We'd been running into inconsistent results with another suppiler's batch—HPLC showed purity dropping below 97% after three weeks, which basically wrecked our dose-response curve for that entire set of experiments.
This one's hitting 99% or better on the COA they sent over, and they run both mass spec and Janoshik verification on top of standdard HPLC, so we're not just relying on their word for it.
The lyophilized powder comes in sealed vials with desiccant, which helps a lot when you're pulling from teh same vial over a few days—moisture is the enemy here, and we've had issues with clumping before.
Storage isn't forgiving: -20°C in a dry environment is mandatory, and the shelf life is 24 months if you actually follow that, but we usually order in smaller amounts anyway since we don't want to risk degradation from repeated freeze-thaw cycles.
Avaliable in 2mg, 5mg, 10mg, 50mg, 100mg, or 500mg vials—we're going with the 10mg for now since it matches our typical aliquot size, but you'll want to confirm lead time because stock fluctuates on the higher quantities.
It's sterile filtered and soluble in both water and DMSO, so no extra prep headaches, but honestly this isn't something you'd use for anything beyond research—no in vivo work planned with this batch, and the GMP standard is more about consistency than clinical use.
We can work with small orders—typically 10 vials is our MOQ, but we can be flexible depending on your research needs. Just reach out with your required quantity and we'll see what we can do.
For in-stock Retatrutide, we usually ship within 3-5 business days. Custom batches or larger orders might take 10-14 days. We'll confirm the timeline when you place the order.
Yes, every batch comes with a COA that includes HPLC and MS test results. We also use Janoshik testing for extra quality verification, so you get full documentation on purity and identity.
Sure, we can customize vial sizes and packaging based on your request. Just let us know the specific amount per vial or the type of sealing you need, and we'll adjust the production accordingly.
Keep it at -20°C in a dry environment—moisture is the enemy. Our sealed vials come with desiccant, so store them unopened until use, and avoid repeated freeze-thaw cycles to preserve stability.
