What Patients Need to Know About Peptide Therapies | BPC-157, TB-500, GHK-Cu, NAD+, and GLP-1
Sandel Duggal offers medically directed Peptide treatments for patients interested in losing weight who want to ensure that the medications are being prescribed by highly qualified nurses who can closely monitor and customize treatments to each patient’s needs.
Peptides are short chains of amino acids — the same building blocks that make up proteins in the body. Many peptides that occur naturally act as signaling molecules, helping cells communicate with one another. Depending on the specific peptide, this signaling can influence appetite, inflammation, collagen activity, tissue repair, skin quality, and metabolic regulation.
“Peptide therapy” is not one single treatment, and it’s a mistake to treat all peptides as equally proven — or equally experimental. Some peptide-based medications, such as insulin, semaglutide, and tirzepatide, are FDA-approved and have been studied in large clinical trials.
What Treatments Are Offered?
At Sandel Duggal, the peptide-related treatments we offer include a BPC-157 + TB-500 recovery program, GHK-Cu topical skin renewal, and GLP-1/GIP-based weight-management injections (semaglutide and tirzepatide). We also offer an NAD+ + B12 program, which is often grouped with peptide wellness treatments.

How Do These Treatments Work?
Abdominoplasty is one of the most popular and transformative plastic surgery procedures. You might consider a tummy tuck for the following reasons.
This is a physician-directed, subcutaneous program used as a supportive recovery option — not a guaranteed healing treatment. BPC-157 is a peptide originally isolated from human gastric juice and is widely studied in animal models for tissue-repair signaling, inflammation modulation, and tendon, ligament, and muscle recovery. TB-500 is related to thymosin beta-4 biology and is commonly discussed for cell migration, tissue remodeling, and broader soft-tissue recovery.
The rationale is biologically plausible, but it’s important to be candid about the evidence base: a 2025 clinical review noted that the large majority of published BPC-157 research comes from animal studies produced by one research group, and that independent, controlled human trials are still scarce. A recent peer-reviewed primer for orthopedic and sports medicine physicians similarly concluded that BPC-157’s benefits for tendon and muscle repair are “largely unvalidated in human trials,” based on a single small human case series without a control group. A 2025 pilot study did find that a short course of intravenous BPC-157 was well tolerated in two healthy adults, which is reassuring but far from proof of effectiveness. We present this program as a supportive adjunct to a broader recovery plan (rest, physical therapy, nutrition), not as a stand-alone cure.
NAD+ is involved in cellular energy metabolism, mitochondrial function, and DNA repair signaling. B12 supports normal neurologic function and red blood cell production, and can be especially helpful for patients who are deficient. Our program is positioned as a supportive wellness treatment for energy and recovery, with individualized dosing — not as a proven anti-aging or disease-modifying therapy. Persistent or worsening fatigue should always be evaluated by a physician rather than assumed to be an NAD+/B12 issue.
GHK-Cu is a copper-binding tripeptide studied for its role in collagen support, skin remodeling, and post-procedure skin recovery. We offer GHK-Cu as a topical treatment or procedure-adjunct — not as a systemic injection. The FDA has specifically identified compounded injectable GHK-Cu as a substance of concern because of limited human safety data and the potential for immune reactions, and injectable GHK-Cu remains outside the FDA’s approved compounding pathway.[9] Topical use has a more established safety track record, which is why it’s our recommended route.
Patients can choose our GHK-Cu topical cream with or without added low-dose estradiol, compounded per individual prescription. GHK-Cu is included primarily for its collagen-support and skin-remodeling properties, while the estradiol is included because topical estrogen has its own separate, more established research base in dermatology — small clinical studies and a 2025 systematic review in the Journal of the American Academy of Dermatology have evaluated topical estrogen formulations for improving skin thickness, hydration, and elasticity, particularly in postmenopausal patients, though the review’s authors noted that evidence is still limited by small sample sizes, short trial durations, and the fact many studies used compounded, non-FDA-approved formulations. Combining the two ingredients in one cream is a compounding choice, not an FDA-approved combination product, and we’re transparent about that distinction with every patient.
Adding estradiol is not appropriate for every patient. Because even small amounts of topical estradiol are absorbed into the bloodstream, patients using the estradiol version need the same screening we’d use for any estrogen-containing product — see the estradiol-specific safety considerations later in this document. Patients who prefer to avoid systemic hormone exposure altogether can select the GHK-Cu-only formulation, which does not carry these same considerations.
Our GHK-Cu skin renewal cream is available in two formulations, compounded to your provider’s prescription:
- GHK-Cu topical cream — GHK-Cu alone, for patients focused on general skin-quality support, collagen signaling, and post-procedure recovery.
- GHK-Cu + estradiol topical cream — GHK-Cu combined with a low-dose topical estradiol, for select patients (typically peri- or post-menopausal women) seeking additional support for skin thickness, elasticity, and hydration alongside GHK-Cu’s collagen-signaling effects.
Adding estradiol changes the risk profile, so the combination formula is reserved for patients who complete additional screening. Topical estrogen can be absorbed systemically depending on the dose, application site, and skin barrier condition, and unopposed estrogen exposure carries a known risk of endometrial hyperplasia in patients who still have a uterus. For that reason, the GHK-Cu + estradiol cream is not appropriate for patients who are pregnant or breastfeeding, have a personal history of estrogen-sensitive cancer (including certain breast cancers), have an unexplained history of vaginal bleeding, or have a personal or strong family history of blood clots, stroke, or heart attack. Your provider will review your hormonal and cancer history, and may recommend periodic monitoring, before prescribing the estradiol-containing version. Patients who prefer to avoid systemic hormone exposure altogether can use the GHK-Cu-only formulation and still receive the peptide’s collagen-support benefits.
Semaglutide and tirzepatide are peptide-based metabolic medications that work through appetite and satiety signaling. Semaglutide acts on the GLP-1 receptor; tirzepatide acts on both the GIP and GLP-1 receptors. Combined with nutrition, exercise, and medical follow-up, both can reduce appetite and support meaningful weight loss. FDA-approved branded versions (Wegovy, Ozempic, Zepbound, Mounjaro) have substantial clinical-trial evidence behind them. Compounded versions are not FDA-approved and are not equivalent to the branded products — a distinction we’ll always be transparent about.
Are Peptides Safe?
Safety depends on the specific medication, route, dose, pharmacy source, and your individual medical history. “Peptide” does not automatically mean “safe,” “natural,” or “risk-free,” and we screen every patient accordingly.
Common injection-related side effects can include site redness, bruising, swelling, itching, headache, nausea, flushing, or lightheadedness. Topical GHK-Cu may cause dryness, redness, burning, or irritation in some patients. Weight-management injections carry their own specific risks, including nausea, vomiting, diarrhea, constipation, and — rarely — pancreatitis or gallbladder problems; they are not appropriate for patients with a personal or family history of medullary thyroid cancer or MEN2, and require careful review for patients with a history of pancreatitis, gastroparesis, or eating disorders.

Are Peptides the Same as Hormones or Steroids?
No. Peptides are not anabolic steroids. Anabolic steroids are synthetic derivatives of testosterone with a different mechanism, risk profile, and regulatory status entirely. Peptides are also not automatically the same as hormone replacement therapy, though some — like GLP-1 and GIP — are themselves metabolic signaling hormones. Our peptide and wellness programs are not presented as systemic hormone replacement therapy, but patients still require screening because these medications can affect metabolism, digestion, inflammation, and appetite.
Are These Treatments FDA-Approved?
Some are. Semaglutide and tirzepatide have FDA-approved branded products for specific indications (weight management and/or type 2 diabetes). Compounded versions of these medications are not FDA-approved and should never be described as equivalent to the branded products.
BPC-157 and TB-500 are not FDA-approved for any use — recovery, tendon healing, or otherwise.
Injectable GHK-Cu remains a substance the FDA has flagged for safety concerns in the compounded-injectable setting; topical GHK-Cu formulations fall under a separate, less restrictive review category.
Compounded medications, generally, are not FDA-approved. The FDA does not independently verify compounded products for safety or effectiveness before they reach a patient. That doesn’t mean compounding is inappropriate — it means patients deserve to understand the difference between an FDA-approved commercial drug and a compounded medication prepared for an individual prescription, and we make that distinction clearly in every consultation.
Why Does Sourcing Matter So Much?
Safety depends on the specific medication, route, dose, pharmacy source, and your individual medical history. “Peptide” does not automatically mean “safe,” “natural,” or “risk-free,” and we screen every patient accordingly.
Common injection-related side effects can include site redness, bruising, swelling, itching, headache, nausea, flushing, or lightheadedness. Topical GHK-Cu may cause dryness, redness, burning, or irritation in some patients. Weight-management injections carry their own specific risks, including nausea, vomiting, diarrhea, constipation, and — rarely — pancreatitis or gallbladder problems; they are not appropriate for patients with a personal or family history of medullary thyroid cancer or MEN2, and require careful review for patients with a history of pancreatitis, gastroparesis, or eating disorders.
How Long Do These Treatments Take to Work?
BPC-157 + TB-500: Not an immediate pain medication. Patients who respond typically notice gradual change over several weeks, especially alongside proper wound care, nutrition, and physical therapy. We recommend a 4–5 week reassessment.
- NAD+ + B12: Some patients report improved energy or mental clarity within days; others notice little change. Persistent fatigue should be medically evaluated rather than assumed to be an NAD+/B12 issue, since fatigue has many possible causes.
- GHK-Cu (topical): Skin tolerance is usually clear within the first several days. Texture and tone improvements are gradual and typically develop over weeks to months, especially combined with other skin-quality treatments.
- Semaglutide / Tirzepatide: Appetite changes may begin within days to weeks, but meaningful weight loss develops gradually over months as dosing is titrated. These medications work best paired with adequateprotein intake, resistance training, and ongoing follow-up. Weight regain is possible if treatment stops without a maintained lifestyle plan.
Who Needs Additional Review Before Starting?
You’ll need additional review before treatment if you are pregnant, breastfeeding, or trying to conceive; preparing for surgery or anesthesia; already using a GLP-1 medication, insulin, or a sulfonylurea; using blood thinners; actively infected; undergoing cancer treatment or immunosuppressed; subject to competitive drug testing; or have a history of pancreatitis, gallbladder disease, gastroparesis, bowel obstruction, kidney or liver disease, serious allergic reactions, an eating disorder, a clotting disorder, stroke, heart attack, estrogen-sensitive cancer, or medullary thyroid cancer/MEN2. A “yes” to any of these doesn’t automatically rule out treatment — it means we review it with you before prescribing. If you’re interested specifically in the estradiol-containing GHK-Cu cream, see the additional considerations above, which apply on top of this list.
When Should I Call the Office or Seek Urgent Care?
Call our office for worsening side effects, persistent nausea or vomiting, dizziness, rash, spreading redness, drainage, fever, or if you have an upcoming surgery, sedation, or endoscopy.
Seek urgent medical care for severe abdominal pain, persistent vomiting, dehydration, fainting, chest pain, shortness of breath, a severe allergic reaction, rapidly spreading redness, or any symptom that feels severe.
Bottom Line
Peptides are medically legitimate molecules, and some peptide-based medications are well studied and FDA-approved for specific conditions. At the same time, many wellness and recovery peptide protocols are still emerging, and the quality of evidence varies substantially by treatment. Our approach at West Annapolis Medical Spa is to avoid hype, avoid unsupervised online sourcing, screen patients carefully, use licensed prescription-based sourcing, and set realistic expectations. These treatments may support recovery, skin quality, energy, or weight-management goals in the right patients — but results vary, and no specific outcome is guaranteed.
