Frequently Asked Questions

USP Grade MCT oil is the carrier oil. The only solvents used are Benzyl Alcohol & Benzyl Benzoate (BA & BB).
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.
No, you must purchase it seperately .
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.
