Peptide GRF (1-29) (Sermorelin, Sermoreline) and its use in bodybuilding
GRF (1-29) is a peptide hormone of the GHRH class, which increases the synthesis of growth hormone in the body. This peptide, most often, is sold under the trademark Sermorelin (Sermorelin).
Features of Sermorelin GRF (1-29)
The main feature of GRF (1-29) is a very fast half-life in the body, which is only a few minutes (5-10). For this reason, the classical forms of GRF (1-29) provide a weak increase in the concentration of growth hormone and, accordingly, have low efficiency.
The exception is GRF (1-29) Mod - tetrasubstituted or modified GRF (1-29). Its feature is the additional 4 amino acids included in its composition and providing a half-life of about 30 minutes. This provides a longer lasting effect and significantly better stimulation of growth hormone production in the body.
GRF (1-29) and CJC-1295
Very often GRF (1-29) and CJC-1295 DAC confuse each other, however, having similarities in structure, they differ significantly in action. Thus, CJC-1295 DAC is a modified peptide of the GHRH type, which contains the amino acid lysine, which is bound to the molecule Drug Affinity Complex (DAC). This combination allows the CJC-1295 DAC to have a half-life of 1-2 weeks, which is much more convenient, since it allows injections only a couple of times a week (instead of 1-3 times a day).
Dosages and course GRF (1-29) Sermorelin (Sermorelin)
The optimal dosage of GRF (1-29) Mod is 100-200 μg, taken 1-3 times a day in the form of subcutaneous or intramuscular injections. The total duration of the course is 6-12 weeks.
The optimum is the combination of GRF (1-29) with the reception of peptides like GHRP in the following course:
Serrorelin GRF (1-29) - 100-200 mcg;
GHRP-6 or GHRP-2 - 100 μg;
Peptides must be dissolved in 1-2 ml of water and administered 1-3 times a day;
The optimal time of reception: 15 minutes before meals, immediately after training and before bedtime.
How to make a solution of GRF (1-29)?
Take the vial and cool it to room temperature;
Add the necessary amount of water for injection (the addition of water should be carried out by draining it along the wall of the bottle);
Stir the resulting composition (do not shake or shake, but use circular rotational movements);
The resulting composition can be stored in the refrigerator without freezing for 8-10 days (with the use of bacteriostatic water - up to 30 days).
Important! Tetra-substituted (modified) GRF (1-29) Mod is best dissolved only in bacteriostatic water.
