NAD+ injection prices and packages
The monthly-equivalent prices look close. The products are packaged differently.
| Rebody NAD+ injection | System Labs NAD+ injection | |
|---|---|---|
| Public formula | 200 mg/mL | NAD+ injection, 1,000 mg monthly package |
| Package | 6 mL vial | 1,000 mg package; confirm vial volume at checkout |
| Supply period | 56 days | Monthly package |
| First payment | $189 for the first two-month shipment | $89 for the first month |
| First-period monthly equivalent | $94.50 | $89 |
| Renewal | $249 every two months | $149 monthly |
| Renewal monthly equivalent | $124.50 | $149 |
| Shipping and provider review | Included | Included according to the treatment page |
System Labs has the lower first-month entry price. Rebody has the lower renewal price on a monthly-equivalent basis, based on the public packages checked. The cash due is different: Rebody charges for two months at once, while System Labs shows a monthly charge.
Rebody also publishes the concentration, vial size, and supply period together. That makes it easier to understand what the $189 shipment contains. The System Labs page gives a clear total amount and price. Confirm its current volume and concentration during intake before treating the packages as equivalent.

NAD+ nasal spray comparison
The nasal products are the closest match in the two catalogs.
| Rebody NAD+ nasal spray | System Labs NAD+ nasal spray | |
|---|---|---|
| Concentration | 300 mg/mL | 300 mg/mL |
| Bottle | 12 mL in the current Rebody comparison guide | 15 mL |
| Supply | 30 days | Confirm current prescribed supply |
| First price | $59.50 | $69 |
| Renewal | $119 monthly | $119 monthly |
| Shipping | Included | Included |
Rebody has the lower introductory price. Both sites showed the same $119 renewal price. System Labs publicly showed the larger bottle volume in the pages checked. Bottle size alone does not establish a better value because the metered amount and prescribed use can differ.
Rebody has the lower first-month price and links to a guide that compares its NAD+ products. System Labs gives a clear concentration and bottle size. Confirm the supply period before you compare the cost per month.

Sermorelin: injection, nasal spray, and oral options
System Labs lists Sermorelin injection at $109 for the first month and $219 after that. Rebody lists $99 for the first month and $198 after that.
The difference is in the product forms and shipment details.
| Rebody Health | System Labs | |
|---|---|---|
| Injection | 1 mg/mL, 30-day package, $99 first month, then $198 | 9 mg package, $109 first month, then $219 |
| Nasal | 1,000 mcg/mL, 6 mL, 30 days, $159 renewal price | No public Sermorelin nasal product found |
| Oral | 600 mcg mini troche, 30 count, 30 days, $159 renewal price | Oral Sermorelin, $79 first month, then $159 |
Rebody has the lower opening and renewal prices for injection. Compare the total amount, concentration, and whether you prefer an injection, spray, tablet, or troche.
Rebody lets you compare an injection, nasal spray, and mini troche on one site. System Labs offers an injection and an oral option. Its oral first-month price is lower than Rebody's regular troche price, but check the exact tablet form and strength before you compare value.

Glutathione and B12
The public glutathione prices are close:
- Rebody: $74.50 first month, then $149 monthly.
- System Labs: $79 first month, then $149 monthly.
Rebody shows 200 mg/mL in a 10 mL package for 30 days. System Labs showed the price and treatment but did not publish enough package information for a cost-per-milligram comparison. Rebody costs $4.50 less for the first month. The renewal prices match.
The B12 products are not exact equivalents. Rebody sells methylcobalamin B12 at 5 mg/mL in a 10 mL vial, supplied for about 60 days. System Labs lists MIC + B12. MIC formulas commonly contain lipotropic ingredients alongside a B12 form, so the ingredient lists and dose should be compared before the products share one price row.
Review Rebody glutathione injection and the methylcobalamin B12 guide.
Provider review and ongoing access
Both services begin online. Rebody asks questions about the treatment you selected, then a licensed clinician reviews your answers. The displayed price includes the visit, prescribed medication, shipping, and messages with the care team. Rebody states that it refunds your payment if the clinician does not prescribe.
System Labs describes a two-minute intake. A provider reviews the answers and reaches the patient by chat when needed. Its treatment pages include ongoing clinician support, supplies, free two-day shipping, and automatic refills that the patient can pause or cancel.
Neither company requires an annual testing membership for these treatments. A clinician can still request more information or testing based on your history and the treatment.
Pharmacies and prescription testing
Licensed U.S. pharmacies fill Rebody prescriptions. Your clinician sets the dose, timing, and use. Follow your prescription label.
System Labs states that a certified U.S. pharmacy fills its treatments. It also lists potency, sterility, pH, and endotoxin testing. The pages checked did not show the pharmacy name. They did not give enough detail to confirm whether a patient can open a lot-specific report for the exact shipment.
System Labs explains more about the types of pharmacy testing. Rebody explains the formulation and shipment for each treatment. These facts help you understand how each service operates, but they do not compare the results of the prescriptions.
Where System Labs wins
System Labs deserves four clear wins from the pages checked:
- Its NAD+ injection has a lower first-month cash price.
- Its oral Sermorelin has a lower introductory price than Rebody's current regular troche price.
- It explains several testing categories on the public site.
- It states free two-day shipping and a short intake in direct terms.
System Labs is a serious close competitor. A buyer who values those points can reasonably choose it.
Where Rebody wins
Rebody has the stronger case in these areas:
- Licensed U.S. pharmacies fill its prescriptions.
- It offers three NAD+ choices and three Sermorelin choices.
- Its product pages place concentration, package, supply, price, and care inclusions together.
- Its NAD+ injection has a lower renewal cost on a monthly-equivalent basis based on the public offers checked.
- Its NAD+ nasal spray and glutathione injection have lower introductory prices.
- The displayed treatment price includes provider review, medication when prescribed, shipping, and messaging.
Rebody offers more product choices and publishes more shipment details. System Labs is a close alternative when its testing information or short intake matters more to you.
