The Lowdown on Tirz Research

Tendon/Ligament Repair

BPC-157 accelerates healing of tendons and ligaments by enhancing collagen organization and angiogenesis, restoring function faster than controls.

Supporting Study: Chang, C. H., et al. (2011). “The promoting effect of pentadecapeptide BPC 157 on tendon healing involves tendon outgrowth, cell survival, and cell migration.” Journal of Orthopaedic Research, 29(3), 406–411.

Findings: In an Achilles tendon injury model, BPC-157 (10 µg/kg intraperitoneally) significantly improved tendon healing, increasing collagen fiber organization and biomechanical strength by 50% compared to controls within 14 days. It promoted fibroblast migration and VEGF expression, enhancing angiogenesis.

BPC-157 speeds up muscle repair, reducing inflammation and improving strength post-injury.

Supporting Study: Novinscak, T., et al. (2008). “Gastric pentadecapeptide BPC 157 as an effective therapy for muscle crush injury in the rat.” Journal of Pharmacological Sciences, 108(1), 29–37.

Findings: In rats with induced muscle crush injuries, BPC-157 (10 µg/kg intraperitoneally or locally) reduced edema and inflammation within 24 hours and restored muscle function by day 7, significantly faster than controls. It enhanced myoblast proliferation and reduced oxidative stress.

Benefit: BPC-157 promotes rapid skin wound closure by increasing fibroblast activity and reducing scar tissue.

Supporting Study: Sikiric, P., et al. (2016). “Pentadecapeptide BPC 157 and its effects on healing and tissue regeneration.” Current Pharmaceutical Design, 22(14), 2036–2043.

Findings: In rat models of deep skin burns and excisional wounds, BPC-157 (0.01–10 µg/kg, topical or systemic) accelerated wound closure by 30–40% within 7–14 days, enhancing fibroblast activity and collagen deposition while minimizing scar formation.

Benefit: BPC-157 heals gastrointestinal injuries, protecting mucosal linings and repairing ulcers or fistulas.

Supporting Study: Sikiric, P., et al. (1997). “Pentadecapeptide BPC 157 interactions with adrenergic and dopaminergic systems in mucosal protection in stress.” European Journal of Pharmacology, 332(1), 23–33.

Findings: In rats with stress-induced gastric ulcers or NSAID damage, BPC-157 (0.01–10 µg/kg, oral or intraperitoneal) restored mucosal integrity within days, reducing ulcer size by 80% compared to controls and protecting against epithelial damage.

Tirz enhances insulin secretion while reducing glucagon release, supporting improved glycemic control in research models.

Supporting Study: Frias, J. P., et al. (2021). “Tirzepatide versus Semaglutide Once Weekly in Patients with Type 2 Diabetes.” New England Journal of Medicine, 385(6), 503–515.
Findings: Tirz significantly lowered HbA1c levels compared to semaglutide, demonstrating superior glucose regulation.

Description

Tirz is a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. In research, it is studied for its ability to improve glycemic control, promote significant weight reduction, and regulate appetite through enhanced insulin secretion and reduced glucagon activity.

It has been investigated for applications in obesity management, type 2 diabetes research, and metabolic health. By activating both GIP and GLP-1 pathways, Tirz enhances insulin sensitivity, lowers blood glucose levels, and supports weight loss through appetite regulation and improved energy metabolism.

Key Benefits:

  • Supports research on glucose regulation and insulin sensitivity.
  • Aids studies on weight loss, appetite control, and obesity management.
  • Contributes to research on type 2 diabetes and metabolic syndrome.
  • Promotes fat reduction and improved body composition.
  • Explored for roles in cardiovascular and metabolic health.

FAQ

What are peptides?
Peptides are short chains of amino acids (typically 2–50) studied for their roles as signaling molecules that influence biological processes. Unlike proteins, peptides are smaller and often act as hormones, growth factors, or receptor agonists/antagonists. In research settings, they are explored for their potential to modulate cellular functions, such as metabolism, tissue repair, and immune response

We stand by our peptide quality with an industry-leading 90-day return policy and a guarantee that our peptides meet or exceed 99% purity. We have an in house lab that can allow for rapid testing via UHPLC to ensure that every batch can be tested quickly and product shipped out.

Peptides, naturally occurring chains of amino acids in the body, are legal to purchase for research purposes in many regions, including the U.S., when sold as research chemicals.
Our peptides, are stored at 0°C to ensure maximum stability and potency for research purposes. This cold storage preserves their integrity, maintaining quality for your experiments.
