Retatrutide Dual-Chamber Pen 60 mg Multi-Pack Bundle

Retatrutide Pen 60 mg multi-pack bundles are designed for users who prefer maximum convenience and plan to continue their protocol.

Each pen contains:

• 60 mg lyophilized Retatrutide (powder)
• Bacteriostatic water for injection

The components remain separated until activation. The solution is automatically mixed inside the pen upon first use, just prior to administration.

• Triple-receptor activation: targets GLP-1, GIP, and glucagon pathways for enhanced appetite suppression, improved insulin sensitivity, increased energy expenditure, and accelerated fat loss.
• Ready-to-use pen: no vials or reconstitution; simply dial, click, and inject subcutaneously.
• Precision dosing: each click delivers 0.5 mg, with a transparent window showing remaining volume.
• Capacity: 120 clicks × 0.5 mg = 60 mg total.
• Quality: ≥ 99% purity, endotoxin < 0.03 EU/mg, sterilized, tamper-evident, scratch-code verified.

This system combines the reliability of lyophilized peptides with the simplicity of a ready-to-use pen.

Retatrutide is a new weekly weight loss injection that’s still in development. Like other popular GLP-1s, it helps you feel full so you naturally eat less.

The difference is in how it works. Retatrutide has been nicknamed “Triple G” because it activates three key hormones at once: GLP-1, GIP, and GCG (glucagon). This triple effect may make it the most powerful option yet  and early studies back that up. 

In a phase II trial, people lost an average of 24.2% of their body weight in just 48 weeks at the highest dose. That’s more than the results seen with Wegovy (~14.9% at 68 weeks) or Mounjaro (~21% at 72 weeks).

Dosing Information (Based on Clinical Trials)

Retatrutide does not yet have an official approved dosing schedule, as it is still in development. However, phase II studies have used the following titration approach:

• Starting dose: 1 mg or 2 mg weekly
• Dose escalation: Increase every 4 weeks
• Maximum dose studied: 12 mg weekly
• Maintenance dose in studies: varied between 4 mg and 12 mg weekly, depending on individual tolerance and goals

Example escalation from trials:
1-4 weeks → 1 mg
5-8 weeks → 2 mg
9-12 weeks → 4 mg
13-16 weeks → 8 mg
17+ weeks → up to 12 mg (if tolerated)

Notes:

• Always escalate gradually (every 4 weeks) to reduce GI side effects.
• Skip escalation if the current dose is well-tolerated but effective.
• Administer once weekly, same day each week, subcutaneously in the abdomen, thigh, or upper arm.

• Refrigerate at 35-40°F after opening.
• Stable 30 days at 25 °C for travel.
