What is QSC Clavicular Looksmaxxing Stack?
The QSC Clavicular Looksmaxxing Stack is a 7-compound, 70-vial extended investigative research kit combining complementary peptides and compounds across multiple biological pathways. Each compound ships as a 10-vial kit, providing sufficient material for extended multi-month protocol research. The stack targets the GH axis (growth and body composition), melanocortin system (pigmentation), copper peptide biology (collagen and ECM remodeling), mitochondrial bioenergetics (NAD+ and sirtuin activation), metabolic triple-agonist signaling (fat oxidation and appetite), IGF-mediated anabolic pathways (lean tissue and repair), and androgenic/anabolic drive (protein synthesis and nitrogen retention).
Stack Components — 7 Compounds (10 Vials Each)
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.
