, undisclosed vendor):

quoted said:
GHK Basic 50mg - $55

GHK-Cu 50mg - $55

GHK Basic 100mg - $85

GHK-Cu 100mg - $85

GHK-Cu Cosmetic - $7/gram

That could be a no for me, except for the topical since shipping is included. The last day for the GB is the 20th.
 
PGB had GHK basic listed last week in their listing at STG. Was $50 for 45 mg plus $30 shipping ($80 total, but free shipping for orders over $300).

So GBBB's pricing is looking very good with free shipping (but still a traditional GB).
 
For GHK basic, YD Peptide sells 50-mg kit for $50, but about the same amount for shipping since no US warehouse.

And people are avoiding ISRs completely using hip (side of butt) for subq (instead of abdomen) for spicy peptides, including GHK-Cu (and KLOW) as well as MOTS-c. Tried it this morning for glutathione and seems to do the trick.
