# When to DIY vs Outsource: A Decision Framework

**Phase:** 10 — Cost-benefit synthesis
**Last updated:** 2026-04-22
**Answers user anchor question 3 and 5 (equipment cost + what real labs use) in a practical decision tool.**

---

## Key takeaways — the bottom line

- **< 5 vials/year:** outsource. Ship to testing.trans.diy (donation), Finnrick (free, peptides only), Janoshik ($120-$300), or Trans Harm Reduction (donation).
- **5-30 vials/year:** outsource + maintain basic UV-Vis + LAL gel-clot at home for fast screening. Bronze tier (<$2k).
- **30-100 vials/year:** the crossover zone. Silver tier HPLC (~$10k) starts to pay back over 3-5 years if you also value turnaround speed.
- **100+ vials/year:** in-house HPLC wins on both marginal cost and turnaround. Outsource only the tests you can't do well in-house (LC-MS confirmation, sterility USP <71>, rFC endotoxin with higher precision).
- **Endotoxin is always worth screening**: the incremental cost of in-house LAL gel-clot is low (~$10-30/test materials) and community labs rarely offer it. Hybrid (HPLC in-house, endotoxin in-house, sterility outsourced) is the sweet spot for a homebrewer or a large DIY HRT group.

## The decision tree

```
How many vials/year do you need to test?
│
├── < 5/year ──────────── Outsource everything.
│                         HRT → testing.trans.diy or THR ($30-300).
│                         Peptides → Finnrick (free) or Janoshik ($300).
│                         Anabolics → Janoshik ($120).
│
├── 5-30/year ─────────── Outsource HPLC. Bronze in-house:
│                         UV-Vis for crude potency spot-check ($3k).
│                         LAL gel-clot kit for endotoxin ($500-1000/yr).
│                         Send "keep" vials out for full HPLC.
│
├── 30-100/year ───────── Silver in-house ($8-15k): Agilent 1100 + VWD/DAD.
│                         In-house LAL gel-clot + LRW + CSE.
│                         Outsource LC-MS confirmation quarterly.
│                         Outsource sterility (14-day turnaround kills in-house).
│
└── > 100/year ────────── Gold in-house ($25-50k): Agilent 1260 or 1200 + DAD.
                          In-house LAL (maybe rFC for precision).
                          Consider used single-quad LC-MS ($35-60k) for ID confirmation.
                          Still outsource sterility and heavy metals.
```

## Why the thresholds land where they do

### Below 5 vials/year

You can't justify equipment. Even a Bronze-tier Agilent Cary 60 UV-Vis at $3,000 used (see `research/_sources/listings-snapshot-2026-04-22.md`) plus consumables pays back at 5+ tests if savings per test are $500. At 5 tests/year you'd need to save $600/test to break even in one year — impossible when outsourced HRT testing ranges from free (testing.trans.diy, donation) to $120 (Janoshik).

**Recommendation:** testing.trans.diy if your vendor is listed; Trans Harm Reduction if you're in the EU; Janoshik if you need a fast, detailed COA with raw chromatogram.

### 5-30 vials/year

You could benefit from fast in-house screening — turnaround matters when you have injections queued — but you can't amortize an HPLC over this volume.

**Bronze-tier rationale:**
- Used UV-Vis spectrophotometer (Cary 60 at ~$3,000 per 2026-04 listings) — sufficient for crude potency estimate (±15-20%) with methanol extraction. Catches gross under-dosing.
- LAL gel-clot kit (Pyrotell 0.25 EU/mL 5×5 mL at ~$595 = 250 tests → $2.38/test reagent; per `research/_sources/lal-kit-pricing-2026-04-22.md`) + Control Standard Endotoxin ($251/6 vials) + LAL Reagent Water ($130-380/case depending on size).
- Depyrogenation oven (dry heat 250 °C ≥ 30 min) — used $500-2000 or a modified glassware-sterilization oven.
- Laminar flow hood (used Baker SG400 at ~$3,475 per 2026-04 listings) for sterile sample handling.

**Cost envelope:** $4,000-8,000 total. Covers rough-potency screening + endotoxin in-house. HPLC work still ships out.

### 30-100 vials/year

Silver tier HPLC becomes viable. A used Agilent 1100 with VWD (variable-wavelength detector) from Marshall Scientific was listed at **$12,390** on sale (regular $14,390) with 180-day parts & labor warranty as of April 2026 (per `research/_sources/listings-snapshot-2026-04-22.md`), including pump, autosampler, column heater, degasser, and a PC with ChemStation 4.3. LabX 1100 listings have been as low as **$10,500** (2025-05-09 snapshot).

**Important 2026 inflection:** Agilent 1100 series reaches end-of-life support on January 31, 2026. This means:
- Aftermarket parts are still widely available but manufacturer support ends.
- Used-market prices are beginning to drop (supply increase as labs upgrade).
- The Agilent 1200 / 1260 refurbs are the smarter 5-year buy (same architecture, still supported).

**Break-even math at 50 tests/year**, outsourced vs in-house:
- Outsourced Janoshik steroid test: $120/test × 50 = $6,000/yr.
- In-house Silver tier: $10,000 capex + $5/test marginal × 50 = $10,250 year-1, then $250/yr thereafter.
- Year 1 deficit: $4,250. Break-even month in year 2.
- After 3 years: outsourced = $18,000; in-house = $10,750 → saves $7,250.
- After 5 years: outsourced = $30,000; in-house = $11,250 → saves $18,750.

In-house wins on total cost if your horizon is > 2 years. At 100 tests/year it wins in year 1.

**You still can't do at Silver tier:**
- LC-MS confirmation (no MS instrument)
- ISO-accredited sterility (no incubator with documented BI pyrogen-free protocol)
- Heavy metals (no ICP-MS — those are $50-100k used)
- Precise rFC endotoxin (gel-clot is OK; if you need 0.005 EU/mL LoQ, you need a fluorescence reader)

Route these to Janoshik or similar.

### Over 100 vials/year

Gold tier becomes the right answer. An Agilent 1260 Infinity I with quat pump, DAD, and FLD was listed at **$47,995 refurb** (Marshall via LabX, 2026-04). Agilent 1260 Infinity II 7-unit system was at **$29,997 refurb**.

With DAD, you can confirm identity by UV spectral match (see `research/08-interpretation-qc/identity-confirmation.md`) — cutting your need for outsourced MS confirmation by ~80%.

At 200 tests/year:
- Outsourced: $120 × 200 = $24,000/yr
- In-house Gold: $30k capex + $6/test marginal × 200 = $31,200 year-1, then $1,200/yr
- Year 2 savings: $22,800

Break-even in year 2 even for Gold tier. This is where a large DIY HRT homebrewing operation or a community co-op testing service should land.

## International note — state-funded AAS testing in CH and NL

Two state or state-adjacent harm-reduction services worldwide accept anabolic-androgenic steroids as a formal intake class, and **they are free or insurance-covered**. Neither accepts HRT for gender-affirming care today, but both are technically capable of running oil-based hormone analyses on the same instruments (GC-MS in Zürich; UPLC-QTOF-MS/MS in Haarlem). **If you are in Switzerland or the Netherlands and you are testing testosterone esters specifically, the in-house-vs-outsource math changes** — the outsource cost is zero or insurance-covered rather than $120 Janoshik. Detail in [`research/01-existing-services/international-state-funded.md`](../01-existing-services/international-state-funded.md).

For estradiol esters and other HRT-for-gender-affirming-care substances, neither service currently extends scope; advocacy could plausibly move them to do so since the technical capability is already deployed. This is the most plausible non-Anglo extension vector for community HRT testing.

## Endotoxin — the special case

Endotoxin testing is the most glaringly under-provisioned test in the community HRT/peptide space:

- testing.trans.diy: does not test for endotoxin.
- Trans Harm Reduction: does not offer endotoxin.
- Artemis Analytical: not publicly disclosed.
- Finnrick: paid add-on at $110/test (secondary source; see `research/_sources/janoshik-pricing-2026-04-22.md`).
- Janoshik: $180/test standalone; included in Package A+ ($828+).

**In-house gel-clot LAL is achievable at Bronze tier with ~$1,000 in first-year kit** (LAL reagent + CSE + LRW + water bath/incubator + depyrogenation oven + pipetting hardware). Per-test reagent cost drops to ~$5-15 at scale (see `research/03-microbial-pyrogen/home-lab-endotoxin-feasibility.md`).

At 20+ endotoxin tests/year the in-house math beats outsourcing Janoshik:
- Outsourced: $180 × 20 = $3,600/yr
- In-house: $1,000 capex + $10/test × 20 = $1,200 year-1, then $200/yr
- Break-even at ~15 tests year-1; any higher volume is dominant savings.

Even if your HPLC work stays outsourced, **in-house endotoxin testing is almost always worth it** for anyone injecting self-sourced HRT or peptides weekly.

## Behaviour-change evidence supporting the in-house case

The harm-reduction case for in-house testing isn't only economic. Two peer-reviewed studies (full citations in [`research/literature.md`](../literature.md)) directly measure user behaviour after community testing results are returned:

- **Measham & Turnbull 2021** (*Int J Drug Policy*; doi:10.1016/j.drugpo.2021.103270) — UK festival drug-checking, 1,482 baseline consultations, 130 follow-ups three months later. **>50% disposed of samples that came back as other-than-expected; ~40% reduced dose for samples-as-expected; ~20% alerted friends.** Stated intentions correlated strongly with reported actions.
- **Piatkowski et al. 2025b** (*Harm Reduction Journal*; doi:10.1186/s12954-025-01270-4) — community AAS testing pilot, 58 samples + 25 qualitative interviews. After dissemination, users reported modifying usage practices and reduced trust in specific suppliers.

For HRT, "dispose and re-buy" is harder than for recreational drugs (the supply chain is slower and more expensive), so behaviour change leans toward dose adjustment, vendor-switching, and warning peers — but the underlying mechanism transfers. **Testing changes user decisions; faster turnaround amplifies that effect.** In-house cuts turnaround from 2–4 weeks to 2–4 days, which is operationally significant if you're a homebrewer holding a batch back from your community pending results.

## Why the hybrid model wins

The smartest community setup in 2026 looks like this:

- **In-house:** HPLC with VWD or DAD (Silver/Gold tier); LAL gel-clot endotoxin; laminar flow hood + depyrogenation oven for sample prep.
- **Outsourced:** LC-MS confirmation for novel or ambiguous results; USP <71> sterility (takes 14 days — you'd rather not wait); ICP-MS heavy metals; rFC when higher precision than gel-clot is warranted.

This mirrors what the partner labs behind Finnrick (MZ Biolabs, Krause, Chromate) actually do: UV-HPLC as workhorse, MS as confirmation for a minority of samples. It also matches what testing.trans.diy appears to do (HPLC primary, no contamination panel).

See `research/10-cost-benefit/hybrid-model.md` for implementation detail.

## Checklist: do you need to DIY at all?

Before spending $10k+, ask yourself:

1. **Is there a good outsource option for your compound class?**
   - Peptides + you're US-based → Finnrick free.
   - HRT + you're OK with slow turnaround → testing.trans.diy / Trans Harm Reduction.
   - Anabolics → Janoshik.
   - All of the above + you want fast + detailed → Janoshik paid.

2. **Is turnaround the bottleneck?** If you're a homebrewer who can't ship to market until you have test results, in-house cuts turnaround from 2-4 weeks to 2-4 days.

3. **Do you have the skill budget?** Method validation, mobile-phase prep, column care, troubleshooting — realistically 50-200 hours to get competent (see `research/05-home-lab-setup/qualifications.md` when that phase publishes).

4. **Do you have the space?** HPLC needs a dedicated 20A circuit, ~4 ft of bench, ventilation for solvents, and secure solvent storage.

5. **Do you have a disposal plan?** HPLC-grade solvents are regulated hazardous waste. Figure this out before buying the instrument.

If the answer to any of (3), (4), (5) is "not yet," outsource for now and defer the capex decision.
