How it works
1
Reconstitute your peptide vial by injecting the selected amount of bacteriostatic water slowly along the vial wall. Never shake — swirl gently.
2
The calculator gives you the exact syringe units to draw for your desired dose, based on the concentration achieved after reconstitution.
3
Store reconstituted peptide refrigerated at 2–8°C and use within 4 weeks. All products are for research purposes only.
Refund Policy
We stand behind every order — replacement or refund, no questions asked.
Purity below 98%
Every vial we ship is independently tested using HPLC and must meet a minimum of 98% purity. If your batch certificate shows purity below this threshold, contact us and we will issue a full replacement or refund immediately. We publish COA results for every batch so you can verify this yourself before and after purchase.
Fill volume under 90%
Each vial is filled to the declared volume before leaving our facility. If your vial arrives with a fill volume below 90% of what was stated — whether due to leakage, handling, or manufacturing error — we will send a full replacement at no cost, or issue a refund. Simply contact us with a photo of the vial and we will resolve it the same day.
Order seized in transit
In the event your package is seized or held by customs, we will issue a full replacement or complete refund at no additional cost. All we ask is that you notify us and share any documentation received from the relevant authority. We take full responsibility for transit outcomes.
How to claim

2
Send a brief description of the issue and any supporting evidence — photo of the vial, customs notice, or COA discrepancy.
3
We confirm and dispatch your replacement or process your refund within 24 hours.

About TK Labs
Research-grade peptides. No compromise on quality.

TK Labs Peptides was founded with one goal: to make pharmaceutical-standard research peptides accessible at fair prices. We partner directly with certified manufacturing facilities — cutting out the middlemen — and every batch undergoes independent third-party HPLC testing before it leaves the facility.

We publish the certificate of analysis for every batch so you can verify purity and quality yourself. No black-box sourcing. No marketing fluff. Just clean, verified peptides for serious research.
