Look everyone, Nard said it so therefore it MUST be fact. His stance is 100% undeniable and is w/o question the ONLY correct answer. His anecdotal evidence involving a trial of exactly 1 is far more credible than your data collected in the exact same manner. /sarcasm
Look man, even if you are right (which you're not based on my personal experience along with several dozen people who I personally know first-hand in RL and only 1 had no response) you're a douche.
I tried to give you the benefit of the doubt from your previous needlessly aggressive posts but I can tell that's just how you roll... everything is an ePeen contest.
I'm new here and I can already tell that my experience here will be made instantly better by adding you to my ignore list.
Bro,
I stopped reading after you rambled about zinc LMFAO.
But let me give you the benifit of the doubt and not speak anecdotally and lets cover theoretical mechanism regarding this molecule/chemical.
GHK-Cu for decades say that it was probably about 90/10 with the 10% being those who don't have ISR.
Based on what trial ? what outcome metric ? what dose ? what end point ? Published where ?
There is no human clinical data linking GHK-CU injection to ISR correction nor is there even a fucking standarizerd clinical biomarker for "having ISR" had to LOL at that part.
When injecting GHK-Cu sub-q it's imperative that you have proper zinc levels in your system as well. Preferably before starting GHK-Cu injections. Do you take a ZMA supplement?
Lets use some math here since I dont even think you understand how a chemical copper attachment converts to mg in a human.
Source: PubChem (CID: 161323)
GHK-CU is a 1:1 complex:
1 molecule GHK = 340g/mol
1 copper ion (Cu+2) = 63.5g/mol
For a total 403g/mol
So copper makes up 15.7% of the weight here

Now lets say your doing a daily injection of
2mg for example
2mg + 0.157 =2.157 mg 0.314mg of copper
Basically
314 micrograms of copper

Based on the Tolerable Upper intake Level the (UGL)
is 10mg a day in adults, (Which is no where near what GHK contains LMFAO) which is far below UL
Let me even be generous and nice here and say your taking 5mg of GHK-Cu, that still fucking below the UL limit.
So claims like:
add proper zinc into your system to oppose the additional copper first.
Are fucking comical to me n shows me you have 0 understanding of chemistry, unit conversion and pharmacology.
On top of the Zinc deficiency is rare in healthy adults in developed countries especially if your not vegan.
Even after giving you the benefit of the doubt, this doesn't even take into account the Bac water and PH balance when mixed with the peptide.
But to dumb it down for you since you need it:
When mixed with Bac water, due to the PH balance with copper, the complex partially falls apart which means (free coper ions locally)
which = sting/ PIP irratation meaning its not doing fuck for skin LMFAO
But again let me give you the even more of the benifit of doubt and assume the copper is intact, copper is required for Lysl oxidase -> collagen cross linking, but here is the part most people miss, that enzyme is already functionally normal in healthy adults unless your copper deificnet, so adding more copper doesnt linearly increase Lyme activity since there already saturated due to the body's homeostatic buffering.
TDLR;
In copper sufficient healthy adults(Majority of adults), collagen production is not limited by copper availability, so systemic GHK-Cu is unlikely to produce meaningful aesthetic improvements beyond wound healing. Its placebo if anyone reports skin glowing claims n scams you
I just single Handedly Eviscerated your post using science and not annecdotes. Have a good day
