I've been hearing some very interesting anecdotal evidence from a few top level national competitors as well as some pros that I talk with regularly and it seems anamorelin is showing some TREMENDOUS in field results. There isn't much research on it but I will post some below. Does anyone else have experience with anamorelin? Does any have any anecdotal or research based knowledge to add to help us all become more educated on the subject?
Pharmacodynamic hormonal effects of anamorelin, a novel oral ghrelin mimetic and growth hormone secretagogue in healthy volunteers.
OBJECTIVE:
Activation of ghrelin receptors stimulates GH secretion and appetite, increasing lean body mass and body weight. However, clinical use of ghrelin is limited because it has a short half-life and must be administered parenterally. Anamorelin is a novel, orally active, non-peptidic ghrelin mimetic and growth hormone secretagogue. Our objective was to evaluate its hormonal effects in healthy subjects.
DESIGN:
A double-blind, randomized, placebo-controlled study evaluated the short-term effects of anamorelin on GH, insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein 3 (IGFBP-3), prolactin, ACTH, LH, FSH, TSH, cortisol, insulin and glucose. Normal healthy volunteers (n=32) recruited from the general population were administered escalating doses of anamorelin (25, 50, and 75 mg daily) vs. placebo.
RESULTS:
Anamorelin significantly increased GH levels at all doses (p<or=0.01). Effects on the somatotropic axis were maintained, as evidenced by sustained increases in IGF-1 and IGFBP-3 compared to placebo following 5-6 days of treatment. Negligible effects on other anterior pituitary hormone profiles and on fasting glucose were noted and all mean hormone levels remained within normal range. Some degree of insulin resistance as assessed by HOMA-IR was evident after treatment with 75 mg dose but not with the 25 or the 50 mg doses. Significant dose-related increases in body weight were recorded. Changes in body weight directly correlated with changes in IGF-1 levels. Anamorelin was well tolerated.
CONCLUSIONS:
Anamorelin increases GH, IGF-1, IGFBP-3 and body weight with good tolerability and selectivity, without affecting other anterior pituitary axes or fasting glucose levels.

Therapeutic potential of anamorelin, a novel, oral ghrelin mimetic, in patients with cancer-related cachexia: a multicenter, randomized, double-blind, crossover, pilot study.
Abstract
PURPOSE:
Cachexia in cancer adversely affects patients' perception of symptoms, well-being, and response to therapy, and shortens survival. Anamorelin, an oral mimetic of ghrelin, has been shown to increase body weight and anabolic hormone levels in healthy volunteers and is being investigated to treat cancer cachexia.
METHODS:
This multicenter, double-blind, placebo-controlled, crossover study evaluated the effects of anamorelin in 16 patients with different cancers and cachexia. Patients were randomly assigned to anamorelin 50 mg/day or placebo for 3 days. A 3- to 7-day washout period followed and then treatments were switched. Assessments included body weight, appetite, food intake, growth hormone (GH) levels, patient-reported symptom assessments (e.g., the Anderson Symptom Assessment Scale [ASAS] and also an inclusion criterion), and safety.
RESULTS:
Anamorelin significantly increased body weight compared with placebo (0.77 kg vs. -0.33 kg). Food intake increased compared with placebo, but not significantly. GH significantly increased at all time points (0.5-4 h postdose). Insulin-like growth factor-1 (IGF-1) significantly increased by 54.09 ng/mL with anamorelin treatment compared with -3.56 ng/mL for placebo; significant changes in insulin-like growth factor-binding protein 3 (IGFBP-3) were 0.75 μg/mL vs. -0.19 μg/mL, respectively. Patient-reported symptoms, including appetite as measured by ASAS, significantly improved with anamorelin (8.1 vs. 1.0 for placebo). Adverse events (AEs) in four patients were possibly or probably related to anamorelin: hyperglycemia (two patients), nausea (one patient), and dizziness (one patient). Most AEs were mild; no patients withdrew due to AEs.
CONCLUSIONS:
Anamorelin showed significant metabolic, clinical, and patient-rated effects in cancer cachexia. Further studies are warranted.
