DELIVERY

I already paid, do i get confirmation of payment?

- Tracking info might not show or update instantly, give it some time, could be days. As long as you got a tracking number things are on the move and you will receive your parcel.

What is the difference between PostNL and Special Line?
- Special line minimizes customs risk. Its first sent from QSC to somewhere in your world region and from there its forwarded to your house. Special line is recommended, also takes a long time to show tracking updates.

I received my order but dont know what is each product!
- If you ordered domestic - email sigma@sigmachemical.com.cn writing SKU LIST on the email subject
- If you ordered international - email sigma@sigmachemical.com.cn asking for ID and providing your tracking number so they know who you are and what your order was.

How long does delivery take?
- This may vary but estimates are: US domestic less than a week, EU domestic about a week, International 2-4 weeks.
 
Oh I just disagree vehemently with the statement of esterified hormones can be taken orally. While technically correct to some extent, in practice it is not worthwhile.

It is possible I misconstrued what was said though I’m at work and just glancing

Are you referring to the older studies showing poor oral bioavailability of fat-soluble testosterone esters taken on an empty stomach (which was the "gold standard" to test oral bioavailability)?
There are more recent studies showing a high fat meal greatly increases oral bioavailability.
You still need to take a higher dose, but huge difference compared to taking on an empty stomach.

Peptides are a bit different but recent studies have shown we've been wrong about this, too.

Are we able to buy off the US domestic list as of now? 100iu GH kits specifically
If not , when is that possible ?
Yes, during the time that International is shut down for orders and shipping, you can still make US Domestic orders and US Domestic orders are still being shipped. QSC has literally made about (8) or (9) posts about this so please do not be lazy but just look for QSC's posts about this.

Fat or not there is no comparison to injection mg vs mg
