We are currently offering Semaglutide for sale within the EU and UK.

Monthly $100 peptide giveaway​

We are giving away $100 worth of peptides, with free shipping, in a random draw that will take place at the end of each month.

If you’ve entered previously, you’ll still need to enter again for this month - but I have your info this time, so I’ll just need a quick email.

For new entrants, all you need to do to enter is indicate in an email to us (not a PM) that you’re entering. Also state whether you’d like to be kept up to date with our sales and contests. I’ll need your Reddit and/or SST username also, so that I can announce the winner. All information will be kept strictly confidential.

(We do not spam, and will respect whatever choice you make - if you don’t state either way, we’ll take it as a “no”.)

Send all entries to [email protected], not to our regular email address. All order emails should continue going to our regular address.


I get a lot of questions from folks new to peptides, so if you’re one of them, here’s a few links that should help with your research (not necessarily in order of usefulness):

Q: Do the dry peptides need to be stored in the fridge/freezer?
A: Our manufacturer informed us that: “For the activity, there would be no noticeable effect for 1-2 weeks at 25-30°C. We have done some testing at 25°C and 60% humidity (accelerated testing) for IGFLR3 and no effect on activity was seen, even after 12 months. In addition, peptides are shorter molecules than the proteins so they are less prone to degradation and denaturation so the data would be similar.” In other words, the unreconstituted vials will be fine at room temperature, in a dry environment. Also read this post: https://thinksteroids.com/community...-for-hgh-and-peptides.134393995/#post-2247090 - that’s 0.2-2% degradation after one year for a complex protein (HGH).

Q: Sometimes when I pull the needle out of the pep vial a bunch of solution squirts out. Am I doing something wrong or is this normal?
A: It’s normal, but you can avoid it by equalizing the pressure in the vial with the outside. Pull the plunger out of a syringe and stick the needle in there, you should hear a small “whoosh” if the pressure gradient was high. This is best done immediately after reconstitution, but can be done at any time.
Also, if you’re drawing just from that vial, you can push in an amount of air equal to what you’re going to withdraw so that the pressure stays the same.
