Retaklik vs Retaklik 2.0: Which Retatrutide Research Pen Should You Choose?
Evora Pharma
Retaklik and Retaklik 2.0 are both retatrutide research pens from Evora Pharma. Here’s how the 20mg, 40mg and 60mg Retaklik pens compare with the single 45mg Retaklik 2.0 on strength, price per mg and documentation.
Both Retaklik and Retaklik 2.0 are pre-filled laboratory presentations of retatrutide, supplied by Evora Pharma for controlled research and R&D evaluation. The compound is the same — what differs is the strength, the number of options, and the price per milligram. This guide sets out the differences so you can pick the right format for your protocol.
The short answer
- Choose Retaklik if you want to match strength closely to your protocol (20mg, 40mg or 60mg), or you need batch-specific Janoshik lab reports on file.
- Choose Retaklik 2.0 if a single 45mg presentation suits your work and you want one of the lowest prices per milligram in the range without moving up to the 60mg pen.

What’s the same
Both products are retatrutide — a multi-receptor investigational compound studied in laboratory settings for GLP-1, GIP and glucagon pathway research. Both are supplied as sealed, pre-filled research pens with:
- Clear product labelling and research-use-only marking
- Batch identification for traceability
- Storage guidance (refrigerate at 2–8°C, protect from light)
- The same UK dispatch, delivery and ordering process
Where they differ
1. Strength options
Retaklik comes in three strengths — 20mg, 40mg and 60mg — so you can match the presentation to the scale of your project. The 20mg pen suits pilot work and method evaluation; 40mg and 60mg suit ongoing or larger projects.
Retaklik 2.0 is a single 45mg presentation. It sits between the 40mg and 60mg Retaklik pens, which keeps ordering simple if 45mg fits your plan.
2. Price per milligram
Retaklik 2.0 works out at roughly £3.11 per mg — cheaper per mg than the 20mg and 40mg Retaklik pens, and close to the 60mg pen (≈ £3.00 per mg) for £40 less up front. If cost per mg matters but you don’t need the full 60mg, Retaklik 2.0 is the middle ground.
3. Lab reports
Independent Janoshik verification reports are currently published for the Retaklik 20mg (99.071%), 40mg (99.278%) and 60mg (99.452%) batches, linked from the lab-reports section of the Evora homepage. If your lab needs third-party purity data on file before purchase, Retaklik is the more documented option today. For Retaklik 2.0 batch documentation, contact us before ordering.
