Rebody Health is the better fit when you want named pharmacy partners, several administration routes, and full package details before you start. System Labs is a close match when its current intake and public testing explanation appeal to you. Their headline prices are nearly identical on several treatments. Route, package, and disclosure decide the stronger choice.
Prices and public product details were checked August 23, 2026. Both companies can change an offer, package, or renewal price after that date.

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 |
| Public routine | 50 mg three times weekly for eight weeks | Follow the prescribed directions on the current label |
| 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, supply period, and current routine 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, concentration, and prescribed routine 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 on the current Rebody route 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 prescribed spray volume and daily frequency can differ.
Rebody currently wins the first-price comparison and offers a direct route guide beside the product. System Labs gives a clear concentration and bottle size. The buyer should verify the current directions before comparing cost per day.

Sermorelin: injection and needle-free routes
Both providers list Sermorelin injection at the same first and renewal headline prices: $109 for the first month and $219 after that at System Labs, compared with $109.50 and $219 at Rebody.
The difference appears in route choice and package detail.
| Rebody Health | System Labs | |
|---|---|---|
| Injection | 1 mg/mL, 30-day package, $109.50 first month, then $219 | 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 |
System Labs has a 50-cent lower injection opening price. That difference should not decide the purchase. Compare total amount, concentration, prescribed dose, and administration route.
Rebody has the stronger public route family. A buyer can compare 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 the exact dosage form and dose need to match before making a value claim.

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 30 mL package for 30 days. System Labs showed the price and treatment but needs a matched concentration and package check before a cost-per-milligram comparison. Rebody wins the first-month headline by $4.50. 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.

Provider review and ongoing access
Both services begin online. Rebody uses a product-specific intake followed by a licensed provider review. The displayed price includes the visit, medication when prescribed, shipping, and provider messaging. The product pages state that a patient receives a refund if the provider 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 public experience requires a broad annual testing membership for the treatments compared here. A provider can still request information or testing when the patient's history or selected treatment calls for it.
Pharmacy and testing disclosures
Rebody names three pharmacy partners on its homepage: Strive Pharmacy, The Pharmacy Hub, and Epiq Scripts. The current public non-GLP products compared in Rebody's local catalog list Strive. A pharmacy partner list does not mean that every product uses every partner.
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 gives the stronger public explanation of testing categories. Rebody gives the stronger public pharmacy-identity disclosure. Neither fact proves that one finished prescription works better.
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:
- It names pharmacy partners publicly.
- It offers three NAD+ routes and three Sermorelin routes.
- 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.
For most buyers comparing the full experience, Rebody is our pick. System Labs remains a close alternative, especially when its testing explanation or current intake is the deciding factor.
