This is different batch, same quality
You are just a reseller
How can you possibly make such a claim and expect people to believe it
You don't have any magical powers that let you wave a crystal over the top and get the vial to tell you what's inside it.............or do you?
Saying things like "This is a different batch but it's just as good as the last batch" is probably the fastest way to tank yourself here
How about trying something like this:
When you receive a "batch" of hgh
1. Publish how many kits are available in that batch
2. Label each kit with a batch number, like kit # 20 of 200. 20/200
3. Publish photos of what the vials in that specific batch look like
4. Send it to testing. In the test sheet, include the batch # and which box number it came out of
5. Props on the triple variance and dimer testing. Keep doing that.
6. When a batch sells out, mark it as dead.
7. Next batch.
This was off the cuff. Others probably have better suggestions
