SPORT · PHYSIQUE
Physique coaches in South Africa are the most peptide-literate audience in sport and the most exposed to bad information. The forums that shaped the culture mix real papers with invented protocols, and a prep coach who wants to understand the actual literature has to pull the two apart alone.
This page does the pulling. It covers the GH/IGF-1 axis research, the body-composition trials in the incretin and GHRH-analogue literatures, the skin and tanning research in context, and the recovery models. It states what each study measured and how strong it is. It is not a prep plan, contains no dosing, and the compounds are supplied for laboratory research only. Tested federations prohibit most of these classes.
The GH-axis literature is the physique coach's native ground. GHRH(1-29) and its analogues raised GH dose-dependently in healthy men in 1980s endocrinology studies; secretagogues such as ipamorelin were characterised for selective, pulsatile GH release without cortisol; GHRH administration increased slow-wave sleep in human sleep labs; and GHRH-analogue trials in older adults tracked body composition. The findings are real, mostly small, and from populations that are not competitive bodybuilders.
Body-composition trials with hard numbers come from the incretin literature: tirzepatide's SURMOUNT programme and retatrutide's phase 2 and 3 trials report mean weight change with DXA sub-studies on lean versus fat mass. Those compounds have their own research pages. The skin literature adds copper peptides with human collagen trials and glutathione with pigmentation trials; the melanocortin tanning research is covered on its own pages. Recovery models are the rodent tendon and muscle work.
Research context only — what each compound has been studied for in published work, not what it does for anyone. Independently tested by Janoshik Analytical.
The selective ghrelin-receptor agonist characterised for pulsatile GH release without a cortisol rise. Animal work reports it counteracted glucocorticoid-induced bone and muscle loss. Prohibited in tested sport.
View product and certificate →GHRH analogue plus secretagogue, the research pairing for the full GH pulse. GHRH(1-29) raised GH in normal men and increased slow-wave sleep in sleep-lab studies.
View product and certificate →The mitochondrial peptide studied in mice for AMPK activation, fatty-acid oxidation and muscle glucose uptake. The compound in the physique literature with the clearest metabolic mechanism and the thinnest human data.
View product and certificate →Copper peptide with human trials on collagen I, elastin and dermal thickness. Enters physique reading through the stage-skin conversation; the trials were not on competitors.

View the research set →Physique coaching is concentrated in Johannesburg, Pretoria, Cape Town and Durban, all inside The Courier Guy's one-to-two business-day lane from our Johannesburg hub, with Gauteng usually next day. Weekday orders paid before noon dispatch the same afternoon in discreet, tracked packaging. A PUDO locker near the gym is selectable at checkout. Multi-vial research orders usually clear the R2,500 free-shipping line; Janoshik certificates are linked per product.

No, anywhere on the site. We describe the literature and supply compounds for laboratory research only.
Listed on the site with their own research pages describing the trial data. They are mentioned here only because their DXA sub-studies are part of the body-composition literature.
Yes. Anti-doping laboratories publish detection methods for secretagogues and GHRH analogues, and they are prohibited at all times in tested sport.
Compound identity and HPLC purity on an independent Janoshik Analytical report. Unpublished certificates are available on request.
