1. Retatrutide 10mg  CAS 2381089-83-2 · MW 4731.33 · C₂₂₁H₃₄₂N₄₆O₆₈

Triple-Agonist Metabolic Peptide (GLP-1/GIP/GCGR)

Retatrutide (LY3437943) is a novel triple-agonist peptide developed by Eli Lilly that simultaneously activates the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon-like peptide-1 receptor (GLP-1R). It binds human GCGR, GIPR, and GLP-1R with EC₅₀ values of 5.79, 0.0643, and 0.775 nM, respectively. In phase 2 clinical trials, retatrutide produced mean body weight reductions of 15–24% over 48–72 weeks. Researched for potent fat oxidation, appetite suppression, metabolic rate enhancement, and body recomposition. Form: lyophilized powder.

2. Melanotan II 10mg  CAS 121062-08-6 · MW 1024.18 · C₅₀H₆₉N₁₅O₉

Melanocortin Receptor Agonist (MC1R–MC5R)

Melanotan II (MT-II) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It acts as a potent non-selective melanocortin receptor agonist with high affinity for MC1R, MC3R, MC4R, and MC5R subtypes. Sequence: Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂. Half-life approximately 33 hours. Researched for rapid melanogenesis (tanning/pigmentation without UV), appetite modulation, and libido pathway signaling. Form: lyophilized powder.

3. Human Growth Hormone (HGH/Somatropin) 10 IU  CAS 12629-01-5 · MW 22,124 · 191 amino acids

Recombinant Growth Hormone — GH Axis

Recombinant human growth hormone (rhGH/somatropin) is a 191-amino-acid single-chain polypeptide identical to endogenous pituitary-derived GH. It binds the growth hormone receptor (GHR) to activate the JAK2/STAT5 signaling cascade, stimulating hepatic IGF-1 production, lipolysis, protein synthesis, and linear growth. Researched for lean tissue accrual, fat metabolism, recovery acceleration, sleep quality, and anti-aging effects. Form: lyophilized powder, 10 IU per vial.

4. IGF-1 LR3 1mg  CAS 946870-92-4 · MW ~9,111 · 83 amino acids

Long-Acting Insulin-Like Growth Factor — Anabolic Signaling

IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a modified form of human IGF-1 with an arginine substitution at position 3 and a 13-amino-acid N-terminal extension. This modification dramatically reduces binding to IGF-binding proteins (IGFBPs), extending its half-life from ~15 minutes (native IGF-1) to 20–30 hours. IGF-1 LR3 activates the IGF-1 receptor (IGF-1R) to promote PI3K/Akt and MAPK/ERK signaling cascades. Researched for muscle cell hyperplasia, tissue repair, lean mass hypertrophy, enhanced nutrient partitioning, and vascularity. Form: lyophilized powder.

5. GHK-Cu 100mg  CAS 49557-75-7 · MW 403.93 · C₁₄H₂₄CuN₆O₄

Copper Tripeptide Complex — Collagen & ECM Remodeling

GHK-Cu (glycyl-L-histidyl-L-lysine:copper(II)) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It functions as a potent activator of tissue remodeling via upregulation of collagen I, III, and IV synthesis, elastin production, glycosaminoglycan accumulation, and metalloproteinase modulation. GHK-Cu also promotes decorin expression and integrin signaling in dermal fibroblasts. Researched for skin firmness and elasticity, wound healing acceleration, scar reduction, anti-inflammatory effects, and hair follicle stimulation. Form: lyophilized powder, 100mg per vial.

6. NAD+ 500mg  CAS 53-84-9 · MW 663.43 · C₂₁H₂₇N₇O₁₄P₂

Nicotinamide Adenine Dinucleotide — Cellular Energy & Longevity

NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a critical coenzyme present in every living cell that functions as an electron carrier in mitochondrial oxidative phosphorylation and as a substrate for NAD+-consuming enzymes including sirtuins (SIRT1–7), PARPs, and CD38. NAD+ levels naturally decline with age, and replenishment is researched for its role in mitochondrial biogenesis, DNA repair, sirtuin-mediated gene regulation, circadian rhythm maintenance, and cellular senescence pathways. Researched for anti-aging, cognitive resilience, metabolic efficiency, liver protection, and energy restoration. Form: lyophilized powder, 500mg per vial.

7. Testosterone Cypionate 250mg/ml  CAS 58-20-8 · MW 412.61 · C₂₇H₄₀O₃

Long-Ester Androgen — Anabolic Foundation

Testosterone cypionate is a long-acting esterified form of testosterone (cyclopentylpropionate ester) that provides sustained androgen release over 7–10 days per injection via intramuscular depot. It binds the androgen receptor (AR) to regulate nitrogen retention, protein synthesis, erythropoiesis, bone mineral density, and secondary male characteristics. In this stack, it serves as the androgenic/anabolic base supporting strength, lean tissue maintenance, recovery, libido, and overall hormonal milieu during intensive research protocols. Form: oil-based injectable, 250mg/ml, 10ml per vial.
