GHK-Cu is a lyophilized copper-binding tripeptide complex studied in-vitro for extracellular-matrix and fibroblast research
On the other hand, studies exploring a possible association between cancer and extremely elevated vitamin B12 levels may understandably raise concerns
Peptides are available through research supply channels

Ongoing low-dose maintenance (experimental) Continuous dosing approach: Dose: 1-2mg daily OR 3-5mg 2-3x weekly Duration: Ongoing (not cycled) Goal: Maintain constant telomerase activation Status: Experimental, not from research protocols Rationale: Telomerase needs continuous activation to maintain telomere length Cyclic dosing may allow regression between cycles Low-dose continuous might provide stable benefits Similar to maintenance protocols for other peptides Continuous dosing options: Advantages of continuous: No "off" periods where benefits regress Potentially stronger cumulative anti-aging More like natural physiologic regulation Easier to stack with other peptides Disadvantages: Much higher annual cost ($1,800-3,600 vs $300-600) No long-term safety data Uncertain if better than cyclic approach Storage challenges (more reconstitution) Deviates from proven protocols Current recommendation: Stick with proven 10-day cycles for most users Consider continuous only if cyclic approach inadequate Start with standard protocol first Assess your individual response Consult with peptide-knowledgeable physician Use our peptide cycle planning guide to design your Epithalon protocol

AOD 9604 will only specifically act on fat metabolism, thereby possibly allowing safer and more specific long-term administration and situation unlike in various other weight loss medications, since a variety of other foci are involved
So if someone is low in B12 and they consume alcohol, they not only don't have enough B12 to help 'clear away' the alcohol toxins but they also risk increasing homocysteine levels which I believe is that feeling of heat/hangover that can persist when there isn't enough B12 to reset the body
