Double the dose, same quality

The 20mg is perfect for labs that go through a lot of this compound. Same exceptional purity as the 10mg. we've verified this on our own equipment. Great value.

Better per-mg cost

Saves us from ordering twice as often. Purity tested at 99.1% which is actually slightly better than the 10mg vial we got last time. Might just be batch variation but either way, excellent.

Marco E.✓ Verified

Love this size

the 20mg hits the sweet spot for our research. big enough to last us a few weeks but not so large that stability becomes a concern. and the quality... *chefs kiss*

Bianca F.✓ Verified

Great product, average shipping

Compound is excellent, no notes. Shipping took 6 days though, which feels long for a domestic vendor. Not a dealbreaker but something to be aware of.

Lab approved vendor

Went through formal vendor qualification at our university. NexPep passed on product quality, documentation, and consistency metrics. Official approved supplier now.

Simone H.✓ Verified

Yes yes yes

This is the one. Stop looking. NexPep reta is the real deal and the 20mg is the size to get.
