Updated 2026-06-04 · X Factor Peptides

Pre-reconstitution

Lyophilized Tesamorelin at −20°C is stable through the printed expiry date. At 2–8°C the shelf life shortens to ~6 months.

Post-reconstitution

After adding bacteriostatic water, store at 2–8°C and use within 30 days. Aliquot before freezing if you intend to store longer.

Reserve sample policy

We retain a −80°C reserve aliquot of every released lot for 24 months. Email [email protected] if you ever question a result.
