GHK-CU Dose?

Summary

What doses and schedules do people actually use for GHK-Cu?

Users report daily doses ranging from 0.5 mg up to 5 mg, with 2 mg and 3 mg being common starting points. Some titrate up gradually to reduce bruising or discomfort at injection sites, while others jump straight to higher amounts. A few combine it with KPV or run it alongside BPC-157 and TB-500. Opinions split on whether to cycle or stay on continuously.

What this discussion establishesWhere people disagree

Whether to cycle off or run continuously, and what constitutes an effective versus excessive daily dose.

Still open

How long to stay on a given dose before increasing, and whether gut issues or other side effects are related to GHK-Cu.

Nothing here is advice.

Didn't come across this when I searched... What's the usual dosing schedule for GHK-CU?

Two milligrams works well in my experience. Yet with peptides the suggested amounts can be all over the place.

I usually go with KLOW in amounts of three point seven five milligrams initially then point seven five milligrams repeated three times.

To be honest upfront my usage involves ghkcu blended together with kpv. Initially I combined them inside the needle but these days I blend the containers beforehand. Anyway I followed what amounted to a gradual increase in dosage mostly to avoid any discomfort. I started with point five units across several days then one milligram across roughly seven days then a pair of days at one point five and currently I have maintained two milligrams each daybreak across about thirty days. It worked out well that I eased into it since although there was never any sharp pain there was quite a lot of discoloration around the spots where I injected during the opening seven to fourteen days. I plan to keep using ghkcu along with kpv without breaks as long as no issue arises that would make me quit. I do this either during a particular cycle with other items or on their own.

Recently took two milligrams via injection. Experienced no irritation whatsoever. The vial contained one hundred milligrams and received three milliliters of bacteriostatic water. Its potency meant I only used six units.

Four milligrams each day seems to be providing me with favorable effects.

I opened a new hundred milligram container yesterday evening and mixed three milligrams using thirty units of bacteriostatic water. The sting was intense this time. Usually the discomfort stays pretty light but last night it stopped me from resting even though I can doze off during loud shows. The earlier batch caused far less discomfort. My regular combination includes three milligrams of GHK-Cu plus five hundred micrograms each of BPC-157 and TB500. Prednisone has left my skin thin from an autoimmune issue and after two months the mix looks like it is making a difference. The surface no longer splits open from light contact with furniture though it remains delicate and feels like it has improved to roughly where it was a year back. Outdoor physical tasks make weak skin especially frustrating so I am quite satisfied with how things stand.

Maybe I'll test that amount once I kick off the next cycle.

Started my two milligram daily dose several days back. Fifty milligrams blended with three milliliters of BA. The spots where I inject feel fine but earlier today my stomach felt like it was burning up. Unsure if there's a connection. We'll find out because I'm not stopping now! Hookem!

I'm curious if cycling is part of your routine. Taking three milligrams daily delivers effects I enjoy so much that pausing holds no appeal for me.

I administer five milligrams each day of the hundred milligram GHK-Cu after dissolving it in three milliliters of BAC water. Half-inch needles measuring twelve point seven millimeters go into my rear. Previously I ran into site reactions from shorter needles when injecting into my stomach or love handles, yet these longer ones placed in the buttocks produce none. I keep going straight through without breaks until the whole supply is gone.

I've been checking around for details on amounts to use with different peptides and related items like NAD+ pulled from published research papers. A few sites pull that material together and one includes a handy mixing tool. Separate discussions cover amounts and schedules for GHK-Cu. My partner began at one milligram each day with five days using followed by two without during her opening stretch. I'm curious how long before raising it to two milligrams daily what the full on and off stretches should run and if she picks up at the higher level after stopping. For appearance related uses of the compound there seem to be plenty of conflicting points on amounts schedules and reactions after looking into it over several weeks it feels even less clear. I've been using it myself for seven days at two milligrams daily and unlike reports from others it causes no sharp sensation at the injection spot does that mean things are fine. My profile has a search suggestion that could help.
