Reference

Dosing information, separated by source kind

A dose is not an abstract fact with a single owner. Regulators approve one schedule, clinical trials study another, clinics observe a third, and online forums discuss a fourth. Therapept separates these tiers completely instead of averaging them.

The 5 Source Tiers Explained

Open Full Comparison Table →

Every numerical record on Therapept belongs strictly to one of five source categories. They are never averaged together, and community discussions are never used to validate an unapproved dose.

Official

Official product dosing

Approved indication, route, dose, frequency and titration, sourced only from the FDA label, DailyMed or the manufacturer's prescribing information.

Human study

Published human study doses

Intervention parameters reported in individual published human studies. Each study stays separate; parameters are never aggregated across studies.

Animal

Published animal studies

Clearly labelled animal research. Animal dosing is never visually mixed with human study data and is not evidence of human response.

Clinical ref.

Clinical / professional references

Protocols published by identifiable professional, clinic or pharmacy sources, recorded with author/clinic, date accessed and context.

Community

Community-reported ranges

What people report discussing or doing in forums, on Reddit and in videos. Included only to show demand and reported practice — never as clinical evidence.

Important Boundary: Therapept does not provide personal prescribing advice or endorse unapproved usage. Where no official FDA-approved label exists, that absence is stated plainly.

OfficialApproved Product Label

Liraglutide

GLP-1 receptor agonist (acylated GLP-1 analogue)

An approved drug with a labelled dose schedule. The label is the authoritative source; research-chemical copies of liraglutide are not the labelled product.

Available Tiers:Official
Human studyNo Approved Dose

Ipamorelin

Growth hormone secretagogue; ghrelin receptor (GHS-R1a) agonist. Synthetic pentapeptide containing unnatural amino acids

No approved product exists. Human data are limited to pharmacology studies of the compound itself; everything beyond those studies comes from lower source tiers.

Available Tiers:Human studyAnimalCommunity
Human studyNo Approved Dose

CJC-1295

Growth hormone-releasing hormone (GHRH) analogue. Supplied in two chemically distinct forms

Two distinct molecules share this name. The published human trials used the DAC (albumin-binding) form; the non-DAC fragment sold as “Mod GRF 1-29” has no comparable published human dose data in this file.

Available Tiers:Human studyClinical ref.Community
Human studyNo Approved Dose

BPC-157

Synthetic 15-residue peptide corresponding to a partial sequence of human gastric juice protein BPC

No approved product and no registered human trials in this file. The only human data indexed are a small retrospective case series; animal literature is extensive but comes from largely one research network.

Available Tiers:Human studyCommunity
CommunityNo Approved Dose

TB-500

Synthetic acetylated heptapeptide corresponding to the actin-binding region of thymosin beta-4 (residues 17–23)

The published human dose picture for the TB-500 fragment specifically is effectively empty: the wound-healing literature concerns full-length thymosin β4, a different molecule. Compound-specific confusion is the story here.

Available Tiers:Community
Human studyNo Approved Dose

Melanotan II

Cyclic heptapeptide; non-selective melanocortin receptor agonist (alpha-MSH analogue)

A pilot Phase I study exists; no approved product. The study's own conclusion was about dose selection for future Phase I work, not therapy.

Available Tiers:Human studyCommunity
OfficialApproved Product Label

Semaglutide

GLP-1 receptor agonist (acylated GLP-1 analogue)

An approved drug with labelled schedules. Unapproved GLP-1 products are a separate regulatory matter and their contents are not the labelled drug.

Available Tiers:OfficialHuman study
Human studyNo Approved Dose

Retatrutide

Investigational triple agonist of GIP, GLP-1 and glucagon receptors

An investigational triple agonist (GIP, GLP-1, and glucagon receptors) in Phase 3 clinical development. There is no FDA-approved formulation, no approved prescribing label exists, and research chemicals sold online are unverified for purity or sterility.

Available Tiers:Human studyClinical ref.Community
OfficialApproved Product Label

Tirzepatide

Dual GIP and GLP-1 receptor agonist

An approved dual GIP/GLP-1 receptor agonist with authoritative prescribing labels. Compounded or research-grade copies are chemically distinct and lack FDA safety verification.

Available Tiers:OfficialHuman study
OfficialApproved Product Label

Tesamorelin

Stabilised GHRH analogue — human GHRH(1-44) amide, N-terminally acylated

An FDA-approved growth hormone-releasing factor analogue specifically indicated for HIV-associated lipodystrophy. Other cosmetic, bodybuilding, or anti-aging uses discussed online are unapproved.

Available Tiers:OfficialHuman studyCommunity
Human studyNo Approved Dose

Sermorelin

GHRH analogue — human GHRH (1-29) amide

A 29-amino acid GHRH fragment (GHRH 1-29 amide). Formerly FDA-approved as Geref for diagnostic pituitary evaluation and idiopathic growth hormone deficiency.

Available Tiers:Human studyCommunity
Human studyNo Approved Dose

GHK-Cu

Copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. Cosmetic ingredient under the INCI name Copper Tripeptide-1

A naturally occurring copper tripeptide (glycyl-L-histidyl-L-lysine:copper). Primarily studied in topical dermatological formulations and animal tissue regeneration models.

Coverage Note:

Looking for a compound not listed here? If a substance is absent from this hub, it means Therapept has not yet indexed verified clinical trial or official label records for it — not that no discussion exists. Consult the Peptide Library (42 compounds) for chemical identities and regulatory classifications.
