What are peptides?
Peptides are short chains of amino acids that act as signaling molecules in the body, influencing a wide range of biological processes.
Read answer StorageDo peptides need refrigeration?
It depends on the state. Lyophilized powder is often stable at room temperature, while reconstituted (liquid) peptides are usually refrigerated. Always follow the specific product's guidance.
Read answer General PeptidesAre peptides safe?
Safety depends entirely on the specific peptide, the dose, the route, and the person. There is no general "peptides are safe" answer.
Read answer ReconstitutionWhy is bacteriostatic water used?
Bacteriostatic water is sterile water with a small amount of benzyl alcohol, which inhibits bacterial growth so a reconstituted vial can be used over multiple doses.
Read answer StacksWhat is a peptide stack?
A peptide stack is a combination of peptides studied together in a related context, often because their mechanisms might complement each other.
Read answer General PeptidesAre peptides steroids?
No. Peptides and steroids are fundamentally different classes of compounds with completely different structures and mechanisms.
Read answer Injection BasicsWhat is a subcutaneous injection?
A subcutaneous injection delivers a substance into the fatty tissue just beneath the skin — not into the muscle.

Read answer StorageDo peptides expire?
Yes — peptides lose potency over time. Lyophilized powder lasts longer than reconstituted liquid, but neither lasts forever.
