GHK-CU / STUDY AMOUNTS
What GHK-Cu dosage did studies use?
Loren Pickart's work led to tests in cells, skin, hair, and animals. Each kind used a different amount. None gives you a proven amount for shots.
Why don't the study amounts fit one scale?
Loren Pickart's early work led to tests that can't be lined up neatly. In one dish, GHK-Cu raised collagen from 10 to minus 12 through 10 to minus 11, then peaked near 10 to minus 9 [1]. Collagen is the strong protein beneath your skin. A dish amount doesn't tell you what belongs in a cream or shot.
Skin products ranged from 0.05% to 2% by weight. A two-part hair lotion used 50 to 100 milligrams per milliliter [4]. A dish, cream, and scalp lotion move GHK-Cu into tissue in different ways. Their figures don't belong on one dose chart.
Rat tests used shots, nose drops, or feeding tubes. The amount also changed with the illness being studied. None of these figures is a human dose, and no sound plan exists for whole-body use in people. The studies can't set a safe amount for you or your doctor.
What do all the rat amounts really mean?
Animal tests tied to Pickart's work used a very wide range. Lung tests gave belly shots every other day at 0.2, 2, and 20 micrograms for each gram of body weight each day. A microgram is one millionth of a gram. Other lung work used 2.6, 26, and 260 micrograms per milliliter each day, while dust-damaged lungs were tested with 2 and 20 milligrams for each kilogram.
A bowel test gave 20 milligrams for each kilogram through a feeding tube each day. Aging and memory tests used nose drops at 15 milligrams for each kilogram, either daily or three times a week. Rat behavior tests ranged from 0.5 micrograms to 0.5 milligrams for each kilogram. Every one of these was an animal test.
The animal, the way GHK was given, and the illness all changed. Some papers used GHK alone, while others used GHK-Cu. A nose drop, belly shot, and feeding tube don't move a compound through a rat the same way.
No animal amount becomes a dose for a person. We don't know how your body would handle it. The long list mainly shows that shots still lack a tested human amount.
How did each test put GHK-Cu into tissue?
Human work linked to Pickart's compound usually put it on skin. Animal tests also used shots, nose drops, and feeding tubes. Wound tests used gels, dressings, fibers, and very small needles. Each method changes how much reaches living tissue.
GHK without copper crossed whole skin poorly [15]. Very small needles helped about 134 nanomoles pass through. A nanomole is a lab measure for an amount far too small to weigh at home. Almost none crossed skin that was left whole [15].
One test kept about 97 micrograms of copper per square centimeter of skin for 48 hours; a microgram is one millionth of a gram. The paper used a raised 2 to mark the square-centimeter area. It wrote the slow movement as 10 to minus 4 centimeters per hour [5], meaning very little copper moved through. Those figures didn't show whether that amount was safe or useful.
These results aren't directions for you. They tell what happened in one set of tests. A different product may deliver a different amount to your skin.
How long does GHK-Cu stay in the body?
Pickart's work never settled how long GHK-Cu stays in human blood, and copper-free GHK broke down quickly when mixed with rat blood. Later papers guessed that it might last about 1 to 2 hours. That isn't a proven time in people. The copper form may last longer.
GHK-Cu stayed whole best near pH 5, meaning mildly sour, with a 1:1 copper mix [15]. A sound mix looked blue-violet. Brown or green showed that the pair was breaking apart. Color alone can't tell you whether every jar is sound.
Some very sour products made with vitamin C may split off the copper. Other skin acids may also split the pair [15]. The copper bond stays tight in mild conditions [7], but no bond protects the pair in every product mix.
Does a larger amount work better?
Pickart's cell work doesn't show that more is better. The dish scale ran from 10 to minus 12 through 10 to minus 9, and raised collagen output in those skin cells [1]. Collagen is the strong protein under your skin. The cells didn't grow in number.
Another dish used from 1 to 500 billionths of a gram per milliliter. The cells released more of a protein used to grow blood vessels. Even the top amount didn't harm those cells [11]. A dish still can't set a safe amount for you.
Skin adds another hurdle. A jar can hold plenty of GHK-Cu while little reaches a living cell. The label can't tell how much your skin will take in. The product mix and the way it's used both matter.
Animal and dish amounts don't become human advice. Your doctor would need sound studies in people before judging a whole-body dose. Those studies don't yet exist.
