Frequently Asked Questions
Why are Northstar peptides labeled “Not for Human Consumption”?
Northstar Labs peptides are sold exclusively for in-vitro research and laboratory use only. This legal designation aligns with state and federal research-chemical regulations. We are not a pharmacy, nor do we provide medical advice.
Are your products lab-tested?
Yes. Every batch is independently tested by third-party laboratories and HPLC-verified for ≥98% purity. Certificates of Analysis are available on request.
Do you provide dosing or medical guidance?
No. All products are strictly for research use. We cannot provide dosing, therapeutic, or medical advice of any kind.
Why does the peptide powder in the vial appear clumpy or powdery?
This is normal. Peptides are shipped in lyophilized (freeze-dried) form, which may appear as a loose powder, a dense pellet, or scattered flakes. This is a cosmetic artifact of shipping and does not affect purity or potency.
Why does it take time to dissolve peptides during reconstitution?
Lyophilized peptides dissolve best with gentle swirling — not vigorous shaking — in bacteriostatic water. Some peptides dissolve within seconds; others may take a few minutes.
How should peptides be stored?
Unreconstituted peptides should be stored in a cool, dry place (room temperature is generally fine short-term). Once reconstituted, store in the refrigerator. For long-term storage, freeze at -20°C.
