GHK-Cu from $34.99 Pinealon from $45.00 ## Price snapshot ### GHK-Cu Current low $34.99 current listings 7-day low — not enough history yet 30-day low — not enough history yet 30-day change — not enough history yet ### Pinealon Current low $45.00 current listings 7-day low — not enough history yet 30-day low — not enough history yet 30-day change — not enough history yet ## GHK-Cu GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a molecule Pickart and Thaler first pulled out of human plasma in 1973.

Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. | Preclinical | | Mechanism of Action | GHK-Cu works mostly as a copper shuttle and a signaling peptide. It binds Cu(II) with high affinity (log K around 16.4, close to albumin's 16.2) and can supply or regulate copper for copper-dependent enzymes like SOD1, lysyl oxidase, cytochrome c oxidase, and… | The proposed mechanism of Pinealon is rooted in the Khavinson school's broader theory of short-peptide tissue-specific bioregulation. The full theory is worth understanding because it underlies all twelve Russian bioregulator compounds in this catalog. The… | | Half-Life | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | Not formally characterized in humans. Short regulatory peptides of this class are cleared from plasma within minutes; the Khavinson framework proposes durable downstream gene-expression effects that outlast the brief dosing window, which is the stated rationale for pulsed cycling rather than continuous dosing. | | Typical Dose Range | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) | Subcutaneous (primary route): 2-10 mg/day, typically 3-5 mg, in pulsed 10-20 day cycles, 2-4 cycles/year. Intranasal: 150-800 mcg per nostril daily. Research use only; oral dosing is not recommended because the peptide is largely degraded by GI proteases. | | Dosing Frequency | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. | Once daily during a cycle (morning preferred); some advanced users split into AM + midday doses. Not dosed continuously year-round - cycles are pulsed. | | Administration | Subcutaneous, Topical | — | | Side Effects | Topical GHK-Cu is generally well tolerated; higher-concentration formulations (4-5%) raise the odds of irritation, redness, or stinging. Injectable use has no safety data from controlled trials; the main theoretical concern is copper accumulation with repeated… | The side-effect profile of Pinealon, based on the available Russian clinical literature and user-reported experience, is described as mild and uncommon. Whether this reflects genuinely low toxicity or inadequate reporting in the available studies is a… | | Molecular Weight | Free peptide (GHK): 340.38 Da (C14H24N6O4).

GHK-Cu is a skin, hair & aesthetics that ghk-cu works mostly as a copper shuttle and a signaling peptide. it binds cu(ii) with high affinity (log k around 16.4, close to albumin's 16.2) and can supply or regulate copper…. Pinealon is a nootropics that the proposed mechanism of pinealon is rooted in the khavinson school's broader theory of short-peptide tissue-specific bioregulation. the full theory is worth understanding because…. The two differ in mechanism, half-life (~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) vs Not formally characterized in humans. Short regulatory peptides of this class are cleared from plasma within minutes; the Khavinson framework proposes durable downstream gene-expression effects that outlast the brief dosing window, which is the stated rationale for pulsed cycling rather than continuous dosing.), and typical dose range. ### Which has the longer half-life, GHK-Cu or Pinealon? GHK-Cu has a half-life of ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study). Pinealon has a half-life of Not formally characterized in humans. Short regulatory peptides of this class are cleared from plasma within minutes; the Khavinson framework proposes durable downstream gene-expression effects that outlast the brief dosing window, which is the stated rationale for pulsed cycling rather than continuous dosing.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, GHK-Cu or Pinealon? Lowest listed price on BodyHackGuide: GHK-Cu from $34.99, Pinealon from $45.00. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack GHK-Cu and Pinealon? Stacking depends on mechanism overlap, safety profile, and goals. GHK-Cu and Pinealon should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
