The Stasis ION™ Technology.
MicroAmino's pre-filled pens, cartridges and nasal/oral sprays are made with Stasis ION™, a liquid excipient built from citric acid and the amino acids lysine and arginine. It is designed to help keep peptides stable in solution and help them cross tissue. The evidence so far is early lab work; the only crossing test used pig skin in a dish. This page sets out what was tested, what it showed, and what it does not show.
Everything below is preclinical: lab and animal tests of the excipient, for research context only. No human studies have been done. It is not a medical, therapeutic or performance claim about any product. Research Use Only — professional / physician use only.
What the stability test showed.
An outside lab stored one short test peptide (2–5 amino acids, 10 mg/mL) in Stasis ION™ and measured it by HPLC. The lab did not name the peptide.
| Condition | Result | Source |
|---|---|---|
| Room temperature, 1 month | 101.1% | Outside lab |
| Room temperature, 2 months | 101.1% | Outside lab |
| Room temperature, 3 months | 101.2% | Manufacturer's own data |
| Room temperature, 4 months | 101.9% | Manufacturer's own data |
| 37 °C for 3 days | 105.8% | Outside lab |
| Sunlight for 10 days | 104.6% | Outside lab |
Percent of the intended starting amount. The starting amount itself was not measured.
- Why over 100%? A peptide cannot gain strength. The test method read 112% on a known sample, so these results mean no large loss was seen — not that 100% was kept.
- One test peptide. Longer peptides such as BPC-157 or the GLPs were not tested.
- Not a shelf-life claim for any MicroAmino product.
- Not a formal (ICH) stability study. Temperature and humidity control were not reported.
The other results — and their limits.
These results come from one outside lab report. Repeats were not reported. None involved people.
| Test | What was done | Result | What it does not show |
|---|---|---|---|
| Permeation | Peptide applied to 0.5 mm pig skin in a lab dish, with and without Stasis ION™ | About 57× more crossed in 24 h: 4.6% of the peptide, against 0.08% without | Not living tissue, not mucosa, not people, not a bioavailability figure |
| Particle size | Light-scattering size test of the peptide solution | Two size peaks: about 200–300 nm and 5–10 nm | That the particles carry peptide or pass through mucus is untested |
| Oral dosing in mice | Fluorescent-labelled peptide given by mouth, imaged after 1 hour | Signal in the stomach, intestine, liver, lungs and kidneys; little in the control group | Shows where the dye went, not that intact peptide arrived; no blood levels |
| Cell safety | Cells exposed to the excipient for 24 and 48 hours (CCK-8 test) | 80–100% of cells stayed viable | Cell type and dose were not reported |
| Ingredients | Citric acid, L-lysine, L-arginine | All three are long-used food and pharmacopeial (USP/NF) ingredients | Not an approval or certification of the excipient itself |
Supplier certification.
Stasis ION™ comes from a supplier whose facility holds NSF/ANSI 455-2, a GMP certificate for dietary supplements (capsules, gummies and ingestible liquids).
- It covers that facility only.
- It does not cover the excipient itself or MicroAmino's finished products.
- Every MicroAmino batch ships with a third-party COA.
Scope of the certificate
Dietary-supplement GMP covering 21 CFR Parts 111, 117 and 11. Listed product categories: capsules, gummies and ingestible liquids.
Made with Stasis ION™.
Every pre-filled format in the MicroAmino catalog uses the Stasis ION™ excipient.
