🧠 Biological Functions
As a pleiotropic neuropeptide, oxytocin acetate modulates:
Social Behavior: Enhances pair bonding, trust, and maternal-infant attachment in rodent models (0.1 mg/kg SC increases social interaction time to 71.6±4.3s vs. 56.9±4.1s in controls)
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*

Retatrutide is a next-generation triple incretin agonist, targeting GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and Glucagon receptors simultaneously. This unique triple-action mechanism offers a powerful blend of appetite suppression, fat oxidation, and energy regulation, positioning Retatrutide at the forefront of advanced weight management and metabolic enhancement therapies.
This product is supplied as a lyophilized powder and requires reconstitution before use.

Tirzepatide is a cutting-edge dual incretin agonist that mimics both GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) — two key hormones involved in regulating blood sugar, satiety, and energy balance. This unique mechanism allows for enhanced appetite suppression, improved insulin sensitivity, and significant fat loss when combined with proper nutrition and lifestyle protocols.
Available as a lyophilized powder, Tirzepatide requires reconstitution prior to use.

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.

MOTS-c is a naturally occurring mitochondrial-derived peptide that plays a key role in cellular energy regulation, fat metabolism, and glucose control. Often referred to as a “metabolic mini-hormone,” MOTS-c enhances the body’s ability to burn fat, improve insulin sensitivity, and adapt to metabolic stress — making it an ideal peptide for those seeking fat loss, improved endurance, and anti-aging support.
This product is supplied as a lyophilized powder and requires reconstitution prior to subcutaneous injection.
