Turn back the clock at the cellular level. GHK-Cu is the copper peptide your body already makes, just less of it every year after age 30. By your 60s, levels drop by more than 60%, and so does the signal that tells your skin to renew, your hair follicles to thicken, and your tissue to repair. At Better Med Spa in Lincoln Park, Dr. Brett Brechner, DO, offers medically supervised GHK-Cu therapy as a subcutaneous injection or an oral capsule. Choose the format that fits your routine. Start with one month at $300, or commit to a full three-month protocol at $810 and save.
GHK-Cu targets the visible and internal signs of cellular aging: thinning, crepey skin; loss of elasticity and firmness; slower wound and tissue repair; hair thinning and follicle shrinkage; and sluggish recovery from inflammation. It may also support post-procedure healing after laser resurfacing, microneedling, or surgery. It is a whole-body rejuvenation tool for adults 30+ noticing their body bouncing back more slowly than it used to.
GHK-Cu is a copper-binding tripeptide your body produces naturally. It signals fibroblasts to build collagen and elastin, activates angiogenesis (new capillary growth), reduces inflammatory cytokines like TNF-alpha, and helps stem cells migrate to repair sites. In the scalp, it supports follicle size and the growth phase of the hair cycle. It works with, not against, your body's own regenerative pathways.
Better Med Spa is a physician-led practice in Lincoln Park under the direction of Dr. Brett Brechner, DO. Every peptide patient starts with a medical consultation, a tailored protocol, and ongoing oversight, not a cash-and-carry vial. We source from licensed 503A compounding pharmacies, offer both injectable and oral formats, and credit your consultation fee toward treatment.

If you've spent any time researching regenerative medicine, anti-aging peptides, or the quiet boom in "longevity skincare," one three-letter code keeps surfacing: GHK-Cu. It is perhaps the most studied peptide in dermatology, and for good reason — it is one of the few molecules your body naturally produces and one whose decline tracks the visible signs of aging almost perfectly.
At Better Med Spa & Wellness in Lincoln Park, Chicago, we now offer medically supervised GHK-Cu copper peptide therapy under the direction of Dr. Brett Brechner, DO. Patients can choose the format that works for their lifestyle — a subcutaneous injection or a once-daily oral capsule — at $300 for a one-month supply or $810 for a discounted three-month cycle. Every protocol begins with a medical consultation, and your consultation fee is credited toward your first month of treatment.
This guide is a deep dive into what GHK-Cu is, what the science actually supports, who it's for, how we prescribe it in our Lincoln Park clinic, and how to decide whether it's the right next step for your skin, your hair, or your broader longevity plan.
GHK-Cu is shorthand for the glycyl-L-histidyl-L-lysine copper complex — a small peptide made of three amino acids bound to a single copper ion. It was first isolated in 1973 by Dr. Loren Pickart from human plasma, and since then it has been the subject of more than 200 published studies spanning wound healing, dermatology, hair biology, gene expression, and most recently, longevity research.
A few things make GHK-Cu unusual among peptide therapies:
In plain language: GHK-Cu is one of your body's natural "repair signals," and replenishing it may help restore the regenerative signaling that quietly weakens over time.
GHK-Cu does not force your body to do something artificial. Instead, it interacts with pathways that are already part of normal biology. In lab and animal studies, researchers have documented several of its mechanisms:
1. Collagen and elastin production. GHK-Cu signals fibroblasts — the skin's collagen-producing cells — to upregulate the production of types I, II, and III collagen, as well as elastin, glycosaminoglycans, and decorin. This is the same ECM (extracellular matrix) scaffolding that gives young skin its firmness and bounce.
2. Angiogenesis. GHK-Cu stimulates the formation of new capillaries, which improves tissue perfusion. Better blood flow means more oxygen and nutrients reaching skin, scalp, and connective tissue.
3. Anti-inflammatory signaling. It reduces levels of pro-inflammatory cytokines — including TNF-alpha — and dampens oxidative stress, the two drivers most linked to the visible signs of skin aging.
4. Stem cell mobilization. In wound-healing models, GHK-Cu supports the migration of progenitor cells to areas needing repair.
5. Gene expression. A 2010 study using the Broad Institute's Connectivity Map database found that GHK-Cu at physiologic doses modulated approximately 31% of the 16,000+ human genes evaluated — shifting gene expression toward a more youthful pattern. This is part of why longevity researchers have taken interest in it.
6. Hair follicle signaling. GHK-Cu supports the anagen (growth) phase of the hair cycle, appears to protect dermal papilla cells from DHT-induced shrinkage, and has been shown in lab studies to increase follicle size and density.
None of this is marketing language — these are mechanistic findings from peer-reviewed literature. What GHK-Cu does not do is override the aging process. It supports and amplifies the body's existing regenerative signaling.
Important clinical note: GHK-Cu is not FDA-approved to treat, cure, or prevent any specific disease. At Better Med Spa, it is prescribed off-label by a licensed physician after medical evaluation, and dispensed through licensed 503A/503B compounding pharmacies. Patient candidacy is determined case-by-case.
Most Chicago patients who ask us about GHK-Cu fall into one of four bucket categories:
GHK-Cu is frequently paired in our Lincoln Park clinic with collagen-stimulating treatments such as microneedling, BBL (BroadBand Light), and MOXI from the mJoule platform. The peptide supports what the laser or microneedle physically triggers — a more efficient wound-healing and collagen cascade.
GHK-Cu is not a one-size-fits-all therapy, and candidacy is confirmed through a medical consultation with Dr. Brechner or one of our nurse practitioners. In general, we consider the following:
Good candidates:
Not candidates (or requires additional screening):
One of the most common questions we get at our Chicago clinic: do I choose the shot or the pill? Here's how we walk patients through it.
Both formats are priced identically at Better Med Spa — $300 for a one-month supply or $810 for a three-month cycle. You can even begin with oral and transition to injectable (or vice versa) between cycles based on how your body responds. We don't steer you toward the more expensive option — because the price is the same.
A typical GHK-Cu protocol at Better Med Spa runs as follows:
Week 1: Medical consultation with Dr. Brechner (or a nurse practitioner), intake labs if indicated, and prescription sent to our partner compounding pharmacy.
Weeks 2–4 (Month 1): Initial cycle. Injectable patients are taught subcutaneous self-injection technique in-office. Oral patients start daily capsules. Most patients report early changes — improved skin feel, reduced inflammation, or fewer shedding hairs — by the end of week 3 or 4.
Months 2–3: Cellular signaling continues to accumulate. Collagen remodeling takes time — a fibroblast doesn't build new collagen overnight — so this is the window where visible skin firmness, texture, and hair density improvements become most noticeable.
Months 4+: Many patients take a 4–8 week break, then run a second cycle. Others stay on a maintenance dose. Longevity-focused patients may continue indefinitely under ongoing medical supervision.
One of the reasons patients choose Better Med Spa for peptide therapy over online telehealth scripts is that we can actually build a coordinated protocol. A few of the most common pairings:
GHK-Cu + Microneedling. The microneedle creates controlled micro-injuries that trigger a natural wound-healing cascade. GHK-Cu amplifies the collagen-and-elastin side of that cascade. Patients often schedule peptide therapy to overlap with a 3- or 6-visit microneedling series.
GHK-Cu + BBL / MOXI Laser. Our mJoule platform — installed as part of our 2025 capital investment — handles everything from sun damage (BBL) to texture and tone refinement (MOXI). GHK-Cu supports the dermal remodeling phase that happens for weeks after each session.
GHK-Cu + BPC-157 / TB-500 ("Wolverine Stack"). Patients rehabbing a tendon, ligament, or chronic joint issue often run BPC-157 and TB-500 for localized and systemic tissue repair. Adding GHK-Cu gives the skin, scalp, and connective tissue a rejuvenation layer at the same time.
GHK-Cu + GLP-1 Weight Loss. A surprising number of our semaglutide and tirzepatide patients ask about GHK-Cu as they approach their goal weight — because rapid weight loss can leave skin feeling looser. GHK-Cu supports the dermal remodeling needed to "catch up" to the new body composition.
GHK-Cu + PRP Hair Restoration. For patients pursuing a hair-density protocol, GHK-Cu is a natural addition to platelet-rich plasma injections or in-office topical treatments.
Peptides have exploded online. You can find GHK-Cu sold in gray-market "research" formats with no physician oversight, no sourcing transparency, and no plan. That is not what we do.
1. Physician-led care. Dr. Brett Brechner, DO, is our medical director. Every peptide patient receives a direct medical evaluation and an individualized protocol — not a checkbox intake form.
2. Licensed compounding partners. Our GHK-Cu is sourced through state-licensed 503A and 503B compounding pharmacies with full chain-of-custody documentation.
3. Both formats, one price. We offer injectable and oral GHK-Cu at identical pricing so you can choose the format that fits your life, not the one your clinic profits more from.
4. Lincoln Park convenience. We're at 2117 N Halsted Street — two blocks from the Armitage Brown Line stop, easy parking in the neighborhood, and a short drive from Lakeview, Old Town, Bucktown, Wicker Park, and the Gold Coast.
5. Integrated practice. We're a full-service med spa. If GHK-Cu fits alongside Botox, filler, microneedling, BBL/MOXI laser, weight loss, hair restoration, or hormone optimization, we can coordinate all of it under one roof.
6. Transparent pricing. $300 per month or $810 per three-month cycle. No membership required. No hidden fees. Consultation credited toward your first month.
7. 129 Google reviews at 4.8 stars. Our patients talk, and they rate us honestly.
Better Med Spa & Wellness is located in the heart of Lincoln Park, one of Chicago's most established medical and wellness corridors. We are easily reached by patients across:
We are open seven days a week — Monday through Thursday from 10 AM to 7 PM, and Friday through Sunday from 9 AM to 5 PM — with extended evening and weekend availability to accommodate professionals, parents, and commuters.
No peptide in the GHK-Cu class is FDA-approved as a pharmaceutical product for anti-aging. It is prescribed off-label by licensed physicians and dispensed through state-licensed compounding pharmacies. We follow all applicable regulations around compounded peptide prescribing.
In many cases, yes — but stacking should be done under medical supervision. During your consultation, Dr. Brechner will review your goals, current supplements and medications, and any prior peptide experience to build a coordinated plan.
Reported side effects are generally mild. With the injectable, patients may see minor redness, tenderness, or bruising at the injection site. With the oral capsule, mild GI discomfort is the most common report. Systemic side effects are uncommon but may include brief headache or lightheadedness. All peptide therapies carry some risk; your provider will review candidacy and contraindications.
Book a consultation through our website or call (312) 285-2618. During your visit, we'll review your health history, discuss your goals (skin, hair, recovery, longevity, or a combination), recommend the right format and cycle length, and place your prescription. Most patients begin treatment within a week of their consultation.
Your body already knows how to repair itself. GHK-Cu is the signal that tells it to do so — and at Better Med Spa in Lincoln Park, you can get it under real medical supervision, at a transparent price, in the format you prefer.
One month, $300. Three months, $810. Injectable or oral. Your choice.
