Advanced Lean Stack

This page sets out what the Advanced Lean Stack contains, how its three-pen composition differs from Veyvora’s lower-tier bundles, and what to confirm before ordering.

Veyvora’s Advanced Lean Stack is a fixed three-pen research bundle comprising Retatrutide 40, NAD+ 1000, and Tesamorelin 20, supplied for in-vitro laboratory research and available through Veyvora’s Metabolic & Weight category, with a stated saving of 12–15% against individual pen prices [1].

The Advanced Lean Stack sits at the highest tier of the Metabolic & Weight range, above the two-pen Lean Stack (Tirzepatide 40 plus NAD+ 1000), because it adds Retatrutide 40, a triple GIP (glucose-dependent insulinotropic polypeptide)/GLP-1 (glucagon-like peptide-1)/glucagon agonist that the two-pen configuration does not include [1]. Each pen is independently assayed, shipped cold within 24 hours in gel-packed insulated cartons, and accompanied by a batch-specific certificate of analysis (CoA) on request [2][3].

Key Takeaways

• The Advanced Lean Stack bundles three independently assayed pens, Retatrutide 40 mg, NAD+ 1000 mg, and Tesamorelin 20 mg, at 12–15% below the combined individual prices.
• All three pens are supplied for in-vitro laboratory research; retatrutide and tesamorelin have no registered medicine in the SAHPRA register, and the pens are laboratory presentations.
• The exact ZAR bundle price is shown on the Veyvora product page; confirm it before ordering.
• Each pen ships cold within 24 hours with a temperature-indicator strip; verify the batch number against its CoA before any laboratory use.

The Advanced Lean Stack Research Bundle contains three independently assayed multi-dose pens, Retatrutide 40 mg, NAD+ 1000 mg, and Tesamorelin 20 mg, each supplied as a sealed 3 mL barrel with 300 audible clicks, 10× 31G 6 mm pen needles, a printed dosing card, and a CoA available on request [1][2][3].

Retatrutide 40 is a triple GIP/GLP-1/glucagon agonist and the newest generation of incretin-class metabolic research peptides [1]. NAD+ (nicotinamide adenine dinucleotide) 1000 delivers high-dose substrate for cellular-energy and longevity research at 3.33 mg per click [2]. Tesamorelin 20 is a stabilised growth-hormone-releasing factor analogue used in visceral-fat research at 67 µg per click [3].

The shared click-pen format removes the need for manual reconstitution and syringe-based unit conversions, which cuts a common source of preparation error in laboratory settings. For correct storage conditions prior to in-vitro use, consult Veyvora’s research-peptide storage and stability handling guidance.

Every pen in the Advanced Lean Stack ships with a batch-specific CoA reporting identity and HPLC (high-performance liquid chromatography) purity. Veyvora states that purity is verified above 98% using HPLC, mass spectrometry, and endotoxin assay before dispatch (Veyvora testing specification, 2026) [1]. Match the batch number printed on each pen against its CoA before beginning any in-vitro work. For a precise account of what HPLC purity does and does not prove, including how identity and sterility are reported by their own tests, consult Veyvora’s dedicated assay explainer.

Cold-chain handling follows a consistent specification across the NAD+ 1000 and Tesamorelin 20 pages: pens are dispatched within 24 hours in gel-packed, insulated cartons using 2–8 °C mailers fitted with a temperature-indicator strip [2][3]. A green strip on arrival confirms the cold chain held; query the order before use if the strip has tripped. The Metabolic & Weight category page presents batch-specific CoAs and cold-chain dispatch as the two assurances of content and condition for each pen [1].

CoA availability is listed as “on request” on the NAD+ 1000 and Tesamorelin 20 individual pages. Confirm before ordering whether Veyvora includes CoAs in the box or issues them digitally for the bundle [2][3]. Full research-peptide storage and stability handling guidance, covering temperature ranges, light exposure, and post-receipt shelf life, is available separately and should be reviewed before pens are logged into a laboratory inventory.

Every pen in the Advanced Lean Stack is supplied by Veyvora for in-vitro laboratory research, such as receptor-binding and signalling assays, cell-culture work and use as analytical reference material [1][2][3]. Not for human or veterinary use. Tirzepatide is the active substance of the SAHPRA-registered medicine Mounjaro; retatrutide and tesamorelin have no registered product in the SAHPRA register as of 2026, and the three pens in this bundle are laboratory presentations [4].

The week-by-week click schedules referenced in Veyvora’s dosing guide are research titration references for laboratory work [1].

Before committing any pen to laboratory use, verify your batch against its CoA to confirm the batch number matches the independently assayed certificate. To understand how HPLC purity above 98% is measured and reported, see what HPLC purity does and does not prove.
