Gedocumenteerde cofactoren
Wat goedgekeurde productinformatie en de wetenschappelijke literatuur documenteren over nutriënt- en cofactoraspecten van bepaalde peptideklassen — neutraal, met bron.
Deze pagina geeft uitsluitend weer wat productinformatie en studies documenteren. Het is GEEN supplementaanbeveling, geen stack en geen gebruiksaanwijzing. Geen doseringen, geen aankoopbronnen. Beslissingen over suppletie neem je samen met je arts.
Bone-building peptides (teriparatide, abaloparatide)
For the approved osteoporosis anabolics, the prescribing information explicitly notes adequate intake of two bone co-factors — not as an extra recommendation from this site, but as part of the approved use.
The label notes adequate calcium intake if the diet is insufficient — calcium is the raw material the bone-building effect relies on.
The label notes adequate vitamin D intake; vitamin D is required for intestinal calcium absorption.
GLP-1 & incretin agents (semaglutide, tirzepatide, etc.)
With rapid weight loss on incretin agents, the scientific literature discusses accompanying measures to preserve the quality of weight loss. These are not directives from this site but considerations documented in reviews.
In studies a portion of weight loss comes from lean mass; reviews discuss adequate protein intake to help preserve muscle mass.
The literature discusses resistance training alongside protein intake to limit the share of lean mass lost. (Not a supplement, but a documented accompanying factor.)
Somatostatin analogues (octreotide, lanreotide, pasireotide)
Somatostatin analogues can inhibit digestive enzyme and bile secretion, which may cause fat malabsorption. The prescribing information documents the resulting nutrient considerations and recommended monitoring.
The label reports depressed vitamin B12 levels in some patients and notes monitoring of B12 levels during therapy.
With the documented fat malabsorption (steatorrhea), fat-soluble vitamins may theoretically be affected; the label advises evaluation if symptoms newly appear or worsen.
Special case: copper peptide (GHK-Cu)
A common misconception: GHK-Cu is itself a copper complex — the co-factor (copper) is part of the molecule. The chemistry does not imply taking an additional copper supplement.
GHK-Cu carries the copper ion as an integral part — this is a chemical property, not an add-on intake.

Healing / tissue peptides (BPC-157, TB-500, GHK-Cu, KPV …)
Anecdotal — mentioned in rehab/healing communities, no studies on this, not a recommendation.
Mentioned around tissue-repair peptides as building blocks of collagen synthesis. Anecdotal, not study-backed.
Mentioned in wound-healing discussions; general nutritional building blocks, no peptide-specific evidence.
GH secretagogues (ipamorelin, CJC-1295, GHRP, sermorelin …)
Anecdotal — discussed in fitness communities, no robust studies on the combination.
Discussed around GH secretagogues. Anecdotal, without robust human data on the combination.
As GH release occurs during sleep, good sleep / melatonin are raised in communities. Anecdotal.
GLP-1 & incretin agents (semaglutide, tirzepatide …)
Anecdotal — discussed in weight-loss communities; the DOCUMENTED aspects (protein, resistance training) are in the incretin section above.
Mentioned in communities for digestive issues and fluid loss. Anecdotal.
Raised in communities with strongly reduced food intake. Anecdotal; monitoring belongs under medical supervision.
Cosmetic peptides topical (GHK-Cu, argireline, matrixyl …)
Anecdotal — discussed in skincare communities, little robust data on applying actives together.
Often discussed topically alongside cosmetic peptides. Anecdotal; some combinations (e.g. vitamin C) may affect tolerability.
Nootropic peptides (selank, semax, cerebrolysin, DSIP)
Anecdotal — discussed in nootropic communities, no studies on these combinations.
General 'brain' basics, mentioned in communities around nootropic peptides. Anecdotal and non-specific.
Raised around selank/stress in communities. Anecdotal, without studies on the combination.
Longevity peptides (epitalon, MOTS-c, humanin)
Anecdotal — discussed in longevity communities, very limited human data.
Mentioned in anti-aging communities around longevity peptides. Anecdotal, no peptide-specific evidence.
Raised due to the discussed pineal/sleep links of epitalon. Anecdotal.
Growth/muscle peptides (IGF-1 LR3, MGF, follistatin)
Anecdotal — discussed in bodybuilding communities, without studies on the combination.
General training basics, mentioned in communities around growth peptides. Anecdotal, no peptide-specific evidence.
Melanocortin peptides (melanotan II, PT-141)
Anecdotal — discussed in communities. Note: melanotan II is unapproved and carries safety risks (see its page).
Skin-protection topics are discussed around melanotan II. Anecdotal — no substitute for dermatological monitoring; the substance itself is unapproved.
