Retatrutide kit: what does each pack contain and which one to choose?

Single vial, kit with reconstitution materials, or three-vial pack: PeptiLine offers retatrutide (R3) in six formats. This page details the contents of each, its cost per milligram, and when it makes the most sense. All vials are lyophilized, sealed, and covered by a published Janoshik report.

R10 Pack – €69.9060mg pack – €270 delivered

All six formats in one table

There are also two duo kits that combine retatrutide with GHK-Cu 50 mg:GLOW1 Pack(10 mg, €89.90) andGLOW2 Pack(20 mg, €129.90).

What an R10 or R20 Pack contains

The R10 Pack and the R20 Pack include the retatrutide vial and the necessary equipment to reconstitute it in the laboratory:

• the bottle of lyophilized retatrutide (10 or 20 mg), lot number printed on the label;
• of thebacteriostatic water(benzyl alcohol 0.9%), the reconstitution solvent;
• sterile single-use syringes;
• disinfectant pads.

No kit contains medical instructions, dosage information, or protocols; these are laboratory supplies. The reconstitution method is described in our article.reconstitute a lyophilized peptide.

Bottle only or kit?

If you don't already have the equipment, the kit is the simplest option: the R10 Pack costs €10 more than the bottle alone. If you already have bacteriostatic water and syringes, buy the bottle alone. For a more complete kit, theReenactment Pack(€14.90) contains a reconstitution syringe, 10 31G 6mm syringes, bacteriostatic water, two pairs of nitrile gloves and disinfectant swabs.

The 3-bottle packs

The three-vial packs offer the lowest price per milligram: €5.00 for the 30 mg pack (€150 instead of €179.70) and €4.50 for the 60 mg pack (€270 instead of €299.70). The 60 mg pack exceeds the €160 threshold: delivery is free.

Three separate bottles rather than one large bottle: each bottle remains sealed until used. Once reconstituted, a bottle can be kept for a few weeks in the refrigerator (seeconservation of retatrutide): it's best to only open what is needed.

10 mg or 20 mg?

The content is the same peptide, only the quantity changes. The 20 mg is cheaper per milligram (€5.00 vs. €5.99); the 10 mg is more suitable if the reconstituted quantity needs to be used quickly. Both formats have their Janoshik ratios: three batches of 10 mg and three batches of 20 mg, all above 99.4% purity (see the table).
