In my experience, MK-677 is not worth it. I have used 4 brands, and my longest run was close to a year straight. Somatozine was definitely the best of the bunch- yielding some nice sleep benefits and I don’t recall feeling run down/lethargic on Somatozine. Other than that, I can’t really say that it benefited my physique or training all that much.
Back to MK-677 in general, it definitely gives me more of a beach ball look. Manipulating diet, sodium, potassium, adding a GDA, and even taking a baby aspirin daily (per suggestion in another thread), did absolutely nothing to change that.
I stopped using Somatozine this past spring when it was time to cut up a bit- which was successful. I went back on MK-677 from another board sponsor (not my first time from them) about 3-4 weeks ago in the midst of PCT and couldn’t figure out why I was feeling so lethargic and lifeless. My standard dose has always been 12.5 mg, and that’s exactly what I was doing this time around. Even for PCT, I just knew something wasn’t right...so I decided to cut out the MK-677. That was ~5 days ago and I feel so much better in every way.
Possibly it wasn’t so great of a batch, but given my general lack of enthusiasm for past MK-677 experiences, I think I am done forever either way. It’s the kind of thing that sounds much better on paper and studies than in reality....by a longshot. No to mention, the prices are grossly inflated and it can wreak havoc on metabolic health.
