Peptides CJC1295 Without DAC 2mg/vial

Description

CJC-1295 Without DAC is a synthetic, 29-amino acid peptide sequence (Tyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-NH2). It is a modified analog of the endogenous Growth Hormone-Releasing Hormone (GHRH), specifically comprising the biologically active fragment (GRF 1-29) with four key amino acid substitutions (D-Ala², Gln⁸, Ala¹⁵, Leu²⁷) designed to enhance its stability, receptor binding affinity, and resistance to enzymatic degradation (primarily by dipeptidyl peptidase IV - DPP-IV).

The critical distinction lies in the "Without DAC": Drug Affinity Complex (DAC) is a large molecule added to some peptides (like standard CJC-1295) to bind strongly to serum albumin, drastically extending its half-life from minutes to over a week, leading to continuous, non-physiological GH elevation. CJC-1295 Without DAC lacks this complex. Its effects are potent but transient, specifically designed to mimic and amplify the body's natural, short-lived GH pulses.

What is CJC-1295 Without DAC?

CJC-1295 is a synthetic analogue of Growth Hormone-Releasing Hormone (GHRH), a key hypothalamic peptide responsible for stimulating the pituitary gland to secrete pulses of endogenous growth hormone. The "Without DAC" designation is critical and distinguishes it from its longer-acting counterpart.

DAC (Drug Affinity Complex) is a moiety that binds to albumin in the bloodstream, significantly extending the compound's half-life from mere minutes to over a week. CJC-1295 with DAC provides a constant, elevated baseline of GHRH, leading to a sustained but non-pulsatile release of GH. This contrasts sharply with the body's natural, rhythmic pattern of GH secretion, which occurs in sharp, powerful bursts, primarily during deep sleep and after exercise.

CJC-1295 without DAC is the pure GHRH analogue, devoid of the DAC attachment. It is often referred to by its research name, Mod GRF 1-29, indicating it is a modified fragment of GHRH (amino acids 1-29) with enhanced stability and potency. Its primary action is to potently mimic the body's own GHRH, safely and effectively triggering these natural, pulsatile releases of growth hormone without disrupting the body's delicate feedback loops.

Features of CJC-1295 Without DAC

1.Growth Hormone Release Stimulation
The primary feature of CJC-1295 Without DAC is its ability to stimulate the release of endogenous growth hormone (GH) from the pituitary gland. Growth hormone is crucial for tissue growth, repair, fat metabolism, and overall health.

2.Non-Peptide Modifications
Unlike many other peptides that require frequent administration, CJC-1295 Without DAC has a structure designed to be more flexible with dosing, without the extended half-life seen in its DAC-modified counterpart.

3.Shorter Half-Life
CJC-1295 Without DAC has a significantly shorter half-life compared to its DAC version. This requires multiple injections to maintain elevated growth hormone levels, but allows for more precise control over GH release patterns.

4.No Drug Affinity Complex (DAC)
The absence of DAC means that CJC-1295 Without DAC is metabolized faster, leading to a quicker onset of action and shorter duration in the body. This results in a different dosing and cycling strategy compared to the DAC-modified form.

Half-Life and Pharmacokinetics

As established, the half-life of CJC-1295 without DAC is remarkably short, estimated to be around 30 minutes. This pharmacokinetic profile is the entire rationale behind its dosing strategy. It enters the system rapidly, creates a powerful, discrete signal to the pituitary to release a bolus of GH, and is cleared from the body quickly. This avoids the constant receptor stimulation that can lead to downregulation. The effects of the GH pulse it creates, however, are long-lasting, mediated through the sustained anabolic and metabolic actions of insulin-like growth factor 1 (IGF-1), which has a half-life of several hours.

Cycle Length: Patience for Quality Gains

●Typical Duration: 8 to 12 weeks is the standard cycle length.

●Rationale: While peptides generally have a lower risk profile, cycling allows the body to maintain sensitivity to endogenous GHRH and avoids potential long-term, unknown consequences. Longer cycles (e.g., 16 weeks) are sometimes used but should be approached cautiously.

●Time to Effect: Noticeable effects (improved sleep, recovery, skin) may appear within 2-4 weeks. Significant muscle gain and fat loss are cumulative and typically become more apparent in the latter half (weeks 6-12) of the cycle. Patience is key.

Post-Cycle Therapy (PCT): Generally Unnecessary, but Awareness is Key

●No Direct HPTA Suppression: CJC-1295 Without DAC works primarily on the GH/IGF-1 axis, not the Hypothalamic-Pituitary-Testicular Axis (HPTA) responsible for testosterone production. It does not suppress natural testosterone or estrogen production.

●No Receptor Desensitization: Due to its pulsatile nature mimicking physiology, significant downregulation of pituitary GHRH receptors is unlikely with standard cycles.

●Typical Approach: A formal PCT like SERMs (Clomid, Nolvadex) is not required after a cycle of CJC-1295 Without DAC alone or combined with Ipamorelin.

●What to Monitor:

○Natural GH Production: While unlikely to be suppressed, some opt for a period equal to the cycle length (e.g., 8-12 weeks off) to ensure full normalization, especially after longer cycles.

○IGF-1 Levels: Blood tests can confirm IGF-1 has returned to baseline.

○If Stacked with Suppressive Compounds: If CJC-1295 Without DAC was used alongside suppressive anabolic steroids or SARMs, a standard PCT for those compounds is absolutely necessary. The peptide itself does not change this requirement.

●Post-Cycle Strategy: Focus on maintaining training intensity, optimal nutrition (slightly reduced calories if in a deficit during cycle), and sleep to preserve gains. Some incorporate natural GH support (e.g., quality sleep, arginine, fasting) during the off-period.
