Compound profileCND
CJC-1295 without DAC
What it is Usually a market name for modified GRF(1-29), a short-acting GHRH analogue.
Purpose & how it works Usually sold as modified GRF(1-29), this ingredient is intended to mimic a growth-hormone-releasing signal from the brain to the pituitary. The goal is to encourage the body to release its own growth hormone, which can influence downstream IGF-1. Without DAC refers to the absence of the long-acting albumin-binding modification. Shorter exposure is part of the selling story, but a product name alone does not confirm the exact sequence.
Gym & peptide talk / claims Gym users talk about deeper sleep, better recovery, staying leaner and maintaining muscle during a cut, often in conversations about an ipamorelin pairing. Fans describe it as supporting natural GH pulses. That language does not mean hormone levels stay normal or that muscle gains are assured.
Compound profileCD
CJC-1295 with DAC
What it is A GHRH analogue with a drug-affinity complex that prolongs exposure through albumin binding.
Purpose & how it works The DAC modification allows the peptide to bind albumin and remain active longer than a short-acting GHRH analogue. Its purpose is prolonged stimulation of growth-hormone signaling and downstream IGF-1. The key distinction is duration of exposure, not that it builds muscle through a separate anabolic pathway. Hormonal responses can persist, so this form should not be described as interchangeable with no-DAC products.
Gym & peptide talk / claims The enthusiast pitch is sustained GH support for recovery, sleep and body composition, with the longer action seen as convenient. Some users associate it with a fuller physique. Fullness can include fluid retention and is not automatically newly built muscle.
Compound profileCP10
CJC-1295 without DAC + IPA
What it is The list specifies 5 mg of no-DAC CJC plus 5 mg of ipamorelin.
Purpose & how it works The supplier lists 5 mg of each ingredient. The concept is to stimulate GH release through two different inputs: a GHRH-like signal from the CJC component and ghrelin-receptor signaling from ipamorelin. Fans describe the combination as encouraging a stronger GH response than either input alone. The intended downstream goals are recovery and body composition, but that hormonal rationale does not demonstrate those outcomes for this exact mixture.
Gym & peptide talk / claims This is a familiar gym-community sleep-and-recovery pairing. People discuss feeling more rested, bouncing back between sessions, holding strength while dieting and a tighter-looking waist. Reports are mixed: some describe better sleep, others more wakefulness or little visible change.
Compound profileIP
Ipamorelin
What it is A synthetic pentapeptide growth-hormone secretagogue acting through the ghrelin receptor.
Purpose & how it works Ipamorelin is designed to activate the ghrelin receptor and trigger GH release from the pituitary. It is promoted as relatively selective for GH compared with some older secretagogues. The proposed practical benefits flow from that GH/IGF pathway: recovery, body composition and sleep-related goals. Relative selectivity is a pharmacology description, not proof that it has no other hormonal effects or that a healthy adult will gain muscle.
Gym & peptide talk / claims Fans often describe it as the gentler GH peptide, with less intense hunger than GHRP-6, and discuss deeper sleep or less soreness. Much of the chatter involves combinations, so an apparent benefit cannot necessarily be attributed to ipamorelin alone.
Compound profileG25 / G210
GHRP-2
What it is A synthetic growth-hormone-releasing peptide in the ghrelin-receptor family.
Purpose & how it works GHRP-2 stimulates the ghrelin-receptor system to promote GH release. It belongs to an older family of secretagogues used to explore endocrine responses. The intended gym-related purpose is more GH signaling to support recovery and anabolic goals; appetite effects are also discussed. It is not selective for muscle growth, and human endocrine work shows that other hormones can change alongside GH.
Gym & peptide talk / claims The bodybuilding pitch is a strong GH pulse, better recovery and support for adding size. It is compared with GHRP-6 for hunger and with ipamorelin for side-effect selectivity. A stronger measurable hormone response does not establish a better physique result.
Compound profileG65 / G610
GHRP-6
What it is A synthetic ghrelin-receptor agonist and growth-hormone secretagogue.
Purpose & how it works GHRP-6 activates ghrelin-receptor signaling connected with both GH release and feeding behavior. This gives it two separate purposes in enthusiast discussion: stimulating the GH axis and making eating easier for someone who struggles to consume enough food. Increased appetite is not the same as improved nutrient partitioning. If calorie intake rises, the resulting weight gain can include fat as well as lean tissue.
Gym & peptide talk / claims The familiar gym label is the hungry one. Bulking discussions emphasize eating more, getting through large meals and recovering from hard sessions. That appetite-focused reputation makes it conceptually different from a GLP-1 cutting drug, even though both are called peptides.
Compound profileHX5
Hexarelin
What it is A synthetic GH-releasing peptide related to GHRP-6.
Purpose & how it works Hexarelin is another synthetic ghrelin-receptor-family secretagogue intended to produce a GH response. It has also attracted experimental interest in cardiovascular signaling, but that does not establish heart protection in gym users. Its purpose in performance circles is to amplify hormone-related recovery and growth signaling. It can affect prolactin, ACTH and cortisol as well as GH, which complicates simple claims about strength or recovery.
Gym & peptide talk / claims Enthusiast comparisons present it as a potent GH releaser for recovery, strength and size. The intensity of that reputation should not be read as a ranking of effectiveness or safety. Changes in hormonal markers are easier to demonstrate than durable gains in muscle.
Compound profileSMO
Sermorelin
What it is A 29-amino-acid GHRH fragment that stimulates pituitary GH secretion.
Purpose & how it works Sermorelin reproduces the active first 29 amino acids of growth-hormone-releasing hormone. It signals a functioning pituitary to release GH rather than supplying GH directly. This mechanism explains its historical diagnostic and pediatric uses and its later wellness positioning. In adults, the intended goals are often improved recovery, sleep and body composition, but pituitary responsiveness and the underlying reason for symptoms affect what a GH signal can accomplish.
Gym & peptide talk / claims Wellness and gym conversations call it a natural-GH support option, especially for feeling recovered and less run-down with age. Fans discuss deeper sleep, a leaner waist and gradual changes rather than dramatic size gains. It is not equivalent to taking prescribed growth hormone.
Compound profileTSM
Tesamorelin
What it is A GHRH analogue that raises GH and IGF-1.
Purpose & how it works Tesamorelin stimulates the GH/IGF-1 axis through a GHRH-like signal. Its approved medical purpose is reducing excess abdominal fat in adults with HIV-associated lipodystrophy. This primarily concerns visceral fat, the fat surrounding internal organs, rather than simply the pinchable fat under the skin. That distinction explains the emphasis on waist size. It is not a general weight-loss medicine, and reducing visceral fat need not produce a large drop on the scale.
Gym & peptide talk / claims The gym pitch is a smaller waist, less deep belly fat and improved body composition, often described as recomp. Some expect sharper abs or better recovery. A flatter-looking stomach does not establish selective removal of every type of belly fat or added muscle.
Compound profileIG01 / IG1
IGF-1 LR3
What it is A modified insulin-like growth factor analogue with altered binding to IGF-binding proteins.
Purpose & how it works IGF-1 is a growth signal involved in tissue growth and nutrient use. LR3 is a modified analogue designed to behave differently with IGF-binding proteins, altering how much activity is available to cells. The intended bodybuilding purpose is stronger growth-related signaling and nutrient uptake. It is not the same molecule as normal IGF-1 or the prescription medicine mecasermin, and it does not act only on skeletal muscle.
Gym & peptide talk / claims Fans talk about fuller muscles, better pumps, nutrient partitioning and bringing up lagging body parts. Some claim hyperplasia, meaning creation of more muscle fibers rather than enlargement of existing ones. Human bodybuilding claims of targeted growth or new fibers are not established; low blood sugar is a serious concern.
Compound profileFM2
MGF
What it is Mechano growth factor refers to an IGF-1 splice-variant concept and, commercially, an associated E-peptide.
Purpose & how it works MGF is linked to the IGF-1 gene's response to mechanical stress. The commercially discussed fragment is intended to influence muscle progenitor or satellite cells, which help repair and support muscle tissue. The proposed purpose is to improve repair after hard training and support muscle adaptation. The natural precursor, its gene expression and a synthetic E-peptide are different things; describing one does not prove the others work as products.
Gym & peptide talk / claims The bodybuilding story centers on activating satellite cells, repairing damaged muscle and helping a lagging muscle grow. Satellite cells are support cells involved in repair, not an automatic switch for new muscle. Claims of site-specific growth and dramatic hypertrophy go beyond established human outcomes.
Compound profileFMP2
PEG-MGF
What it is A pegylated MGF-related peptide; polyethylene glycol is attached to alter its behavior in the body.
Purpose & how it works PEG-MGF attaches polyethylene glycol to an MGF-related construct to change its persistence and handling in the body. The intent is a longer-lasting version of the muscle-repair signal proposed for MGF. That makes duration the main design claim. It does not establish that longer exposure produces better repair, and chemically modifying a peptide can also change distribution, interactions and immune recognition.
Gym & peptide talk / claims Gym discussions describe it as extended recovery support, sometimes contrasted with the growth-focused reputation of IGF-1 LR3. Fans talk about muscle repair, satellite cells and bringing up weak body parts. The marketed sequence and pegylation details matter, and those physique outcomes are unproven.
