Testagen is a short, bioregulatory peptide that primarily affects the pituitary gland and, subsequently, the thyroid gland. By acting on these glands, Testagen may help normalize testosterone and thyroid hormone production in specific scenarios. Through its influence on thyroid function, it also has a moderate impact on the immune system. Testagen is often viewed as a peptide that can “reset” the pituitary to a more youthful state, making it of interest in anti-aging research. Current studies explore its potential to boost testosterone, enhance thyroid function, and promote stem cell differentiation to support immune health.

This product is intended as a research chemical only. Not for human use. Peptides will arrive in a lyophilized (powder) form for maximum stability.
The combination of BPC-157 and TB-500 brings together two of the most widely researched peptides in regenerative medicine. When used in tandem, these peptides may synergize to support tissue repair, inflammation regulation, and recovery from musculoskeletal injuries.
BPC-157, a synthetic peptide derived from a protective compound in gastric juice, has demonstrated strong angiogenic (blood vessel-forming) and cytoprotective effects in preclinical studies. It has been shown to accelerate healing in tendons, ligaments, muscles, and even the nervous system. Additionally, BPC-157 may modulate nitric oxide pathways, reduce pro-inflammatory cytokines, and promote gastrointestinal repair.
TB-500, also known as thymosin beta-4, is a naturally occurring peptide involved in cell migration, angiogenesis, and tissue regeneration. It acts primarily through the regulation of actin, a protein essential for cell movement and structure. TB-500 has been studied for its potential to aid in wound healing, reduce inflammation, and promote recovery of soft tissue, including heart, eye, and skin tissue.
Together, BPC-157 and TB-500 may offer enhanced healing capabilities by targeting different but complementary biological pathways. While BPC-157 promotes local repair and protects tissues from damage, TB-500 facilitates cellular movement and regeneration on a broader systemic level. This blend is frequently explored in research models focused on sports injuries, post-surgical healing, and chronic inflammation.
BPC-157 Sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
TB-500 Sequence (fragment of Thymosin β4): Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Gly
Molecular Weight (BPC-157): 1419.53552 g/mol
Molecular Weight (TB-500): ~4963 g/mol
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
