Product Name: DSIP (Delta Sleep-Inducing Peptide) CAS Number: 62568-57-4 Molecular Formula: C₃₅H₄₈N₁₀O₁₅ Purity: ≥98% (HPLC verified) Formulation: Lyophilized powder (typically available in 5mg, 10mg vials)
🔬 Biological Characteristics
DSIP is a somnogeneric nonapeptide (9-amino acid peptide) endogenously produced in the brain and peripheral tissues. It readily crosses the blood-brain barrier and acts as a neuromodulator by influencing GABAergic, glutamatergic, and other neuronal systems.
⚙️ Key Functions & Research Applications
Sleep Regulation: Promotes deep slow-wave sleep (SWS) and modulates sleep architecture, though effects may vary between native peptide and synthetic analogs. Unlike hypnotics, it enhances sleep quality rather than inducing drowsiness.
Stress Modulation: Exhibits stress-protective properties by reducing basal corticotropin (ACTH) levels, inhibiting cortisol release, and mitigating stress-induced metabolic disorders in preclinical models.
Endocrine Regulation: Stimulates luteinizing hormone (LH) secretion and supports hormonal balance without disrupting glucose homeostasis.
Neuroprotection & Antioxidant Effects: Enhances mitochondrial oxidative phosphorylation efficiency and demonstrates potential in reducing oxidative stress in cellular studies.
📊 Product Features
Stability: Lyophilized form ensures stability under -20°C to -80°C storage; reconstitute with sterile solvent (e.g., bacteriostatic water) for research use.
Purity: ≥98% purity confirmed via HPLC, suitable for in vitro and preclinical research applications.
Research Utility: Investigated in studies on sleep disorders, stress physiology, endocrine regulation, and neuroprotective mechanisms.
⚠️ Disclaimer
For Research Use Only: Not approved for human or veterinary clinical use. Handling requires adherence to standard peptide research protocols.
None of our HGH lines are inherently better than the other. Each batch comes with a corresponding test report. Purity and dimer can be a decent proxy for “quality”, you want purity as high as possible and dimer as low as possible. The main factor to consider in our opinion, is the price per IU. Supreme is usually the best bang for buck option. Historically, Supreme & Deluxe have shown lower dimer content, although this may not always be the case, so of course reference the corresponding test reports.
For HGH, we typically recommend 1ml for every ~10 IU in the vial. If a batch tests at an average of 290 IU per kit, that is an average of 29 IU per vial, and we’d recommend 2.9ml of bacteriostatic water. This will make the syringe math similar to a traditional 100 iu kit with 1ml of solution For peptide reconstituion, you can use our amazing Dosage Calculator.
Not necessarily. If you look through all our lab reports, particularly the ones with multiple test reports in a single batch, you will see that the intra-batch variance can actually be quite high. When you purchase a batch, you can expect some of the vials in your kit to be as much as 5-15% +/- whatever the corresponding lab test reflects. This is simply the reality of product that is not made to the same standards as pharmaceutical grade growth hormone. To state otherwise would be disingenous. There can also be a high variance in the dimer content intra-batch. (For Example: Economy B, Deluxe A, etc) Over time, we’ve increased the volume of samples analyzed for each batch, to provide more transparancy regarding the potential for intra-batch variance. If you use the average IU figure provided on each product, your dosage should average out over time, so don’t overthink your administration protocol too much. We know it can be a bit overwhelming with all the different numbers provided. That said, don’t hesitate to reach out if you need specific guidance on dosage or reconstitution.
Yes! We offer store credit for quantitative testing of total IU/Purity (ie Janoshik testing), and for personal IGF-1 test results. Please email for more information. *TERMS APPLY*

Regenerative Peptide Combo | Musculoskeletal Repair + Whole Body Recovery
(5 mg BPC-157 + 10 mg TB-500 per bottle)
Overview:
This powerful peptide blend combines BPC-157 and TB-500, two of the most researched peptides for tissue regeneration, anti-inflammatory and injury repair. When used together, BPC and TB-500 create a synergistic effect that supports local healing and systemic repair mechanisms throughout the body.
Ideal for athletes, active individuals or those recovering from soft tissue injuries, this blend is often used in treatment regimens for tendinitis, ligament injuries, muscle strains and post-surgery recovery.
Semaglutide is a GLP-1 receptor agonist originally developed for type 2 diabetes and now widely used in medically guided weight loss and metabolic optimization protocols. By mimicking the natural hormone GLP-1, it helps regulate blood sugar, reduce appetite, and delay gastric emptying — resulting in sustained fat loss, improved insulin sensitivity, and enhanced satiety.
This product contains Semaglutide in lyophilized (freeze-dried) powder form, requiring reconstitution before use.
