SPORT · STRENGTH & CONDITIONING
Strength coaches in South Africa are asked about peptides weekly. A client at a Johannesburg powerlifting gym has read about recovery peptides; a schoolboy rugby parent in Paarl wants to know if they are safe; a masters athlete wants to understand the GH axis. The coach who answers from the literature keeps credibility; the one who answers from a forum loses it.
This page gives a coach the literature. It covers hypertrophy and connective-tissue research, the GH/IGF-1 axis, and the anti-doping reality, and it names the compounds that genuinely appear in each. It is not a programme, and it is emphatically not a recommendation for anyone to take anything. The compounds are supplied for laboratory research only.
Muscle research relevant to a coach studies protein synthesis, satellite-cell activation and regeneration after mechanical damage. In peptides, that literature is mostly rodent: BPC-157 in muscle crush and tendon transection, TB-500 in myofibre regeneration after trauma, GH secretagogues in glucocorticoid-induced muscle loss. The GH/IGF-1 axis is the connecting thread, studied for collagen synthesis in tendon and for lean mass in animals and in GH-deficient adults.
Connective tissue is the second literature and arguably the more useful one for a coach, because tendon adapts slowly and injures often. Here the models are transected and collagenase-injured tendon, scored for fibre alignment and load to failure. The third literature is anti-doping: GH secretagogues and growth factors are prohibited at all times, detection windows are published, and a coach who understands this can protect an athlete from a career-ending mistake.
Research context only — what each compound has been studied for in published work, not what it does for anyone. Independently tested by Janoshik Analytical.
Studied for myoblast proliferation and faster functional recovery after mechanical muscle tears in rodents, and for tendon tensile recovery. It is the compound lifters ask about most, and its human data are close to nil.

View product and certificate →A selective GH secretagogue studied for pulsatile release without cortisol elevation; animal work on glucocorticoid-induced bone and muscle loss. Prohibited in sport at all times.
View product and certificate →GHRH analogue plus secretagogue, the research pairing for the full GH pulse. Human sleep-lab work on GHRH and slow-wave sleep is the part of this literature most relevant to recovery science.
View product and certificate →BPC-157 and TB-500 as a research set, the repair pairing that appears throughout tendon and muscle study design, with the stack page's note that no study has tested the two together.
View the research set →Coaches and gym-based research partners across Gauteng, the Western Cape and KwaZulu-Natal receive parcels in one to two business days from our Johannesburg hub with The Courier Guy, next day in most of Gauteng. Pay before noon on a weekday for same-day dispatch. A Courier Guy PUDO locker near the gym avoids front-desk sign-offs. Free shipping over R2,500; Janoshik certificate linked from every product page.

No. Nothing we supply is for human use, and the GH-axis and growth-factor classes are prohibited in sport at all times. We supply compounds for laboratory research only.
In rats, in transection models, with mechanical and histological endpoints. There is almost no human trial data, and our research pages grade it accordingly.
Because IGF-1 downstream of GH is studied for tendon collagen synthesis and lean mass, and because understanding it helps a coach explain to athletes why those classes are banned.
