What This Study Did, in Plain Language
What Was Tested
Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this controlled clinical trial publication.
The researchers investigated the responses of serum testosterone (T) and human growth hormone (hGH) concentrations to a bout of heavy resistive exercise and the responses of T, hGH, and insulin-like growth factor I (IGF-I) to a 16 wk progressive resistive training program in 13 men (60 +/- 4 yrs).
Fasting blood samples were drawn on 2 consecutive days prior to training and again on 2 consecutive days after the last day of exercise.
Who Took Part
The abstract describes 13 men taking part.
By PubMed's age tags, the people studied were middle-aged adults and older adults, men only.
How the Study Was Run
Body composition via hydrostatic weighing and muscle strength using a 3 repetition maximum (3RM) test on 6 variable resistance exercise machines were assessed before and after the training program.
What Was Measured
The researchers investigated the responses of serum testosterone (T) and human growth hormone (hGH) concentrations to a bout of heavy resistive exercise and the responses of T, hGH, and insulin-like growth factor I (IGF-I) to a 16 wk progressive resistive training program in 13 men (60 +/- 4 yrs).

What This Means in Plain Language
This is a controlled clinical trial of Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in 13 men.
With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.
The publication is from 1995 (International journal of sports medicine), a journal based in Germany.

Our Notes on the Compound
Exogenous HGH, sermorelin & older GHRPs (why they're passed over): Constant levels suppress the body's own GHRH, raise somatostatin and dull pituitary response.
