Customer Reviews
Isabel — ★★★★★
Fourth pen. Every batch is identical. The reta effect on metabolism is something you can measure (higher resting energy expenditure) and the pen format means I never skip a dose. Peptex quality is perfect.
Astrid L. — ★★★★★
Switched from the vial to the pen mid-cycle. Identical effects, zero disruption. The pen format makes sense especially for retat which requires careful weekly dosing. No room for reconstitution errors.
sam.w — ★★★★★
Ordered both the tirze and retat pens from peptex. Tried tirzepatide first for 3 months, then switched to retat. The pen format made the transition seamless. Both pens are excellent quality.
Damien — ★★★★★
Third pen order. The triple agonist mechanism (GLP-1 + GIP + glucagon) delivers results that tirze alone couldn't match for me. Having it in a pen format removes the last friction point. Peptex quality is excellent.
Eva M. — ★★★★
Effective product in a convenient format. The thermogenic effect from the glucagon component is more noticeable than with tirzepatide pen. Minor: wish the pen capacity was slightly larger for higher dose phases.
