We've seen a significant uptick in orders for these over the last year, especially for the Retatrutide and Epithalon, and what most labs find is that the batch-to-batch consistency saves them form having to recalibrate protocols—it's not just about the >99% purity (which we verify by HPLC on every lot), it's that you get the same profile run after run, so your stay relaible.
Actually, the lyophilized powder comes sterile-filtered, which means you don't have to worry about additional filtration before reconstitution if you're working under a hood—just use bacteriostatic water or saline, and you'll typically get a clear solution within 30 seconds or so, though some peptides like Semax dissolve a bit faster than others.
3-5 business days is our usual lead time for most peptides in stock, but if you're ordering bulk quantities (50 vials or more), it can stretch to about two weeks—we usually have stock on the core compounds like Retatrutide and Epithalon, but teh less common ones might require a confirmation before we commit.
For buyers who aren't sure which peptide to start with, most go with the 10mg vials for initial screening because they're easier to handle during reconstitution than the larger sizes, but we also offer 5mg and 25mg depending on your batch needs—just note that the 25mg vials require a bit more care with dissolution to avoid clumping.
One detail you might not think to ask: the white powder can sometimes look slightly off-white under certain lighting, but that's normal for high-purity lyophilized matrial and doesn't indicate degradation—what it does is reflect trace moisture from the lyophilization process, which is within spec but noticeable if you're used to crystalline standdard.
It's not suited for long-term storage at room temperature—even though the dry powder is stable for a few weeks at ambient conditions, you really want to keep it at 2-8°C after reconstitution, and for dry state, a desiccator is fine but a freezer is better if you're holding it for more than 6 months.
We don't have a strict MOQ. You can order as little as a single vial to test, but bulk discounts kick in at 10 vials or more per peptide.
The COA is sent within 24 hours of your order confirmation. It includes the HPLC purity report, lot number, and sterility test results.
Yes, every batch of every peptide—Retatrutide, Epithalon, Semax, and the rest—is individually HPLC-verified at >99% purity. We don't mix or average results.
Keep the powder in a cool, dry place away from light, ideally at -20°C for long-term storage. After reconstitution, store it at 2-8°C and use within 7 days.
We can do custom labels with your lab's details or adjust vial fill amounts for bulk orders, but lead time adds about 5-7 business days. Just let us know the specs.
