Veyvora’s Lean Stack Research Bundle is a defined two-pen research stack pairing Tirzepatide 40 and NAD+ 1000, listed under the Metabolic & Weight category as a “bundle & save” offer with a stated 15% saving versus buying each pen separately, as of 30 August 2026 [2]. Exact GBP pricing and real-time stock status are confirmed at checkout [2]. Both pens are supplied for in-vitro laboratory research.
Key Takeaways
- The bundle pairs Tirzepatide 40 (dual GIP/GLP-1 receptor agonist, 40 mg click pen) with NAD+ 1000 (1,000 mg, 3 mL cellular-energy pen) at a stated 15% saving versus separate purchase, as of 30 August 2026.
- Tirzepatide is studied as a dual GIP/GLP-1 receptor agonist and NAD+ as a cellular-energy coenzyme; each compound’s evidence base is documented under its own study conditions.
- Both pens are supplied for in-vitro laboratory research; tirzepatide is also the active substance of the MHRA-authorised medicine Mounjaro, and the research pen is a separate, unregistered laboratory presentation.

Exact Bundle Identity
Veyvora’s Lean Stack Research Bundle pairs Tirzepatide 40, a dual GIP (glucose-dependent insulinotropic polypeptide) / GLP-1 (glucagon-like peptide-1) receptor agonist in a 40 mg click pen, with NAD+ (nicotinamide adenine dinucleotide) 1000 (a 1,000 mg, 3 mL cellular-energy pen), sold together under the Lean Stack label at a stated 15% saving versus purchasing each pen separately, as of 30 August 2026 [2].
The bundle appears in Veyvora’s Metabolic & Weight category under “bundle & save” and carries the positioning description “Dual-agonist weight management with cellular energy underneath,” which describes the compounds’ receptor targets and research roles [2]. Exact GBP pricing and real-time stock status are confirmed at checkout [2].
The Lean Stack is distinct from two sibling stacks listed on the same page: Advanced Lean Stack (Retatrutide 40 + NAD+ 1000 + Tesamorelin 20, 12% saving) and Metabolic Reset (MOTS-C + SS-31 40 + Tirzepatide 40, 15% saving) [2]. Each sibling stack has its own compound profile and bundle identity, so confirm the exact pen names before ordering.
Before first use, verify a batch CoA against your pen to confirm that the pen in hand matches the identity and HPLC (high-performance liquid chromatography) purity data on the certificate.
Included Components
The Lean Stack Research Bundle contains two pens: Tirzepatide 40, a dual GIP/GLP-1 receptor agonist in a 40 mg click pen, and the NAD+ 1000 research pen, a 1,000 mg, 3 mL cellular-energy pen [1][2]. Both are supplied for in-vitro laboratory research.
| Component | Receptor target / mechanism | Nominal strength | Format | Product link |
|---|---|---|---|---|
| Tirzepatide 40 | Dual GIP/GLP-1 receptor agonist | 40 mg | Click pen | Confirm at checkout [2] |
| NAD+ 1000 | Cellular-energy / NAD+ repletion research | 1,000 mg | 3 mL click pen | Confirm at checkout [1] |
Confirm GBP unit prices for each pen at the product detail or checkout stage [1][2]. Confirm the per-click dosing specification for each pen (click count and micrograms per click) with the operator before ordering.
Tirzepatide 40 and NAD+ 1000 each have their own compound-level evidence base [1][2]. Researchers comparing receptor coverage across compounds may find the retatrutide versus tirzepatide comparison useful before finalising a bundle selection. For post-purchase handling, storage and stability guidance covers the conditions applicable to this pen format.
State of the Evidence
The two compounds in this bundle are studied in separate bodies of literature. Veyvora’s pages present mechanistic descriptions and research context for Tirzepatide 40 as a dual GIP/GLP-1 receptor agonist, studied for its effects on glucose regulation and appetite signalling, and for NAD+ 1000 as a cellular-energy research compound, studied as the coenzyme at the centre of cellular energy metabolism [1][2]. The Lean Stack label “Dual-agonist weight management with cellular energy underneath” describes those two receptor and pathway targets [1].
Published mechanistic data for each compound, sourced from peer-reviewed literature, applies to that compound under the conditions of the study that generated it [1][2]. A laboratory protocol that pairs the two pens studies the GIP/GLP-1 agonism pathway and the NAD+ repletion pathway side by side, each against its own evidence base, with the interaction between them as an open research question.
Researchers weighing receptor coverage across related compounds may find the MOTS-c versus SS-31 comparison useful for understanding the mitochondrial-peptide evidence alongside the Lean Stack. Those whose in-vitro protocol calls for a different compound selection can review Veyvora’s research-peptide catalogue.
Batch Documents and Handling
Every pen in the Lean Stack Research Bundle ships with a batch-specific certificate of analysis (CoA) tied to its batch number, covering compound identity and HPLC purity [2]. Veyvora states that each pen in the Metabolic & Weight range undergoes independent assay before dispatch, with the assay results tied to the specific batch rather than a generic product specification [2]. Researchers can verify a batch CoA against their pen before first use to confirm the batch number matches the supplied documentation.
For how HPLC purity is measured and what the figure reports, see what HPLC purity does and does not prove; identity and endotoxin are reported on their own lines of the certificate [2].
Confirm the shipping-temperature and storage conditions for the Lean Stack bundle from the product detail page or dispatch documentation before purchase [2].
Commercial Terms
Veyvora lists the Lean Stack Research Bundle with a stated 15% saving compared with purchasing Tirzepatide 40 and NAD+ 1000 individually, as of 30 August 2026 [1][2]. The bundle appears under the “bundle & save” label on the Metabolic & Weight category page, confirming active availability at that date [1].
Confirm specific GBP unit pricing, shipping charges, dispatch timeframes and real-time stock status directly from the product detail or checkout page before ordering [1][2]. Request minimum order quantities, wholesale tiers and distributor-specific pricing from Veyvora directly [1][2].
For post-purchase handling requirements, including temperature and storage conditions, see storage and stability guidance. Researchers weighing Tirzepatide 40 against alternative receptor-coverage profiles can consult the retatrutide versus tirzepatide comparison before finalising their bundle selection.

Research Use
Every pen in the Lean Stack Research Bundle, Tirzepatide 40 and NAD+ 1000, is supplied for in-vitro laboratory research, such as receptor-signalling and cellular-energy assays in cell culture and use as an analytical reference material [2]. Not for human or veterinary use. Veyvora’s Metabolic & Weight category and the Metabolic Reset stack page state the same research-use position across the entire range [1][2].
The receptor-agonist language on the product pages describes biochemical mechanism [1][2]. The batch-specific CoA supplied with each pen reports compound identity and HPLC purity for the lot [1][2].
Researchers evaluating mitochondrial peptides such as MOTS-C and SS-31 alongside the Lean Stack can consult the MOTS-c versus SS-31 comparison for mechanism-level differentiation.
