Retatrutide Peptide Vials: 10mg, 15mg, 20mg & 30mg Compared (GLP-3 Research Guide)
Researchers buy Retatrutide (LY3437943, GLP-3 triple agonist) in several vial sizes—most commonly 10mg, 15mg, 20mg, and 30mg. Choosing the right size affects cost-per-mg, storage, and workflow. This guide compares each size objectively so labs can match purchase format to protocol demands. Research Use Only. Not for human use.
Quick Picks
-
10
10mg Vial — Pilot Work
Best for method development, short studies, and minimizing waste.
-
15
15mg Vial — Flexible Mid-Range
Balances cost and volume when 10mg is tight but 20mg is overkill.
-
20
20mg Vial — Standard Choice
Popular for ongoing projects; strong value per mg without oversizing.
-
30
30mg Vial — Scale & Efficiency
Lowest cost-per-mg for long-term or multi-arm work; plan storage carefully.
Why Vial Size Matters
-
Dosing Precision & Waste
Right-sizing reduces unnecessary reconstitutions and keeps each vial aligned to the actual amount needed per run.
-
Stability & Storage
Smaller vials reduce open/close cycles. Regardless of size, follow low-temp, low-moisture handling. See our peptide storage guide.
-
Cost-Per-mg & Procurement
Larger vials (e.g., 30mg) typically deliver better economics per mg and fewer shipments to manage.
Retatrutide Vial Comparison (10mg–30mg)
| Vial Size | Best For | Advantages | Considerations |
|---|---|---|---|
| 10mg | Pilot studies, method validation | Lowest commitment; minimizes waste; easy storage | May need multiple vials for longer projects |
| 15mg | Short-to-mid projects | Flexible middle ground when 10mg is tight | Less common; check stock lead times |
| 20mg | Ongoing research tracks | Good value per mg; common lab “standard” size | Plan storage for partials if not used quickly |
| 30mg | Long-term or multi-arm work | Lowest cost-per-mg; fewer purchase events | Higher upfront cost; larger reconstitution volume |
Selection Framework
Early-phase → 10mg/15mg. Mid-scale → 20mg. Extended projects / efficiency → 30mg. All formats are RUO and should include batch COAs and ≥99% purity verification.

FAQ: Sizes, Purity & GLP-3 Basics
Is GLP-3 the same as Retatrutide?
GLP-3 commonly refers to the triple-agonist activity profile; Retatrutide (LY3437943) is the specific compound widely studied for that profile.
Do different vial sizes have different purity?
No. All sizes (10mg, 15mg, 20mg, 30mg) should meet the same ≥99% purity spec when sourced from a verified supplier. Always confirm the batch COA.
Which size should I buy for a new line of experiments?
Most labs start with 10mg or 15mg for pilot work. For ongoing projects, 20mg is a common standard; 30mg delivers the best cost-per-mg when usage is sustained.
Is it legal to buy Retatrutide in the U.S. for research?
Yes—for bona fide laboratory research. Products are sold as Research Use Only and are not for human consumption.
How should I store Retatrutide vials?
Follow cold, dry, low-light practices and minimize temperature cycling. See our storage guide for details.
