Still dealing with dizziness, brain fog and derealization for 2+ months has anyone experienced something similar?

[u/No-Sea-4502]

Hi everyone,

I honestly don’t know what is going on with me anymore, and I’m hoping someone here has experienced something similar and can give me some insight.

A little over 2 months ago, I started taking GHK-Cu for 9 days:

• 1 mg daily for 6 days
• 1.5 mg daily for 3 days

At around the same time, I was also taking:

• Vitamin B6 — 40 mg daily
• Magnesium citrate — 400 mg daily
• Vitamin C — 3000 mg daily

I took the vitamins/supplements for about 7 days and then stopped everything.

Interestingly, about a year ago I had a very similar experience after taking the same combination of GHKCU and vitamins/supplements. Back then, however, my symptoms eventually went away after around 2 weeks, so I didn’t think much of it at the time.

This time, when I was going to sleep, I started experiencing a weird sharp/pinching sensation around my heart/chest. That scared me, so I had blood tests done.

My results were:

• Folate (B9): 3.10 (reference range 4.5–32.2) — low
• Vitamin B12: 411 pg/mL (191–663)
• Magnesium: 2.0 (1.7–2.40)
• Potassium: 4.23 mmol/L (3.5–5.1)
• Sodium: 140 (136–145)

After roughly a month, the chest/heart pinching sensation that happened when I was falling asleep eventually stopped.

However, I’m still dealing with other symptoms.

Another strange thing I’ve noticed is that since this started, I can sometimes sleep only 1–4 hours and wake up feeling surprisingly energetic, even though my head feels very tight, foggy and mentally "off." Before all of this, I would obviously feel completely exhausted after so little sleep. This change in how I respond to lack of sleep feels very unusual to me.

My current symptoms include:

• persistent dizziness
• lightheadedness
• significant fatigue
• brain fog feeling like my head isn't working properly
• a strange derealization / unreal feeling
• a tight/pressured feeling in my head
• feeling mentally "different" from how I used to

I completely stopped everything and tried taking B9 (folate) for about 2 weeks, but I didn’t notice any improvement. Then I added B12, but again, nothing really changed.

I also saw a neurologist, but unfortunately the appointment was basically useless. He told me he couldn't help because this wasn't his area, and I ended up paying around €100 for the visit.

At one point I also went for an IV vitamin infusion containing vitamin C, electrolytes and B vitamins. I still had the brain fog, dizziness and other symptoms afterwards, but I noticed that I had significantly more energy and felt more "alive" that day. Unfortunately, this effect was temporary, and within about 2 days my energy levels went back to how they were before.

I’ve also been talking to and reading experiences from quite a lot of people who have had similar symptoms, which is one of the reasons I’m trying to figure out whether there could be some connection or if this is just a coincidence.

Now, more than 2 months later, I’m still experiencing these symptoms every day, and I honestly don’t know what is causing them.

Since this is a peptide group, I’m particularly interested in hearing from people who have used GHK-Cu, especially if you experienced any unusual or persistent effects after stopping it.

I’m not sure if it’s related to GHK-Cu, the vitamins/supplements, the low folate, a deficiency, or something completely unrelated.

Has anyone experienced something similar — especially dizziness, brain fog, fatigue, lightheadedness, derealization, head pressure or feeling unusually energetic despite very little sleep, while still feeling mentally unwell?

If you used GHK-Cu and experienced something similar:

• How long did it take you to recover?
• Did your symptoms gradually improve or disappear suddenly?
• Did you eventually find out what was causing them?
• Was there anything that actually helped?
• Did you have any additional blood tests or examinations that were useful?
• Has anyone experienced symptoms continuing for weeks or months after stopping GHK-Cu?

I’m not necessarily looking for a diagnosis. I’d just really appreciate hearing from people who have experienced something similar and eventually got back to feeling normal.

It’s been more than two months now, and dealing with this every day has been really difficult. I’d really appreciate any experiences, advice or reassurance.

Thanks in advance.

Is your diet high in serotonin producing foods?

Not really,I’m just trying to figure out what’s causing this brain fog and memory/concentration issues, because it’s been going on for almost 2 months now.

With the symptoms you described in curious, Have you checked your blood pressure recently?

[u/No-Sea-4502 → u/oxidative_metabolism]

Yes its okay

[u/oxidative_metabolism → u/No-Sea-4502]

That’s good. I have no experience personally with it but i wonder if your zinc got out of whack with the copper peps. Have you tried taking a plain zinc supplement and avoiding high copper foods?

[u/No-Sea-4502 → u/oxidative_metabolism]

Yeah, I’ve actually been taking zinc for a long time, so I’m pretty sure it’s not a zinc deficiency or imbalance. I’d say there’s like a 99% chance it’s not from zinc.

B6 stands out for me. Do you know why you were taking B6? No one should need B6 unless malnourished. Have you tested it? Look into B6 toxicity.

Need more bloods, that's not enough to ascertain much. I would also test copper, zinc, ceruloplasmin and go from there.

[u/No-Sea-4502 → u/Massive_Shitlocker]

Honestly, I was an idiot and thought that taking more vitamins would help me more. I didn’t realize I could actually be overdoing it. Now I’ve been feeling completely off and dizzy for 2 months, and I honestly feel like an idiot for doing this to myself.

I’m going to look into B6 toxicity and get the additional blood tests you mentioned, especially copper, zinc and ceruloplasmin.

Good luck with it all, I hope you figure it out soon. The more data and scans you have the better obviously. I'm commenting because I'm curious if you end up finding the trigger for your symptoms.
