Because that's what all sources started selling at first. The trend was 250mcg then ppl started hyperdosing it following the studies and then the 20mg came out.Ok Bro, so why Yura sell 100x250mcg tabs??
Peptides website around still sell 250mcg only for big money xD
No one knew the dosages for slupp, even now we don't really know but surely probably not 250mcg.
You can try 2/3mg day and see if you can feel something
