Ibutamoren (MK-677): the oral secretagogue with a two-year human trialSecretagogues

Ibutamoren (MK-677): the oral secretagogue with a two-year human trial

Most compounds in this catalog have no human data at all. This one has three randomised trials: a pulse study from 1996, an obesity study from 1998, and a two-year trial in 65 older adults that added fat-free mass without moving visceral fat. The numbers, exactly as published.

Liver support pens: reading the label against the literatureMetabolic

Liver support pens: reading the label against the literature

Two multi-ingredient liver pens, opened up component by component. Silymarin has a Cochrane review that reads against it, NAC has a poisoning antidote trial that does not transfer, and the finished blends have no trial at all.

BPC-157 in tendon research: what the rat studies actually show

Tendon models are the core of the BPC-157 animal literature, and a 2025 systematic review put the field's ratio at 35 preclinical studies to 1 clinical study. This page stays inside that ratio.

HCG and enclomiphene: what the fertility trials actually studiedHormonal

HCG and enclomiphene: what the fertility trials actually studied

Two compounds, four published studies, and a hard boundary: the literature describes what was measured in enrolled patients — intratesticular testosterone, sperm counts, pregnancies — not a protocol for anyone else. This article stays on the published side of that line.

HGH vs peptides: somatropin and the secretagogues, compared on the evidence

One is the hormone itself, approved since the 1980s for defined deficiency states. The others ask the pituitary to release more of it — and have one small trial, one PK study, or a single approval between them. The comparison searchers want has never actually been run.

Melanotan 2: three small trials, no approval — and the relative that got one

The entire human literature on Melanotan 2 is three trials in 23 men, run by one Arizona group in the 1990s. Nothing followed for tanning. Its chemical relative bremelanotide became an approved medicine — for one narrow indication that has nothing to do with tanning.

SARMs part 2: the one with trials, and the four with none

Part 1 covered the compounds with phase 2 and phase 3 programmes. The five left — ibutamoren, stenabolic, andarine, S-23, YK-11 — split into one with three real human trials and an ugly safety footnote, and four with no human efficacy data at all. Two of the five are not even SARMs.

This is one of the very few compounds on the repair shelf with real randomised human data — four published trials, including a 64-subject phase 2b. Read them closely and the nerve-regeneration endpoint separates from placebo while the pain endpoint mostly does not.

One of these three has been given to 3,080 humans — and the trial was stopped for futility. The other two have never been given to a human at all. All three are sold on the same phrase, and the phrase comes from one mouse treadmill experiment in 2008.

DSIP: named after an effect that later human work could not reproduce

Isolated from rabbit blood in 1977 and named for the EEG rhythm it enhanced. Four small human insomnia studies produced weak or null results, a 2009 anaesthesia study found it reduced delta rhythm, and no gene or receptor has ever been identified.

HGH Fragment 176-191 and AOD9604: a well-built mouse story with a missing human chapter

The idea was elegant — take growth hormone's fat-metabolism domain and leave the growth and insulin effects behind. It worked in obese mice, repeatedly. PubMed indexes 23 papers mentioning AOD9604 and not one randomised human trial.

Recombinant IGF-1 is an approved drug with a registry behind it. The LR3 analogue is a cell-culture reagent. PEG MGF has no administration study at all — the human MGF papers measure a gene switching on, not a peptide going in.

KPV: three amino acids off the end of α-MSH, and where its evidence actually sits

The mechanism is unusually well worked out — KPV enters cells through PepT1, a transporter that is upregulated exactly where gut inflammation is. Every efficacy result is a mouse or a cell line, and the colitis work was oral, not injected.
