- 1x TZ2 20mg
- 1x Bacteriostatic Water 3ml
For laboratory and research use only. Not for human consumption. Not a medicine or supplement.
Why Choose the TZ2 20mg Starter Kit?
This kit is designed for researchers who want to begin working with TZ2 at a higher 20mg dose without placing two separate orders. Everything needed to prepare a working TZ2 solution arrives together in one shipment, from the same verified batch.
Reconstitution and Storage
Lyophilised TZ2 should be reconstituted with the included bacteriostatic water immediately before use, then stored refrigerated. Unopened vials should be kept in a cool, dark place until required. For step-by-step mixing instructions, see our TZ2 Research Guide.
Frequently Asked Questions
What does this starter kit include? One 20mg vial of TZ2 and one 3ml vial of bacteriostatic water, enough to reconstitute the full vial.
How is this different from the 10mg starter kit? It contains a 20mg vial of TZ2 instead of 10mg, suited to researchers running protocols that call for a higher total dose per vial.
Is TZ2 tested for purity? Yes, batch Certificates of Analysis are available on request. See our Certificates of Analysis page.
Who This Kit Is For
The Starter Kit TZ2 20mg is built for researchers who need a higher per-vial TZ2 dose and want a single, straightforward order rather than sourcing compound and reconstitution water from separate listings. It removes the guesswork of matching vial sizes to water volumes, since both arrive together, from the same verified batch, ready to prepare on arrival.
What’s Included in Detail
Each Starter Kit TZ2 20mg contains one 20mg vial of lyophilised TZ2 and one 3ml vial of bacteriostatic water, sized specifically to reconstitute the full 20mg vial without leftover water going to waste. Both items ship together in the same discreet, temperature-appropriate packaging as our standard orders.
Storage and Shelf Life
Before reconstitution, keep the TZ2 vial in a cool, dark place away from direct light and heat. Bacteriostatic water should also be stored at room temperature until use. Once reconstituted, the solution should be kept refrigerated and used within the timeframe outlined in our reconstitution guide to preserve stability.
Frequently Asked Questions
What does this starter kit include? One 20mg vial of TZ2 and one 3ml vial of bacteriostatic water, enough to reconstitute the full vial.
How is this different from the 10mg starter kit? It contains a 20mg vial of TZ2 instead of 10mg, suited to researchers running protocols that call for a higher total dose per vial.
How long does the reconstituted solution remain stable? Once mixed, store refrigerated and refer to our reconstitution guide for recommended usage windows.
Is TZ2 tested for purity? Yes, batch Certificates of Analysis are available on request. See our Certificates of Analysis page.
Can I order additional bacteriostatic water separately? Yes, additional water vials are available individually in our Lab Essentials category if needed for future batches.
Handling and Documentation Best Practice
Every Starter Kit TZ2 20mg is dispatched with a matching Certificate of Analysis so you can verify purity and identity before use. We recommend logging the batch number printed on each vial alongside the date of receipt and the date of reconstitution, as this makes it straightforward to cross-reference results against a specific batch later. Keep vials in their original packaging until first use to protect against light exposure, and always inspect the lyophilised powder for discolouration or clumping before reconstituting.
Why Researchers Choose This Kit
The Starter Kit TZ2 20mg bundles everything needed to begin working with TZ2 in one order, removing the need to source bacteriostatic water, syringes and vial adapters separately. This is particularly useful for laboratories running time-sensitive protocols, where waiting on a second delivery for missing accessories can delay a study. Every component in the kit is sourced and quality-checked to the same standard as our standalone research compounds.
