2 . Products quality and third party testing
Product quality is our priority, that's why we test all batches of raws produced in-house. Qingdao Sigma Chemical is a very large company, we have HPLC technology to test our raws, but
we do not offer reimbursement for third party testing for the following reasons:
- We have the cheapest products on the market, so that our customers are able to test their products themselves without financial impact, for example:
1 test kit e 65$
1 lab test 120$
---
Total = 185$
The vial of Test E will cost you 18.5$ while having performed your own test.
