GenX Peptides

PEG MGF

PEG-MGF (Pegylated Mechano Growth Factor) is a synthetic, long-acting version of MGF—a splice variant of IGF-1—engineered to help with muscle growth, repair, and recovery, especially after physical stress or injury.

MGF (Mechano Growth Factor) is a natural variant of IGF-1, expressed locally in muscle tissue in response to mechanical overload (e.g., intense exercise)
PEG-MGF is chemically modified by attaching a PEG (polyethylene glycol) chain, which:
Extends its half-life from minutes to days
Allows for systemic use (instead of just local effects)

200–400 mcg, 2–3 times per week.
Usually subcutaneous or intramuscular injection
Best timing: post-workout, ideally into trained muscle (but systemic effect is fine due to PEGylation)
Cycle length: 4–6 weeks

CJC DAC-1295

CJC-1295 with DAC is a long-acting growth hormone-releasing hormone (GHRH) analog designed to stimulate natural growth hormone (GH) release over an extended period—up to a week per dose.

DAC = Drug Affinity Complex, which significantly extends the peptide’s half-life to ~5–8 days.
Unlike CJC-1295 without DAC (Mod GRF 1-29), which mimics pulsatile GH release, CJC with DAC causes sustained GH elevation
It binds to albumin in the blood, allowing for weekly or twice-weekly dosing

1–2 mg per injection, 1–2x per week
Subcutaneous or intramuscular injection
Because of its long action, daily dosing is not required
Can be used alone or with occasional GHRP/IPAM dosing to amplify pulses

IGF-1 DES

IGF-1 DES (1-3) is a modified version of the Insulin-like Growth Factor 1 (IGF-1) protein, designed to be more potent and have different biological effects. Here’s a breakdown:

GF-1 DES (1-3) is a truncated version of IGF-1, where the first three amino acids of the full IGF-1 peptide are removed
The “DES” stands for “des(1-3)”—indicating the deletion.
This modification prevents it from binding to IGF-binding proteins (IGFBPs), which normally regulate IGF-1 activity
As a result, IGF-1 DES is up to 10x more potent than regular IGF-1 in stimulating muscle growth and cellular repair.

Half-life: Much shorter than regular IGF-1 (minutes vs. hours), making its effects more localized
Function: Promotes muscle hyperplasia (increase in number of muscle cells), not just hypertrophy (growth of existing cells)
Usage: Commonly researched for muscle repair, neuroprotection, and tissue regeneration. Often studied in bodybuilding contexts, although it’s not approved for such use.

CJC+GHRP-6

CJC-1295 + GHRP-6 is a well-known peptide combination used in research for stimulating growth hormone (GH) release. When used together, they have a synergistic effect—amplifying GH pulses far more than either alone.

A GHRH (Growth Hormone Releasing Hormone) analog.
Stimulates the pituitary to release GH of two types:
CJC-1295 DAC (long half-life: 1–2 weeks)
CJC-1295 w/o DAC aka Mod GRF 1-29 (shorter half-life: ~30 minutes)
Mod GRF 1-29 is commonly paired with GHRPs for pulsed GH release.
2. GHRP-6 (Growth Hormone Releasing Peptide-6)
A Ghrelin mimetic that also stimulates GH release but via a different receptor.
Promotes hunger and can raise cortisol and prolactin slightly.
Effective in synergy with CJC-1295.

HGH

Somatropin is the pharmaceutical (recombinant) form of human growth hormone (HGH)—a 191-amino acid protein identical to the GH your pituitary gland naturally produces.

A synthetic HGH made using recombinant DNA technology
Bio-identical to endogenous GH
Used medically to treat GH deficiency, growth failure, muscle wasting (e.g., in HIV/AIDS), and sometimes anti-aging or performance-enhancing in non-medical contexts.

Stimulates IGF-1 production in the liver, which promotes
Muscle growth
Fat metabolism (lipolysis)
Cell regeneration
Bone density improvements
Recovery and healing

FRAG(10MG)

HGH Fragment 176-191 is a modified version of human growth hormone (HGH) that specifically targets fat loss without many of the effects associated with full-length HGH.

It is a synthetic peptide derived from the C-terminal end (amino acids 176 to 191) of the human growth hormone molecule.
This fragment represents only ~10% of the full 191-amino-acid HGH, but it retains the fat-burning properties
It does not cause the typical HGH side effects such as insulin resistance, water retention, or increased IGF-1 levels

Typical research dosing: 250–500 mcg per day, often split into 2 doses (morning + pre-bed).
Best administered subcutaneously on an empty stomach.
Often studied in cycles of 4–12 weeks.

FRAG+(20MG)

HGH Fragment 176-191 is a modified version of human growth hormone (HGH) that specifically targets fat loss without many of the effects associated with full-length HGH.

It is a synthetic peptide derived from the C-terminal end (amino acids 176 to 191) of the human growth hormone molecule.
This fragment represents only ~10% of the full 191-amino-acid HGH, but it retains the fat-burning properties
It does not cause the typical HGH side effects such as insulin resistance, water retention, or increased IGF-1 levels

Typical research dosing: 250–500 mcg per day, often split into 2 doses (morning + pre-bed).
Best administered subcutaneously on an empty stomach.
Often studied in cycles of 4–12 weeks.

GHRP-6

GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic peptide used in research to stimulate growth hormone (GH) release by mimicking ghrelin, the “hunger hormone.”

Mechanism of Action:
Binds to the ghrelin receptor (GHS-R) in the pituitary and hypothalamus
Stimulates a natural GH pulse
Can be combined with GHRH analogs like CJC-1295 (Mod GRF 1-29) for a synergistic GH release
Unique Characteristics:
Increases appetite—a lot. This is due to its ghrelin-mimicking action
Stimulates prolactin and cortisol slightly at higher doses
Very short half-life: ~30 minutes, so timing matters

Increased GH and IGF-1 levels
Promotes muscle growth, fat loss, improved sleep, recovery, and healing
May support joint repair and anti-aging effects

100–300 mcg per dose, 2–3x daily
Must be taken away from carbs and fats, which blunt GH release

GHRP-2

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic peptide in the GHRP family, similar to GHRP-6, designed to stimulate growth hormone (GH) release via the ghrelin receptor.

GHRP-2 binds to the GHS-R1a receptor, mimicking ghrelin, and triggers natural GH pulses
Works best when paired with a GHRH analog like Mod GRF 1-29 (CJC-1295 without DAC) for enhanced GH secretion.

Promotes:
Muscle growth
Improved recovery and sleep
Joint and tissue healing
Slight hunger stimulation (less than GHRP-6)

100–300 mcg per injection, 2–3x daily
Avoid carbs/fats for 30–60 mins before/after to maximize GH pulse

IGF-1 LR3

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic, extended version of IGF-1 designed for greater potency and duration in the body. It is commonly used in research focused on muscle growth, cell regeneration, and anti-aging.

IGF-1 stands for Insulin-like Growth Factor 1, a hormone similar in structure to insulin
It is the primary mediator of growth hormone’s anabolic effects, promoting muscle repair, cell growth, and fat metabolism
LR3 means: Long: It has an extended half-life (~20–30 hours vs. ~30 minutes for native IGF-1)
R3: The third amino acid is replaced with arginine, which prevents binding to IGF-binding proteins (IGFBPs) that normally inhibit its activity
This makes IGF-1 LR3 ~2–3 times more potent than native IGF-1

20–100 mcg/day, often in a single daily subcutaneous injection● Sometimes site-injected into muscles post-workout to localize effects (though systemic effects still dominate)
Cycle length: 4–6 weeks is common in research settings
