[Influence of twice-daily injections of GRF 1-29 on production, feed intake and nutritional status of lactating goats].
Sauvant. D D; Kann. G G; Hervieu. J J; Disenhaus. C C
Key Findings
- Twice‑daily GRF‑1‑29 injections significantly raised milk output in lactating goats.
- Voluntary feed intake showed a modest increase after peptide administration.
- Despite higher production, the goats experienced a negative energy balance (they burned more energy than they took in).
Practical Outcomes
- For biohackers, this study suggests that GRF‑1‑29 can boost anabolic outputs (like milk in goats), hinting it might enhance growth‑related pathways in humans. However, the data come from a specific animal model, the dosage details are missing, and the negative energy balance warns of possible metabolic strain. Use this as a very preliminary clue, not a ready‑to‑apply protocol.
Summary
Giving goats twice‑daily shots of the peptide GRF‑1‑29 made them produce more milk. The goats ate a little more on their own, but the extra milk meant they ended up with a worse energy balance overall.
Abstract
Daily injections of GRF 1-29 significantly increased milk production of goats. Effects of injections were slightly positive on voluntary intake and negative on energy balance.
