Stano – XT New Lean Mass Prohormone


10X IGF EME is the STRONGEST Deer Antler product in America.


Yes you read that correctly, 1 capsule of 10x has more in it then 99% of all of our competitors have in their entire bottle!

10x IGF EXTREME contains a highly purified Deer Antler Velvet Extract.  Deer Antler Extract is commonly known to contain the following Growth Factors in high levels:

  • Insulin like Growth Factor I (IGF-1) and IGF-1 LR3
  • Insulin like Growth Factor II (IGF-2)
  • Transforming Growth Factor Alpha
  • TGF Beta (Transforming Growth Factor Beta)
  • Leutienizing hormone stimulant
  • Epidermal Growth Factor
  • Vascular Endothelial Growth Factor
  • Nerve Growth Factor
  • Neurotrophin Growth Factor 3
  • Fibroblast Growth Factor (3 types)
  • Interleukins Bone Morphogenetic Protein 4
  • Related growth co-factors
  • Plus several other GF’s in moderate to low levels


10x might appear to be expensive but when you compare, and do the math 10x is one of the most cost efficient products in the market place.  Since it is so strong you would have to often pay $10,000 to over $30,000 worth of our competitions products to equal one bottle of 10X IGF EXTREME.

When taking SOTO Supplements 10X IGF EXTREME you should read the instructions as dosage is by body weight.  If you start to experience mild headaches drink more water or reduce dosage by one capsule per day.


A History of SOTO Supplements

  • 2011:  Product officially launched to retail stores.
  • 2013:  Extraction process refined and herd husbandry changed to increase potency of extract.
  • Jan 2013 STARTED USING FINER MATERIAL WHICH INCREASED POTENCY OF THE PRODUCT.  Started using a finer material that was tested to increase absorption rate and increased the potency of the product.  This new material was in testing for 5 months before we decided to switch.
  • May 2013 CHANGED CAPSULE WEIGHT ON THE LABEL TO 450MG FROM 500MG.  NO CHANGE TO THE PRODUCT.  Historical weights in the last year and a half have always been a little below the stated 500mg.  This weight also changes per capsule and per batch due to normal deviations in manufacturing.  The label has been updated to read 450mg due to weights showing between 465mg and 480mg and SOTO Supplements wanted to make sure that its products were over the stated amounts instead of below.
  • 2014:  Label updated to new SOTO Black Label



1 review for THE GQ – LEAN MASS STACK

  1. 5 out of 5

    I am a 52 year old man who used 10X IGF extreme for two separate cycles. I have gained 10 lbs of muscle mass and have leaned out. Great product and can’t wait to use the Stano XT and 10X IGF stack for my next cycle. The owner Jessica is very helpful offering information on supplements that Soto offers. Superior customer service and a pleasure to work with.
