    Both are SARMs that were created by GTX for different purposes.
    It seems the target market for Ostarine is Andropause and the target for Andarine are Cancer Patients as it supposedly flys under the radar of cancer and does not stimulate its growth.

    Couple of links:

    Safe compared to what, a bowl of tapioca pudding??

    Not like research peptides are in ANY phase of FDA testing and we use those based on our own research info and anecdotal evidence.
    Same can be said about steroids, the way we use them here.

    Wait a bit and see if BabyBlu keeps posting while running S-4. As long as he does, thats enough for me

    Your right. Soon as I can afford it I would love to try it.

    I was thinking safe compared to superdrol haladrol pp, epistane etc. Maybe a stack? I still have some HD and PP left and epistane. For a future cycle.

    i saw the clinical profile on S-4 and was far from impressed....plus i make a point not to listen to the salesman when considering a purchase.

    i believe there is a future to SARMs, but i dont think S-4 is it...

    I agree. I did not see anything striking about S-4 on paper.

    I'd rather wait for SARMS that are not selective for the pituitary and hypothalamus than the prostate and such...

    On a scale of 1-11 so the effectiveness seems like a 7 out of 11.

    hmmm. effectiveness? what effect are you judging. Strength, Hypertrophy, Liver Values, HDL/LDL, etc? What are you comparing this to? Test, Deca, Tren, etc?
    Pretty general statement, and in itself has no real meaning.

    BTW, why "1-11"?!

    On a scale of 9 to -5, my confusion level is a 11 here

    Well I was thinking like strength, size compared to like superdrol, epistane. I know the sides are way better than something like superdrol hyperdrol etc no liver toxicity; no affect on the prostate no effect on breast tissue no effect on the heart and minimal effect on HPTA I know. I was thinking maybe stack with a low dose of epistane or low dose of superdrol.

    once my injury heals i will do a full two month cycle of S4 at 200mg/day

    i maybe running that with some peps but depends on timing.

    currently doing 3on 4 off using S4 (200mg/day),its a new way of pulsing, talked to some people that has done that with mdrol and such with no sides for months, where regular pulse fck people up.

    lets not debate about that pulse...just letting you know i will be logging soon after my tri's heal.

    so far on 'ON' days, i feel good psychologically, not much growth, just hardness i feel during 3days of on, wonder how others will do at higher dosage and longer duration?


    when i first heard of S4 i was let down that it still affected HPTA, but nontheless it sounds interesting so im taking it.

    i would love to try future SARM's that wont affect HPTA and only muscles....sweeet! i will be on something like that rest of my life.

    imagine females using these stuff with no androgenic sides, thats going to replace alot of chemicals in the future, anxillary and so on. **** it will replace everything for both men and women.

    Well I havent seen any conclusive research evidence that S-4 has a significant negative impact on the HPTA. In fact GTX claims that SARMS enhance libido. I know that my libido currently is about normal for me. Ejaculate amounts are not down. I think the thing that most people forget about the human studies done on S-4 is that the sample group were men in their 60s-80's I believe. So people look at the study and say that the amount of LBM increase after 3 months was only like 6 lbs. But I would wager that 500mg of test enth a week would not put on much more LBM on men in their 60-80s with NO exercise. Now of course test enth would probably put on a significant amt of water weight to men no matter their age but actual lbm (again in light of no exercise routine) would be minimal. So you have to put S-4 studies (like everything in this world) into the proper context.

    Im not making any projections on this stuff. Im just hopeful and also I did notice an increase in vascularity the last couple of days. Last night I noticed a 'new' vein in the lower palm of my hand, under my thumb. Odd.

    My chronological age is 24 my actual years but I am aging at at a slower rate so the doctor said Im around the age of 16. I think I said it correctly.

    Ahh... I see. If I may ask, what are you diagnosed with exactly? If that's too personal for the forum, I completely understand. Just wanted to know if you are biologically still in a pubertal phase as exhibited by your endogenous hormonal levels (test, IGF-1, etc).

    S-4 is an easier way of saying:

    S-3-(4-acetylamino-phenoxy)-2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-propionamide

    Here is another good full text writeup on S-4:

    Selective Androgen Receptor Modulator Treatment Improves Muscle Strength and Body Composition and Prevents Bone Loss in Orchidectomized Rats

    Abstract below:

    Selective Androgen Receptor Modulator Treatment Improves Muscle Strength and Body Composition and Prevents Bone Loss in Orchidectomized Rats


    The partial agonist activity of a selective androgen receptor modulator (SARM) in the prostate was demonstrated in orchidectomized rats. In the current study, we characterized the full agonist activity of S-3-(4-acetylamino-phenoxy)-2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-propionamide (a structurally related SARM referred to in other publications and hereafter as S-4) in skeletal muscle, bone, and pituitary of castrated male rats. Twelve weeks after castration, animals were treated with S-4 (3 or 10 mg/kg), dihydrotestosterone (DHT) (3 mg/kg), or vehicle for 8 wk. S-4 (3 and 10 mg/kg) restored soleus muscle mass and strength and levator ani muscle mass to that seen in intact animals. Similar changes were also observed in DHT-treated (3 mg/kg) animals. Compared with the anabolic effects observed in muscle, DHT (3 mg/kg) stimulated prostate and seminal vesicle weights moire than 2-fold greater than that observed in intact controls, whereas S-4 (3 mg/kg) returned these androgenic organs to only 16 and 17%, respectively, of the control levels. S-4 (3 and 10 mg/kg) and DHT (3 mg/kg) restored castration-induced loss in lean body mass. Furthermore, S-4 treatment caused a significantly larger increase in total body bone mineral density than DHT. S-4 (3 and 10 mg/kg) also demonstrated agonist activity in the pituitary and significantly decreased plasma LH and FSH levels in castrated animals in a dose-dependent manner. In summary, the strong anabolic effects of S-4 in skeletal muscle, bone, and pituitary were achieved with minimal pharmacologic effect in the prostate. The tissue-selective pharmacologic activity of SARMs provides obvious advantages over steroidal androgen therapy and demonstrates the promising therapeutic utility that this new class of drugs may hold.

    Ostarine and Andarine are both aryl propionamide analogs. From this writeup it seems that S-4 is a further altered version.

    http://molinterv.aspetjournals.org/c...nt/5/3/173.pdf

    When the idea of trifluoromethylation was utilized by our laboratory to discover novel aryl-propionamide AR agonists, we identified novel and important in vitro SARs for the AR-binding affinity and agonist activity (30, 31), including a para-nitro group in the A-ring, a trifluoromethyl group linked to the chiral carbon (R-isomer), a thio-ether linkage, and a halo or para-N-alkylamido group in the B-ring. When these compounds were tested in vivo, however, no pharmacologic
    activity was observed owing to their unfavorable pharmacokinetic properties (32). Further structural modification was made to overcome this problem by changing the thio-ether linkage to an ether bridge, which resulted in the successful discovery of the first member, S-4, of a new series of SARMs

    i just dont quite get it....the stuff appears to work just like nandrolone. it provides next to no androgenic support:

    (DHT (3 mg/kg) stimulated prostate and seminal vesicle weights moire than 2-fold greater than that observed in intact controls, whereas S-4 (3 mg/kg) returned these androgenic organs to only 16 and 17%

    so unless you want to stack it with T or DHT or proviron or masteron or something, you're not going to have much in the way of libido during a cycle...and obviously, all those steroids impact the prostate, so what's the point again?

    I'm not impressed with the studies on S-4 at all.

    The main selectivity (lack of actually)I care about there being would be non-selectivity for the HPTA...
    Thats where the gold would be for performance enhancement...

    hopefully the answer of suppression will be answered soon. I like the fact that it does appear to be "safer" than the orals I have access to (I can only use legally obtainable research items), non methyl, easy on prostate, etc. and the gains seem to be very lean, slow and maintainable, not a size monster obviously since no or low aromitization. But I do agree that non-suppressive would be great, but we will see. If it is not, I am hoping that recovery will be quick and easy.

    what question is there?? this product is highly suppressive, period.

    "...significantly decreased plasma LH and FSH levels in castrated animals in a dose-dependent manner."

    that's pretty much all there is to it. test + S-4 would be a fun cycle (as long as you kept the T dose high enough to keep your libido), but S-4 solo sounds like deca solo....fine for some, but not for most.

    You are right based on the studies, but we all know of times where animal studies did not cross over 100% into human use. And part of it may be my hope that it is not suppressive. Either way, we should be getting some real world results, I think at least one fellow is going to have blood work done and he will have been researching it at the dosage most others are using and for a decent amount of time, I think about 6 weeks. We as individuals sometimes differ a little as well, but his bloodwork should give us another bit of information about this compound. I do agree about the s-4 and something else, this is supposed to be 100% s anabolic as test prop, but only 33% as androgenic, again based on activity in animal studies, but the results so far on people; fat loss, lean body mass, slow or little actual weight gain, decent strength, speak of an anabolic substance. It is possible that this could be basically an effective non-methyl oral, so still good to use and possibly less harsh on the body. As I am always trying to keep my eye on safety, while at the same time taking some risks, this still sounds like a good product even with shutdown, as long as it doesnt turn out to be more suppressive than anything we currently have access to.
