    Stacking with 501516 for weight loss experiment. I”m really really pleased with results so far. Starting 161 lb @ 5’4″. Charting for 8 weeks and at the halfway point. Scale today: 149, so down 12 lbs in 4 wks! Subject also still running on treadmill 45min 3x wk. Also subject is eating clean, low carbs, high protein, etc, but not starving by any means!

    Subject has been using it for a cutting cycle. About 2 weeks so far, and working well. Seems less effective short term as GW which I used in my past experiments.

    I am actually super impressed by this s4 AND by sarmtech! I usually experiment with lgd, but lately with rad140, but igot s4 since the others were out. I didnt think it’d work as well being 1st generation Sarm! Vascularity, pumps, hardness ….. all way up after 4 weeks

    Fast awesome shipping, Great gains, Great price. Stacked rad140 (15mg), mk677 (15mg), LGD4033 (10mg) and MK2866 (15mg) and very pleased with experiment results so far! Only 2 weeks in and subject is breaking major records. Will start S4 in week 5 @ (25mg twice daily) and up rad140 dose to (30mg). Will definitely do a PCT along with GW501516.

    Subject had a fairly good response to S-4. The subject feels it is a good SARM, but appears to require a heavier dosage than others for a similar response. There was a slight increase in vascularity. Stacking with Cardarine has produced good results in holding muscle and decreasing body fat. -2.5% fat while holding steady at 35-36% muscle. Alone, S-4 might be more effective at a higher dosage than currently administered to the subject, 1 AM, 1 PM.
    Service & shipping from SARMTECH was on point. Requested items arrived very quick, and backorder status was communicated and filled/shipped as notified. Very satisfied with product, SARMTECH gets 5 stars.

  14. Austin F. (verified owner)

    Been testing this product for only 3 weeks, halfway through the first cycle with this product. Subject notices considerable gains in vascularity, veins popping out in places never before seen. No noticable weight loss so far, but I have noticed a considerable gain in muscle possibly partly due to sarmtech LGD, besides that I have noticed a V shaped taper developing to the body. Excited to finish out the rest of the cycle. Sarmtech as a company has so far been perfect in every way, I wouldn’t trust my sarm needs to anyone but them!

    Price per mg can’t be beat! Fast shipping too! Now for the product itself, first time trying out s4 and I’m loving what I’m seeing. Loss of some bf and some muscle hardness. Seeing some new cuts too. I’m sure this stacked with Ostarine and some Cardarine would make some more pronounced results.

    Subject has been on long enough to notice a significant vascular change especially in the arms and neck. It’s great. The vision sides that come with s4 are annoying but at least you know they’re legit and subject has them. Good product.
